TRAPPIST-1: Perbedaan antara revisi

Pada tahun 2015, tim astronom yang dipimpin oleh [[Michaël Gillon]] di [[Universitas Liège]], [[Belgia]] menggunakan [[fotometri transit]] bersama dengan ''Transiting Planets and Planetesimals Small Telescope'' ([[TRAPPIST]]) di [[Observatorium La Silla]] di Chili untuk menemukan tiga planet seukuran Bumi yang sedang mengorbit bintang katai.<ref name="eso.org"/><ref name="Guardian">{{cite web|url=https://www.theguardian.com/science/2016/may/02/could-these-newly-discovered-planets-orbiting-an-ultracool-dwarf-host-life|title=Could these newly-discovered planets orbiting an ultracool dwarf host life?|work=[[The Guardian]]|date=2 May 2016}}</ref><ref name="eso.org"/><ref>{{Cite web|url= http://www.popularmechanics.com/space/deep-space/a20671/three-planets-life-outside-the-solar-system/ |title=Three New Planets Are the Best Bets for Life |work=[[Popular Mechanics]] |date=2 May 2016 |access-date=2 May 2016}}</ref> Tanggal 22 Februari 2017, para ahli astronomi mengumumkan empat [[eksoplanet]] tambahan sekitar TRAPPIST-1. Selain TRAPPIST, pekerjaan ini memanfaatkan antara lain [[Very Large Telescope]] di Paranal dan [[Teleskop luar angkasa Spitzer]] NASA, dan menemukan total jumlah planet menjadi tujuh, di mana tiga di antaranya dianggap berada dalam [[zona laik huni]].<ref name="SpaceRef">{{cite web |url=http://spaceref.com/astronomy/temperate-earth-sized-planets-found-in-extraordinarily-rich-planetary-system-trappist-1.html |title=Temperate Earth-Sized Planets Found in Extraordinarily Rich Planetary System TRAPPIST-1 |date=22 February 2017 |author= |publisher=SpaceRef |accessdate=11 February 2017 }}</ref><ref>{{Cite press release|url=https://exoplanets.nasa.gov/news/1419/nasa-telescope-reveals-largest-batch-of-earth-size-habitable-zone-planets-around-single-star/|title=NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star|newspaper=Exoplanet Exploration: Planets Beyond our Solar System|access-date=22 February 2017}}</ref> Yang lainnya juga mungkin dipercaya laik dihuni (memiliki air cair di suatu tempat di permukaannya).<ref>{{cite web |url=http://spaceref.com/astronomy/temperate-earth-sized-planets-found-in-extraordinarily-rich-planetary-system-trappist-1.html |title=Temperate Earth-Sized Planets Found in Extraordinarily Rich Planetary System TRAPPIST-1 |date=22 February 2017 |author= |publishername="SpaceRef |accessdate=11 February 2017 }}<"/ref><ref>{{Cite news|url= https://exoplanets.nasa.gov/news/1419/nasa-telescope-reveals-largest-batch-of-earth-size-habitable-zone-planets-around-single-star/|title= NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star |newspaper= Exoplanet Exploration: Planets Beyond our Solar System |access-date= 22 February 2017 |publisher= [[NASA]]}}</ref>

Sistem ini kemudian dipelajari oleh sebuah tim di [[Universitas Liège]], yang membuat observasi awal mereka menggunakan ''Transiting Planets and Planetesimals Small Telescope–South'' dari bulan September hingga Desember 2015 dan mengumumkan temuan mereka dalam edisi Mei 2016 Jurnal ''[[Nature]]''.<ref name = "GuardianGillon2016" /><ref name = "Gillon2016Guardian" />[[Akronim]] teleskop robotik dari TRAPPIST menekankan bahwa proyek ini berasal dari Belgia, menunjukkan seperti halnya [[ordo keagamaan]] kontemplatif dari para [[Trapis]] (para astronom merayakan penemuan mereka dengan satu ronde [[bir Trapis]] kontemplatif,<ref>{{cite web|url=http://foreignpolicy.com/2017/02/22/new-terrestrial-planets-discovered-by-international-scientists-international-collaboration-maybe-theres-some-aliens/|title=News So Foreign It’s Out of This World: Scientists Discover Seven New Potentially Habitable Planets|last=Gramer|first=Robbie|date=22 February 2017|publisher=[[Foreign Policy]]}}</ref> yang mereka junjung tinggi).<ref>{{cite web | url = http://www.eso.org/public/news/eso1023/ | title = New National Telescope at La Silla—TRAPPIST to Scout the Sky and Uncover Exoplanets and Comets (eso1023 — Organisation Release) | date = 8 June 2010 | website = www.eso.org | publisher = ESO | accessdate = 4 January 2015}}</ref> Karena bintang yang dikitari eksoplanet pertama ditemukan dengan teleskop ini, maka para penemu menamakannya "TRAPPIST-1".
