RTL

RTL, formerly Radio Luxembourg, is a French commercial radio network owned by the RTL Group. Founded in 1933 as Radio Luxembourg, the station's name was changed to RTL in 1966. It broadcast from outside France until 1981, because only public stations had been allowed until then.

It is a general-interest, news, talk and music station, broadcasting nationally ("category E" as classified by the CSA'
On 19 December 1929 the Grand Duchy of Luxembourg established a state monopoly on broadcasting, but the law provided for possible concessions to private companies who wanted to use radio bandwidth, with the state charging a fixed amount for private use of radio.

The Société Luxembourgeoise d'Études Radiophoniques (SLER) was founded on 11 May 1929 with the aim of obtaining an eventual broadcasting contract from the Luxembourg government. This company was run by Luxembourger François Anen, French publisher Henry Etienne, and French engineer Jean le Duc representing the Compagnie des Compteurs de Montrouge, which possessed 84% of the project's capital and which had signed a secret agreement to work with the group CSF, the main stockholder in Radio Paris. Radio Paris wanted to set up a powerful peripheral radio station in Luxembourg, outside of the strict French regulations, which only allowed public stations.[1] An agreement between the SLER and the Luxembourg government signed on 29 September 1930 with a duration of 25 years ensured the Luxembourg government a fee of 30% on future profits of the station. The agreement also set up a committee for programming and a technical committee which allowed the government to regulate the private station.

The Compagnie Luxembourgeoise de Radiodiffusion (CLR) was founded on 30 May 1931, officially replacing the SLER.

On 14 January 1933 experimental broadcasts by Radio Luxembourg began, at 1191 mètres (200 kW), an unauthorized wavelength, from the longwave transmitter at Junglinster. The official opening of broadcast was on 15 March 1933 at 19:00 with a pre-recorded concert of light music. Radio Luxembourg broadcast each evening from 19:00 to 23:00, in German, French and Dutch and was therefore the only French-language private broadcaster available in France and Belgium. Programmes in English débuted on 3 December 1933 under the editorial guidance of Stephen Williams.

The station closed down at the outbreak of World War II in 1939, but it resumed service after the War.

Beginning in 1946, it could be heard easily in France. Until the 1980s, only the French public radio networks could transmit from France itself. Radio Luxembourg was one of private "peripheral" networks transmitting from abroad.

Quickly, Radio Luxembourg gained a large audience in France. In the 1960s, it was faced with the success of another peripheral network from Germany, Europe 1, which adopted a modern tone and gained a young audience.

RTL
Radio Luxembourg's changing environment led to the station being renamed "RTL" on 11 October 1966, less obviously mentioning its connection with Luxembourg (the acronym being short for Radio Télévision Luxembourg).

During the May 1968 crisis, the French public radio networks were on strike and TV was not independent from the government. RTL and Europe 1 were the main ways of obtaining independent information for the French people. They were nicknamed "barricades radio".

Unlike the British government's treatment of the Luxembourg English service, which was never allowed to have a landline from London, the French service has long had its main studios in Paris, with a landline from there to the transmitter. Consequently, it appears to the listener to be simply a big French national radio station, and the Luxembourg connection is played down.

In 1981, under president François Mitterrand, privately run radio stations were allowed to broadcast in France. RTL, now broadcasting in France mostly at 104.3 MHz, was the radio network with the most listeners from 1981 to 2002.

Whereas Luxembourg's English service was always centred on light entertainment and popular music, RTL in French is a mixed station: about 50% of its output is speech-based, with a strong focus on news and current affairs and a large team of respected journalists.

Radio Luxembourg's two main national competitors are Europe 1 (another out-of-country commercial station, broadcasting from Saarland, again with Paris studios) and the state-owned France Inter. All three stations have very high-powered transmitters occupying long-wave frequencies that date back many decades.

The French service has called itself RTL for many years. It still broadcasts on 234 kHz long wave using the Beidweiler Longwave Transmitter, but nowadays also on a network of FM transmitters throughout France, as well as on the internet, cable and satellite.

In 1991 a separate RTL Belgian service in French, called Bel-RTL, was established. Intended for the French-speaking part of Belgium and with studios in Brussels, this station is licensed (along with many competing commercial stations) by the Belgian Government, with a network of FM transmitters covering Brussels and Wallonia, and no particular connection with the Grand Duchy of Luxembourg other than its ownership by the RTL parent company.

Since 2000, it has gone through a crisis. Indeed, in order to stop the aging of RTL's audience, station managers imposed changes which have annoyed many listeners. From 2000 to 2002, RTL lost a third of its listeners, falling to second in the ratings behind NRJ. In November 2006, it re-took the lead in the French radio ratings only to succumb again in July 2012 to NRJ.

Serge Gnabry

Serge David Gnabry (born 14 July 1995) is a German professional footballer who plays as a winger for Bayern Munich and the Germany national team.

Gnabry started his career in England with Arsenal in the Premier League, making his professional debut in September 2012. He also had a brief spell on loan with West Bromwich Albion before moving back to Germany to join Werder Bremen for a reported fee of £5 million in August 2016.

After appearing for Germany at various youth levels, Gnabry made his senior international debut in November 2016 in a 2018 FIFA World Cup qualification match against San Marino. He scored a hat-trick in the 8–0 win
Early life
Gnabry was born in Stuttgart, Baden-Württemberg, to an Ivorian father and a German mother.[4][5] In his youth, Gnabry was a talented sprinter but ultimately chose football over track and field.[6]

Club career
Arsenal
Gnabry's former club VfB Stuttgart agreed to a £100,000 deal with Premier League side Arsenal in 2010, but he had to wait until 2011, when he was 16, to join the English side.[7][8] Gnabry officially joined Arsenal for the 2011–12 season. He played for the under-18s for the majority of the season but was then promoted to the reserves after impressive displays.[9] By the end of the season, Gnabry had played six games, scoring two goals.[9]

2012–13 season
The 2012–13 season started off well for Gnabry after he was called up to the Arsenal first team for a pre-season friendly against FC Köln. He played 24 minutes after coming on at half-time and was replaced by Marouane Chamakh in the 69th minute.[10] He then made his professional first-team debut for Arsenal on 26 September 2012 against Coventry City in the League Cup as a 72nd-minute substitute for Alex Oxlade-Chamberlain as Arsenal routed Coventry 6–1.[11] On 20 October 2012, he made his Premier League debut in the 1–0 defeat against Norwich City at Carrow Road. At 17 years and 98 days, he became Arsenal's second-youngest player in the league's history after Jack Wilshere.[12] Four days later, he made his Champions League debut, coming on as a substitute in Arsenal's 2–0 home loss to FC Schalke 04.[13]

On 25 March 2013, Gnabry scored the only goal in a 1–0 win over CSKA Moscow U19s in the quarter-finals of the NextGen Series.[14] He scored a late equaliser against Chelsea U19s to make it 3–3 in the semi-finals of the same competition, before Arsenal lost 4–3 in extra time.[15] In the following game on 8 April, Gnabry scored a goal against Liverpool U21s in an eventual 3–2 away defeat.[16]

2013–14 season
In the first game of the 2013–14 season, Gnabry was included in Arsenal's first-team squad against Aston Villa and started the game on the bench.[17] He then made his first start for the club on 22 September 2013 in the Premier League against Stoke City after Theo Walcott was ruled out just before kick-off. He played 73 minutes before being subbed out for Ryo Miyaichi as Arsenal won the match 3–1.[18] He scored his first professional goal in the next league match against Swansea City to lead Arsenal to a 2–1 victory and leave them top of the Premier League table.[19] On 26 October, he won a penalty away at Crystal Palace in an eventual 2–0 victory for Arsenal.[20] Gnabry's impressive start to the season resulted in a nomination for the 2013 Golden Boy Award,[21] and a new five-year contract with Arsenal.[22]

2014–15 seas
Gnabry missed most of the 2014–15 season due to a serious knee injury which kept him away from the first team for over a year.[23] However, he captained and played 65 minutes for the Arsenal U21s as they beat Newcastle United U21s 2–1 in February 2015.[24]

Loan to West Bromwich Albion
On 7 August 2015, Gnabry joined West Bromwich Albion on a season-long loan to gain first-team experience.[25] He made his debut as a substitute in a 3–2 defeat to Chelsea on 23 August 2015.[26] In January, he was recalled from his loan after lacking first-team action at West Brom.[27] He finished the 2015–16 season with a Premier League appearance and two League Cup appearances.[28][29]

Werder Bremen
On 31 August 2016, Gnabry signed for Bundesliga side Werder Bremen for a reported transfer fee of £5 million.[30][31] Arsenal manager Arsène Wenger had wanted to extend Gnabry's contract at Arsenal before his move, but a lack of first-team opportunities meant that the midfielder sought a move elsewhere.[32][33]

He scored his first goal for Werder Bremen on 17 September 2016 in a 4–1 away loss to Borussia Mönchengladbach.[34]

In his single season at the club, he made 27 league appearances scoring 11 goals[35] while Werder Bremen finished 8th in the Bundesliga.[36]

Bayern Munich
Loan to 1899 Hoffenheim
On 11 June 2017, Bayern Munich announced the signing of Gnabry on a three-year deal for €8 million after activating a clause in his contract with Werder Bremen.[37]

On 14 June 2017, Bayern Munich announced that Serge Gnabry was moving to 1899 Hoffenheim on a season-long loan. Gnabry had wished for the move to gain more experience.[38] He scored his first and second league goal in the 4–0 victory over RB Leipzig.[39] He scored 10 goals in his 22 appearances in the season helping Hoffenheim to finish third in the league table and secured a Champions League spot for the next season.[40][41] He finished the 2017–18 season with 10 goals in 26 appearances.[42] He also made an appearance in the Regionalliga Südwest for the reserve team.[42]

2018–19 season
On 2 July 2018, Gnabry was presented as a Bayern Munich player. Gnabry was assigned the jersey number 22.[43] On 1 September, Gnabry made his Bundesliga debut for Bayern Munich in a 3–0 win at Stuttgart when he came on as a substitute in the 77th minute.[44] On 3 November 2018, Gnabry scored his first Bundesliga goal for Bayern Munich in a 1–1 draw against Freiburg.[45] On 1 December 2018, Gnabry scored two goals in a 2–1 win against his former club Werder Bremen.[46] On 2 March 2019, Gnabry scored Bayern Munich's 4000th Bundesliga goal during a 5–1 win over Gladbach, helping the club become the first team to achieve the milestone.[47]

Gnabry finished the Bundesliga season as Bayern's second top scorer with 10 goals in 30 matches. Gnabry won his first Bundesliga title as Bayern finished two points above Dortmund with 78 points.

International career
Youth teams
Gnabry represented Germany at various youth levels, including under-16, under-17 and under-18 levels.[6] In 2017 he was part of the U21 team which won the European Under-21 Championship.[48]

2016 Summer Olympics
On 15 July 2016, Germany selected Gnabry to participate in the 2016 Olympic Games.[49] On 4 August, he started for Germany against Mexico and scored Germany's first goal after 58 minutes in a 2–2 draw with Mexico.[50] Three days later, he tripled his tally by putting two past South Korea, the second being a stoppage time free kick that helped Germany salvage a point in a 3–3 draw.[51] On 10 August, Gnabry contributed two more goals in a 10–0 defeat of Fiji.[52] In Germany's quarter-final match against Portugal, he scored his sixth goal of the tournament just before half-time as Germany prevailed with a 4–0 win.[53] He ended the tournament as the joint top scorer along with his teammate Nils Petersen,[54] helping Germany to win the silver medal.[55]

Senior team
On 4 November 2016, Gnabry received his first call-up to the German senior team.[56] Seven days later, he scored three goals on his debut in a 2018 World Cup qualifier against San Marino in an 8–0 away win

زحل

زُحَل (رمزه: Saturn symbol.svg)، واسمه مشتق من الجذر "زَحَل" بمعنى تنحّى وتباعد. ويُقال إنه سمي زُحَل لبعده في السماء، أما الاسم اللاتيني فهو "ساتورن" وهو إله الزراعة والحصاد عند الرومان، ويُمثل رمزه منجل الإله الروماني سالف الذكر.

زحل هو الكوكب السادس من حيث البُعد عن الشمس وهو ثاني أكبر كوكب في النظام الشمسي بعد المشتري، ويُصنف زحل ضمن الكواكب الغازية مثل المشتري وأورانوس ونبتون. وهذه الكواكب الأربعة معاً تُدعى "الكواكب الجوفيانية" بمعنى "أشباه المشتري". يعدّ نصف قطر هذا الكوكب أضخم بتسع مرّات من نصف قطر الأرض، إلا أن كثافته تصل إلى ثمن كثافة الأرض، أما كتلته فتفوق كتلة الأرض بخمسة وتسعين مرة.

تعدّ الظروف البيئية على سطح زحل ظروفاً متطرفة بسبب كتلته الكبيرة وقوة جاذبيته، ويقول الخبراء إن درجات الحرارة والضغط الفائق فيه يفوق قدرة العلماء والتقنيات الموجودة على إعداد شيء مشابه لها وإجراء التجارب عليه في المختبرات. يتكون زحل بنسبة عالية من غاز الهيدروجين وجزء قليل من الهيليوم، أما الجزء الداخلي منه فيتكون من صخور وجليد محاطٍ بطبقة عريضة من الهيدروجين المعدني وطبقة خارجية غازية.

يُعتقد أن التيار الكهربائي الموجود بطبقة الهيدروجين المعدنية يساهم في زيادة قوة وجاذبية الحقل المغناطيسي الخاص بهذا الكوكب، والذي يقل حدة بشكل بسيط عن ذاك الخاص بالأرض وتصل قوته إلى واحد على عشرين من قوة الحقل المغناطيسي الخاص بالمشتري. سرعة الرياح على سطحه تقارب 1800 كم/س، وهي سرعة كبيرة جداً مقارنة مع سرعة الرياح على سطح المشتري.

يتميز زحل بتسع حلقات من الجليد والغبار تدور حوله في مستوى واحد مما يعطيه شكلاً مميزاً. يوجد واحد وستون قمراً معروفاً يدور حول زحل باستثناء القميرات الصغيرة، وقد تمّ تسمية 53 قمراً منها بشكل رسمي. من بين هذه الأقمار، يُعدّ "تيتان" القمر الأكبر، وهو كذلك ثاني أكبر قمر في المجموعة الشمسية، بعد "غانيميد" التابع للمشتري، وهو أكبر حجماً من كوكب عطارد، ويُعتبر القمر الوحيد في المجموعة الشمسية ذا الغلاف الجوي المعتبر.

كان جاليليو أوّل من رصد كوكب زحل عن طريق المقراب في سنة 1610، ومنذ ذلك الحين استقطب الكوكب اهتمام محبي علم الفلك والعلماء، فتمّ رصده عدّة مرات تحققت في البعض منها اكتشافات مهمة، كما حصل بتاريخ 20 سبتمبر سنة 2006، عندما التقط مسبار كاسيني هويغنز حلقة جديدة لم تكن مكتشفة قبلاً، تقع خارج حدود الحلقات الرئيسية البرّاقة وبين الحلقتين "ع" و"ي".

وفي شهر يوليو من نفس السنة، التقط ذات المسبار صورة ظهرت فيها الأدلة الأولى على وجود بحيرات هيدروكربونية في القطب الشمالي للقمر تيتان، وقد أكد العلماء صحة هذا الأمر في شهر يناير من عام 2007، وفي شهر مارس من ذات السنة، التقط المسبار صوراً إضافية كشفت النقاب عن بحار هيدروكربونية على سطح ذلك القمر، أكبرها يصل في حجمه لحجم بحر قزوين. كذلك كان المسبار قد ضبط إعصاراً يصل قطره إلى 8,000 كم في القطب الجنوبي لزحل في شهر أكتوبر من سنة 2006.

يظهر زحل بشكل متكرر في الثقافة الميثولوجية البشرية، ففي علم التنجيم يُقال إن زحل هو الكوكب الرئيسي في كوكبة الجدي، ويلعب دوراً كبيراً في التأثير على حظوظ مواليد برج الجدي عند مروره في فلكهم، وكان يُقال أنه يؤثر أيضاً على مواليد برج الدلو. كان للرومان احتفال سنوي يُطلق عليه اسم "ساتورنيا"، يُقام على شرف الإله "ساتورن".

أما عن أبرز التمثيلات الإنسانية لزحل في العصر الحالي: عملية زحل، أو عملية زحل الصغير، التي قام بها الجيش الأحمر خلال الحرب العالمية الثانية على الجبهة الشرقية، وخاض خلالها عدّة معارك في شمال القوقاز ضد الجيش النازي. كذلك هناك بضع تقنيات أطلق عليها مبتكروها تسمية "زحل"، منها سيارات إطلاق الصواريخ الخاصة ببرنامج أبولو الفضائي، وشركة ساتورن المتفرعة عن شركة جنرال موتورز، بالإضافة إلى شركة ساتورن للإلكترونيات، وغيرها.
رصد زحل
زحل هو الكوكب الأبعد عن الشمس من بين الكواكب الخمسة المرئية بسهولة بالعين المجردة من الأرض، والكواكب الأربعة الأخرى هي: عطارد والزهرة والمريخ والمشتري، وأحياناً يمكن رؤية أورانوس بالعين المجردة في سماء داكنة جداً، إضافة إلى الكويكب 4 فيستا. وكان آخر الكواكب المعروفة لعلماء الفلك في وقت مبكر حتى اكتشاف أورانوس في عام 1781. يظهر زحل للعين المجردة في سماء الليل كنقطة مصفرّة لامعة وعادة ما تملك قدرا ظاهريا يتراوح بين +1 إلى 0، وتصل قيمة هذا القدر في حالات أقصى لمعان إلى -0.24. ويأخذ زحل ما يُقارب 29 سنة ونصف ليُتم دورة كاملة حول الشمس. معظم الناس يحتاجون إلى مساعدات ضوئية (مناظير كبيرة) تُكبر بمقدار لا يقل عن 20× لرؤية حلقات زحل بوضوح.

تكون أوضح رؤية لزحل وحلقاته عندما تكون الزاوية بينه وبين الشمس 180 درجة وبالتالي يظهر عكس الشمس في السماء.

زحل عند القدماء
عرف الإنسان كوكب زحل منذ عصور ما قبل التاريخ لإمكانية رؤيته بالعين المجرّدة بسهولة. وقد كان في العصور القديمة أبعد الكواكب الخمسة المعروفة في النظام الشمسي، باستثناء الأرض، وبالتالي كان له خواص رئيسية في الأساطير المختلفة. ورصده علماء الفلك البابليون بصورة منتظمة وقاموا بتسجيل تحركاته. وهو في الأساطير الرومانية القديمة يُمثّل الإله ساتورن، ومنه أخذ الكوكب اسمه في عدد من اللغات اللاتينية والجرمانية، وحسب معتقدات الرومان فساتورن هو إله الزراعة والحصاد. وقد كان الرومان يعتبرون أن ساتورن يُقابل الإله اليوناني كرونوس.

تنص الميثولوجيا الهندوسية على وجود تسعة أجرام فضائية تُعرف باسم نافاجرهاس (بالسنسكريتية: नवग्रह)، يعدّ زحل إحداها ويعرف باسم شاني (بالسنسكريتية: शनि؛ وبالتاميلية: சனி)، وهو من يُحاسب جميع الناس على ما أقدموا عليه من أعمال في الحياة الدنيا، سواء كانت خيّرة أم شريرة. وفي القرن الخامس حدد نص فلكي هندي يحمل عنوان ثريا سيدهانتا قطر كوكب زحل بحوالي 73882 ميل، أي بقيمة أقل بنسبة 1% من القيمة الحقيقة البالغة 74580 ميل.

في حين اعتبر الصينيون واليابانيون القدماء بأن زحل إنما هو نجم للأرض (土星)، وقد استند الفلكيون من هاتين الحضارتين إلى العقيدة الفلسفية التي تقول بأن جميع العناصر الطبيعية تتكون من عناصر الطبيعة الخمسة: النار والتراب والمعدن والخشب والماء.

الرصد التاريخي لكوكب زحل
يقسم تاريخ مراقبة واستكشاف كوكب زحل إلى ثلاث مراحل رئيسية: الأولى منها هي الأرصاد القديمة، والتي كانت مُقتصرة على أدوات بسيطة (بشكل رئيسي العين المجردة) وكانت قبل اختراع المقرابات. أما المرحلة الثانية فكانت باستخدام المقرابات عندما اخترعت أوائل القرن السابع عشر وأخذت بالتطوّر والتحسن. وكانت المرحلة الأخيرة هي زيارة المركبات الفضائية للكوكب، إما عن طريق الدخول في مدار حوله أو التحليق فوقه بواسطة المسابير الفضائية.

كان زحل معروفاً منذ العصور التاريخية القديمة، ويعدّ الفيزيائي الإيطالي جاليليو جاليلي، من الأوائل الذين رصدوه بالمقراب في سنة 1610. كانت الأرصاد الأوليّة لكوكب زحل صعبة بعض الشيء وذلك لأن الأرض تعبر خلال مستوى حلقات زحل في بعض السنين عندما يتحرك في مداره. وبسببها تنتج صورة قليلة الوضوح لكوكب زحل. قام العالم كريستيان هويغنز في عام 1659 باكتشاف حلقة وصفها بأنها "حلقة غير ملاصقة بالكوكب ومائلة عن مستوى مداره"، ومنذئذ اشتهر كوكب زحل بكونه الكوكب الوحيد المحاط بحلقات حتى عام 1977م عندما اكتشفت حلقات رقيقة حول كوكب أورانوس وبعد ذلك بفترة بسيطة حول المشتري ونبتون. وفي عام 1675 اكتشف الفلكي الفرنسي جيوفاني كاسيني أن الحلقة التي رآها هويغنز مقسّمة إلى قسمين متساويين بخطين متساويين بخط معتم، يُسمّى هذا الخط حالياً بحاجز كاسيني. وفي عام 1850م تم اكتشاف حلقة جديدة أقرب إلى الكوكب من سابقتيها وأكثر إعتاماً. كما اكتشف كاسيني أربعة أقمار لزحل في الفترة الممتدة بين عاميّ 1671 و1684 هي: ريا وتثيس وديون وإيابيتوس. وفي عام 1979 اكتشف فلكيون فرنسيون حلقة جديدة أخرى أبعد من سابقاتها عن زحل.

استخدمت مركبة "بيونير 11" في أول زيارة لكوكب زحل في عام 1979، وبعد ذلك تمّ اللجوء إلى مركبات فوياجر 1 وفوياجر 2 ثمّ كاسيني-هويغنز في عام 2004.

الرحلات الفضائية إلى زحل
بيونير 11
أول زيارة لكوكب زحل كانت بواسطة المسبار بيونير 11 في شهر أيلول/سبتمبر من سنة 1979، وقد حلّق على ارتفاع 20000 كيلومتر من السحب العليا للكوكب. وقد تم التقاط صور قليلة الدقة للكوكب ولبعض أقماره. ولم تكن دقة الصور عالية بالقدر الكافي لتحديد معالم السطح بشكل جيد. قام المسبار أيضاً بدراسة الحلقات، وقد أدّى هذا إلى بضعة اكتشافات منها وجود حلقة رقيقة سُميّت "حلقة-ف"، إضافة إلى وجود فجوات مظلمة بين الحلقات تضيء عندما تظهر باتجاه الشمس، أي أن هذه الفجوات ليس فارغة تماماً بل تحتوي بعض المواد. كما قام هذا المسبار بقياس درجة حراراة أكبر أقمار زحل الذي يحمل اسم "تيتان"
فوياجر
زار المسبار فوياجر 1 كوكب زحل في تشرين الثاني/نوفمبر من سنة 1980م، ونجح في إرسال أول صور عالية الدقة للكوكب والحلقات وبعض الأقمار، وقد استطاع أن يلتقط صوراً لتضاريس أسطح العديد من الأقمار لأول مرة. كما قام بتحليق قريب من تيتان أدّى إلى زيادة معرفة الفلكيّين بشكل كبير حول الغلاف الجوي لهذا القمر. وأثبت أيضاً أن أمواج الطيف المرئي لا يُمكنها النّفاذ عبر الغلاف الجويّ لتيتان، ومن ثم لم يستطيعوا آنذاك رؤية أية تضاريس على سطح ذلك القمر أو التعرّف عليها.

وفي شهر آب/أغسطس من سنة 1981، واصل فوياجر 2 دراسة نظام زحل. تم الحصول على المزيد من الصور عن قرب لأقمار زحل، كما عُثر على دلائل تدلّ على وجود تغيرات في غلافه الجوي وحلقاته. ولسوء الحظ، تعطّل محول الكاميرا في المسبار خلال التحليق وتوقف لبضعة أيام، وبالتالي فُقدت بعض الصور التي خطط العلماء للحصول عليها. وقد تم لاحقاً استخدام جاذبية زحل لتوجيه مسار المركبة الفضائية نحو أورانوس.

استطاع هذا المسبار اكتشاف وتأكيد وجود العديد من الأقمار الجديدة بجانب أو داخل الحلقات. كما اكتشف فجوة ماكسويل وفجوة كيلر.

Saturn

Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth.[14][15] It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.[16][17][18] Saturn is named after the Roman god of wealth and agriculture; its astronomical symbol (♄) represents the god's sickle.

Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). This core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's.[19] The outer atmosphere is generally bland and lacking in contrast, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h (1,100 mph; 500 m/s), higher than on Jupiter, but not as high as those on Neptune.[20] In January 2019, astronomers reported that a day on the planet Saturn has been determined to be 10h 33m 38s + 1m 52s
− 1m 19s , based on studies of the planet's C Ring.[8][9]

The planet's most famous feature is its prominent ring system that is composed mostly of ice particles, with a smaller amount of rocky debris and dust. At least 62 moons[21] are known to orbit Saturn, of which 53 are officially named. This does not include the hundreds of moonlets in the rings. Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, although less massive, and is the only moon in the Solar System to have a substantial atmosphere
Saturn is a gas giant because it is predominantly composed of hydrogen and helium. It lacks a definite surface, though it may have a solid core.[23] Saturn's rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator. Its equatorial and polar radii differ by almost 10%: 60,268 km versus 54,364 km.[5] Jupiter, Uranus, and Neptune, the other giant planets in the Solar System, are also oblate but to a lesser extent. The combination of the bulge and rotation rate means that the effective surface gravity along the equator, 8.96 m/s2, is 74% that at the poles and is lower than the surface gravity of Earth. However, the equatorial escape velocity of nearly 36 km/s is much higher than that for Earth.[24]

Saturn is the only planet of the Solar System that is less dense than water—about 30% less.[25] Although Saturn's core is considerably denser than water, the average specific density of the planet is 0.69 g/cm3 due to the atmosphere. Jupiter has 318 times Earth's mass,[26] and Saturn is 95 times Earth's mass.[5] Together, Jupiter and Saturn hold 92% of the total planetary mass in the Solar System.[27]

Internal structure
Despite consisting mostly of hydrogen and helium, most of Saturn's mass is not in the gas phase, because hydrogen becomes a non-ideal liquid when the density is above 0.01 g/cm3, which is reached at a radius containing 99.9% of Saturn's mass. The temperature, pressure, and density inside Saturn all rise steadily toward the core, which causes hydrogen to be a metal in the deeper layers.[27]

Standard planetary models suggest that the interior of Saturn is similar to that of Jupiter, having a small rocky core surrounded by hydrogen and helium with trace amounts of various volatiles.[28] This core is similar in composition to Earth, but more dense. Examination of Saturn's gravitational moment, in combination with physical models of the interior, has allowed constraints to be placed on the mass of Saturn's core. In 2004, scientists estimated that the core must be 9–22 times the mass of Earth,[29][30] which corresponds to a diameter of about 25,000 km.[31] This is surrounded by a thicker liquid metallic hydrogen layer, followed by a liquid layer of helium-saturated molecular hydrogen that gradually transitions to a gas with increasing altitude. The outermost layer spans 1,000 km and consists of gas.[32][33][34]

Saturn has a hot interior, reaching 11,700 °C at its core, and it radiates 2.5 times more energy into space than it receives from the Sun. Jupiter's thermal energy is generated by the Kelvin–Helmholtz mechanism of slow gravitational compression, but such a process alone may not be sufficient to explain heat production for Saturn, because it is less massive. An alternative or additional mechanism may be generation of heat through the "raining out" of droplets of helium deep in Saturn's interior. As the droplets descend through the lower-density hydrogen, the process releases heat by friction and leaves Saturn's outer layers depleted of helium.[35][36] These descending droplets may have accumulated into a helium shell surrounding the core.[28] Rainfalls of diamonds have been suggested to occur within Saturn, as well as in Jupiter[37] and ice giants Uranus and Neptune.[38]

Atmosphere
The outer atmosphere of Saturn contains 96.3% molecular hydrogen and 3.25% helium by volume.[39] The proportion of helium is significantly deficient compared to the abundance of this element in the Sun.[28] The quantity of elements heavier than helium (metallicity) is not known precisely, but the proportions are assumed to match the primordial abundances from the formation of the Solar System. The total mass of these heavier elements is estimated to be 19–31 times the mass of the Earth, with a significant fraction located in Saturn's core region.[40]

Trace amounts of ammonia, acetylene, ethane, propane, phosphine and methane have been detected in Saturn's atmosphere.[41][42][43] The upper clouds are composed of ammonia crystals, while the lower level clouds appear to consist of either ammonium hydrosulfide (NH
4SH) or water.[44] Ultraviolet radiation from the Sun causes methane photolysis in the upper atmosphere, leading to a series of hydrocarbon chemical reactions with the resulting products being carried downward by eddies and diffusion. This photochemical cycle is modulated by Saturn's annual seasonal cycle.[43]

Cloud layers
Saturn's atmosphere exhibits a banded pattern similar to Jupiter's, but Saturn's bands are much fainter and are much wider near the equator. The nomenclature used to describe these bands is the same as on Jupiter. Saturn's finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s. Since then, Earth-based telescopy has improved to the point where regular observations can be made.[45]

The composition of the clouds varies with depth and increasing pressure. In the upper cloud layers, with the temperature in the range 100–160 K and pressures extending between 0.5–2 bar, the clouds consist of ammonia ice. Water ice clouds begin at a level where the pressure is about 2.5 bar and extend down to 9.5 bar, where temperatures range from 185–270 K. Intermixed in this layer is a band of ammonium hydrosulfide ice, lying in the pressure range 3–6 bar with temperatures of 190–235 K. Finally, the lower layers, where pressures are between 10–20 bar and temperatures are 270–330 K, contains a region of water droplets with ammonia in aqueous solution.[46]

Saturn's usually bland atmosphere occasionally exhibits long-lived ovals and other features common on Jupiter. In 1990, the Hubble Space Telescope imaged an enormous white cloud near Saturn's equator that was not present during the Voyager encounters, and in 1994 another smaller storm was observed. The 1990 storm was an example of a Great White Spot, a unique but short-lived phenomenon that occurs once every Saturnian year, roughly every 30 Earth years, around the time of the northern hemisphere's summer solstice.[47] Previous Great White Spots were observed in 1876, 1903, 1933 and 1960, with the 1933 storm being the most famous. If the periodicity is maintained, another storm will occur in about 2020.[48]

The winds on Saturn are the second fastest among the Solar System's planets, after Neptune's. Voyager data indicate peak easterly winds of 500 m/s (1,800 km/h).[49] In images from the Cassini spacecraft during 2007, Saturn's northern hemisphere displayed a bright blue hue, similar to Uranus. The color was most likely caused by Rayleigh scattering.[50] Thermography has shown that Saturn's south pole has a warm polar vortex, the only known example of such a phenomenon in the Solar System.[51] Whereas temperatures on Saturn are normally −185 °C, temperatures on the vortex often reach as high as −122 °C, suspected to be the warmest spot on Saturn.[51]

Post Malone

Austin Richard Post (born July 4, 1995),[2] known professionally as Post Malone, is an American rapper,[10][11][12] singer, songwriter and record producer. He has gained acclaim for blending musical genres including pop, trap and rock,[13] his introspective songwriting, and his laconic vocal style.[14][15][16] Born in Syracuse, New York and raised in Grapevine, Texas, Post first attained recognition in 2015 following the release of his debut single "White Iverson" which peaked in the top 20 on the US Billboard Hot 100.[17] He subsequently earned a recording contract with Republic Records.[18]

Post's debut studio album Stoney (2016) peaked at number four on the US Billboard 200, and was eventually certified triple platinum. Post's second album Beerbongs & Bentleys (2018) debuted at number one on the Billboard 200, and broke several streaming records upon release.[19] The album opened to mixed critical reception and contained the US chart-topping songs "Rockstar" and "Psycho". It was nominated for Album of the Year at the 61st Annual Grammy Awards. In 2018, he collaborated with Swae Lee on the song "Sunflower" for the soundtrack to the film Spider-Man: Into the Spider-Verse, which also reached atop the Hot 100. He then released the song "Wow", which was the first single from his third studio album, Hollywood's Bleeding. It peaked at number two on the Hot 100. He returned in July 2019, releasing the single "Goodbyes", which features Young Thug and debuted at number three on the Hot 100. Post Malone released his third album, Hollywood's Bleeding, on September 6, 2019; it features "Wow", "Goodbyes", "Sunflower", and "Circles", with the latter serving as its third single in August 2019.[20]

As of 2019, Post has sold 60 million records in the US.[21] He has a received a Diamond certification by the Recording Industry Association of America (RIAA) for "Congratulations".[22] He has won two American Music Awards, a Billboard Music Award and a MTV Video Music Award, and has been nominated for four Grammy Awards.
Early life
Austin Richard Post was born on July 4, 1995,[2] in Syracuse, New York.[24][25] Post stated he has Native American ancestry on The Breakfast Club in 2016. He was raised by his father, Rich Post, and his stepmother, Jodie. His father had been a disc jockey in his youth and introduced Post to many different genres of music including hip-hop, country, and rock.[26] When Post was nine years old,[27] he and his family moved to Grapevine, Texas, after his father became the manager of concessions for the Dallas Cowboys.[28][29] Post began to play the guitar and auditioned for the band Crown the Empire in 2010, but was rejected after his guitar strings broke during the audition. He credited his initial interest in learning guitar to the popular video game Guitar Hero.[30]

Post has always had a love for emo music, and appeared for a DJ set at Emo Nite in Los Angeles in June 2017, playing My Chemical Romance at the event.[31] According to Post, his very first foray into professional music began when he was in a heavy metal band.[32] Soon after, he says he transitioned to softer rock as well as hip-hop, before beginning to experiment on FL Studio.[33]

Career
2011–2017: Career beginnings and Stoney
According to Post, he chose "Post Malone" as his stage name when he was 14 or 15.[34] The name was rumored to be a reference to the professional basketball player Karl Malone,[35] but Post later explained that "Post" is his last name, and he used a "rap name generator" to get "Malone".[36] At 16, using Audacity, Post created his first mixtape, Young and After Them Riches.[37] He showed it to some of his classmates at Grapevine High School.[30][38] He was voted "Most Likely to Become Famous" by his classmates as a senior in high school. He worked at a Chicken Express as a teenager.[30]

He enrolled in Tarrant County College but dropped out.[39] After leaving college, Post moved to Los Angeles, California, with his longtime friend Jason Probst, a professional game streamer.[40][41][42]

After moving to LA, Post, Probst, and several other producers and artists formed the music group BLCKVRD and recorded music together.[43] Several members of the group, including Post, moved into a house in San Fernando Valley together. While living in San Fernando Valley, Austin met 1st Down of FKi. He met 1st and Rich from FKi and Rex Kudo who produced several of Post's tracks, including "White Iverson".[24] Post recorded the song two days after writing it.[38] "White Iverson" is, in part, a reference to the professional basketball player Allen Iverson.[44][45][35] In February 2015, upon completion, it was uploaded to Post's SoundCloud account.[46] On July 19, 2015, Post released a music video for "White Iverson". The single received praise from Mac Miller and Wiz Khalifa.[30][47][48] However, the song was notoriously mocked by Earl Sweatshirt
After hitting one million views within a month of releasing "White Iverson", Post quickly garnered attention from record labels.[45] In August 2015, he signed a recording contract with Republic Records.[52][53] Post subsequently worked with a number of prominent rappers such as 50 Cent, Young Thug, and Kanye West, among others.[54][55] In August 2015, he performed at Kylie Jenner's 18th birthday party,[56] where he met Kanye West, who enjoyed his music, leading to him collaborating with Post on his single "Fade" from his album The Life of Pablo.[57] Post later began his friendship with Canadian singer and songwriter Justin Bieber, which led to Post being an opening act for Bieber's Purpose World Tour.[58][59] On April 20, 2016, Post premiered his new single, "Go Flex" on Zane Lowe's Beats 1 show.[60]

On May 12, 2016, he released his first full-length project, a mixtape, titled August 26th,[61] the title of which was a reference to the release date of his debut album. On June 9, 2016, Post made his national television debut on Jimmy Kimmel Live!, performing "Go Flex".[62]

In June 2016, XXL editor-in-chief Vanessa Satten revealed Post Malone was considered for XXL's "2016 Freshmen Class" magazine cover, but she was "told by his camp that he wasn't paying attention to hip hop so much. He was going in more of a rock/pop/country direction."[63] However, Post denied these claims, explaining that his latest mixtape as well as his upcoming album were both hip-hop.[64] In August 2016, Post issued an apology for his album, Stoney, being late.[65] It was available for pre-order on November 4, and was finally released on December 9. Post later went on to call the album "mediocre",[28] despite the success of the single "Congratulations" featuring Quavo, Post's first top-ten song on the Billboard Hot 100, peaking at number eight.[66][67] Stoney also featured the top 100 hits "I Fall Apart", and "Deja Vu", featuring Bieber, with the album later being certified double platinum by the RIAA in October 2017.[68]

2017–2018: Beerbongs & Bentleys
In February 2017, Post revealed the title of his next project, Beerbongs & Bentleys,[69] and was set to be released in December, before eventually being pushed back to 2018.[70] In September, Post released the first single from the album, "Rockstar", featuring 21 Savage. The song peaked at number one on the Billboard Hot 100 and held the spot for eight consecutive weeks,[71] later prompting Rolling Stone to call him "one of the most popular musicians in the country" in 2017. In November, Malone released the official music video for "Rockstar", directed by Emil Nava.[72][73][74][75]

On February 20, 2018, Post previewed his new song with Ty Dolla Sign titled "Psycho."[76] "Psycho" was released on February 23, 2018,[77] and a tour with 21 Savage was announced.[78] The song debuted at number 2 on the Billboard Hot 100, becoming Post's third entry in the top 10.[79] On April 5, 2018, Malone stated that Beerbongs & Bentleys will be released on April 27, 2018.[80] The same day, he also premiered the song "Stay" during the Bud Lite Dive Bar show in Nashville.[81] Upon release, Beerbongs & Bentleys broke the first day streaming records on Spotify, with 78.7 million streams worldwide.[82] It debuted at number one on the Billboard 200 moving 461,000 album-equivalent units in its first week, with 153,000 coming from pure sales. The album was also certified platinum by the RIAA after four days[83] and spawned three top 10 songs and six top 20 songs.[84]

2018–present: Hollywood's Bleeding
In an interview with Billboard in May 2018, Post's manager announced that Post was planning to start his own record label and film production company[85] and Post later won Top Rap Song at the Billboard Music Awards for "Rockstar" featuring 21 Savage.[86] Post confirmed in June 2018 that he was writing his third album,[87] and confirmed that a festival will be taking place, organized by him, titled "Posty Fest" in Dallas, Texas on October 28. Post promised a "blockbuster" lineup with headliners like Travis Scott.[88]

In August, Post broke Michael Jackson's 34-year-old record for most weeks on Billboard's Top R&B and Hip-Hop Albums chart with Stoney reaching its 77th week compared to the 76 weeks that Thriller spent on the chart.[19] A collaboration album with Mac Miller was also teased in August 2018.[89] During his appearance on The Tonight Show Starring Jimmy Fallon, he previewed his song "Sunflower", a collaboration with Swae Lee, from the soundtrack to the film Spider-Man: Into the Spider-Verse.[90][91] In November 2018, it was confirmed Post was recording his third album in his Utah home.[92]

Post has been nominated for 4 awards at the 61st Grammy Awards for his album Beerbongs & Bentleys including awards for Album of the Year and Record of the Year. He performed with Red Hot Chili Peppers at the awards show on February 10, 2019.[93][94] In July 2019, Post Malone released the single "Goodbyes" featuring Young Thug, and also announced the Runaway Tour with Swae Lee as the opener.[95] On August 5, Post shared a snippet of an unreleased track "Circles" on YouTube. He then performed the song at his second annual Bud Light: Dive Bar concert and confirmed that the official song would be released the following week.[96] That same day and on July 25, 2019, at Cheyenne Frontier Days. He released the song on August 30, 2019.[97] He confirmed that his upcoming third studio album will be released on September 6, 2019.[98][99] On August 26, 2019, Post announced on Twitter that his third album is called Hollywood's Bleeding and would be released on September 6, 2019.[100][101]

Musical style
Post's music has been described as a "melting pot of the country, grunge, hip-hop and R&B"[3] and Post himself has been described as versatile.[102] His vocal style has been described as laconic.[14] Jon Caramanica of The New York Times described Post as "an artist who toes the line between singing and rapping, and hip-hop and spooky electric folk".[103] Malone himself has called his music "genre-less".

Post cites Bob Dylan, in whom he became interested around the age of 15, as an influence on his music, calling him "a genius" and "a god" though his music has been called "about as far away from Rock n' Roll as you can get."[104] He called "Subterranean Homesick Blues" the "first rap song". He has a tattoo of Dylan as well.[28] Post also cites Kurt Cobain and Johnny Cash as influences.[105] Post has cited rappers 50 Cent, whom he called a legend,[106] Kanye West and Key! as influences.[107]

Controversies
Post has been called a "culture vulture" multiple times by different publications and on social media[108][109] for "appropriating" African-American culture.[110][111][112] California rapper Lil B wrote on Twitter in October 2017: "Post Malone is slowly turning into a white dude! Lol he's pushing it, give it a few years he gon be full country and hate blacks lol", with Post replying in an interview, claiming that his white skin has been "used against him."[113] In January 2018, Post went on an intoxicated rant against people who describe him as a culture vulture.[114][115] In an interview with GQ several days later, Post said "there's a struggle being a white rapper."[116]

In a November 2017 interview with Polish media outlet NewOnce, Post said that modern hip-hop music lacks "people talking about real shit" and added that "if you're looking to think about life, don't listen to hip-hop."[107][117] He received social media backlash for his comments, including from fellow rappers such as Lil B and Vince Staples.[118][119] Post later appeared in a video on Twitter, saying that the reason for his comments was that it was a "beer-tasting" interview,[120] and going on to say that he loves hip-hop.[121][122] NewOnce, however, denied that claim, stating that Post barely drank at all during the interview.[123]

Personal life
Post currently lives in Los Angeles, California.[124] He also has a multimillion-dollar 13,000-square-foot home in northern Utah.[125] Post's old home in San Fernando Valley, California was robbed on September 1, 2018.[126] Post was in a three year long relationship with Ashlen Diaz, ending in November 2018.[92]

On August 21, 2018, Post boarded a plane leaving Teterboro Airport and was scheduled to land in London Luton Airport. At 10:50 am, the tires blew out on takeoff and the plane was rerouted to Stewart International Airport for an emergency landing.[127] The plane landed safely at 3:50 pm.[128] Once the plane had landed, Post tweeted about the incident, writing "i landed guys. thank you for your prayers. can't believe how many people wished death on me on this website. fuck you. but not today."[129]

Post was involved in a car crash on September 8, 2018. Post's white Rolls-Royce was driving through Santa Monica in the early morning when it collided with another car at 3:30 am. Although no one was severely injured in the incident, several people were treated for minor injuries

Jake Gardiner

Jake William Gardiner (born July 4, 1990) is an American professional ice hockey defenseman who is currently playing for the Carolina Hurricanes of the National Hockey League (NHL). He has also played with for the Toronto Maple Leafs. He was drafted 17th overall by the Anaheim Ducks in the 2008 NHL Entry Draft.
Early life
Gardiner was born in Minnesota to parents Jill and John Gardiner. His father ran a printing business and coached him in peewee.[2]

Playing career
Gardiner played ice hockey at Minnetonka High School.[3] Prior to his senior year at Minnetonka High School, Gardiner switched from forward to defense on the advice of Minnesota State University coach Troy Jutting.[4] In his senior year, Gardiner was named a top-10 finalist for the Mr. Hockey Award and was later drafted by the Anaheim Ducks in the first round, 17th overall, in the 2008 NHL Entry Draft.[4] Despite his high draft place, he then attended the University of Wisconsin–Madison.[5]

In his freshman season with the Badgers, Gardiner was named to the WCHA All-Rookie Team.[6] As an alternate captain with the Badgers during the 2010–11 season, Gardiner was named to the All-WCHA Second Team.[4] While with the Badgers, on February 9, 2011, Anaheim traded Gardiner, along with Joffrey Lupul and a conditional fourth-round draft pick in 2013, to the Toronto Maple Leafs in exchange for defenseman François Beauchemin.[7] Gardiner chose to forgo his senior season with the Badgers and instead signed a three-year entry level contract with the Toronto Maple Leafs
Gardiner started the 2011–12 season with the Leafs, scoring his first career NHL goal on January 24, 2012, against Al Montoya of the New York Islanders.[10] After his rookie campaign where he led rookie defensemen in scoring, Gardiner was named to the NHL All-Rookie Team.[11]

Gardiner started his second season with the Toronto Marlies, due to the NHL Lockout. He posted 31 points in 43 games in the AHL, and then, once the NHL started up, he had 4 assists in 12 games. While playing with the Marlies, Gardiner suffered a concussion on December 8 and was out of the lineup for a month to recover.[12] On May 6, 2013, Gardiner became the first Toronto Maple Leaf to score a home Stanley Cup playoff goal since Mats Sundin scored in a 3–2 loss to the Philadelphia Flyers on May 4, 2004, a span of nine years and two days.[citation needed] He finished the playoffs with points in 6 games.

Gardiner scored a career high 10 goals and 31 points in the 2013-14 season, trailing only Cody Franson in points among Leafs' defenders.[13]

On July 29, 2014, the Leafs signed Gardiner to a five-year, $20.25 million contract extension.[14] The Leafs struggled that season, and Gardiner managed only 4 goals and 24 points in 79 games, 4th among Leafs' defenders.[13]

For the 2015–16 season, the Leafs hired a new head coach, Mike Babcock, and cleared out Dion Phaneuf by the trade deadline. Gardiner had 7 goals and 31 points, second to Morgan Rielly among Leafs' defenders, taking a step forward under a new coach, even though the team lost the scoring presence of Phil Kessel.

In 2016–17, the Leafs became a winning team once again, an especially high scoring one with the addition of scoring phenoms Auston Matthews, William Nylander, and Mitch Marner, among others. Gardiner posted a career high of 43 points, and was a +24, leading all Leafs' defenders in both categories.

During the 2017–18 season, Gardiner recorded his 50th point of the season on April 2, 2018, in a game against the Buffalo Sabres. With his 50th point, and fellow defenceman Morgan Rielly already having 51 points, they became the first two Leafs defensemen with at least 50 points in a season since Tomáš Kaberle and Bryan McCabe did it in 2006–07.[15] Both Gardiner and Rielly ended the regular season with a career high 52 points to help the Leafs to their second consecutive playoff showing,[16] in which they would lose to the Boston Bruins in seven games in the first round.

The following season, Gardiner played in his 500th career NHL game on October 27, 2018, against the Winnipeg Jets. In the game, he scored the tying goal in the third period to help the Leafs defeat the Jets 3–2.[17]

On September 6, 2019, the Carolina Hurricanes signed Gardiner to a 4 year contract with an average annual value of $4.05 million.[18]

International play
After the Leafs failed to make a playoff run in the 2013–14 season, Gardiner joined teammates Nazem Kadri, James Reimer and Morgan Rielly to compete in the 2014 IIHF World Championship. He joined Team USA under coach Peter Laviolette, where the nation lost in the quarter-finals.[19] The following year, Gardiner was again named to Team USA for the 2015 IIHF World Championship, where they placed third.[20]

Personal life
On July 9, 2017, Gardiner married his long-time girlfriend Lucy.[21] In September 2018, Lucy gave birth to their first child, a son.[22]

Gardiner's younger brother Max was selected by the St. Louis Blues in the third round, 74th overall, of the 2010 NHL Entry Draft.[23] He also has a younger sister, Paige, who runs a jewelry business
