Iqembu lezazi zezinkanyezi ngaphansi kwe-Massachusetts Institute of Technology lishicilelwe , lapho amemezele khona impumelelo yakamuva yomkhankaso omusha wokusesha amaplanethi angaphandle kwesimiso sonozungezilanga. Transiting Exoplanet Survey Satellite (TES) orbital telescope, Ngo-April 18, 2018, wathola into encane kunazo zonke emsebenzini wakhe omfushane wokucwaninga - cishe iplanethi enamatshe elingana noMhlaba wethu.
I-exoplanet HD 21749c izungeza inkanyezi HD 8 esikhathini esingangezinsuku eziyi-21749. Uhlelo lwe-HD 21749 lukude ngeminyaka yokukhanya engama-53 ukusuka kithi. Inkanyezi ibamba cishe u-80% wesisindo seLanga. Ukuzungeza kweplanethi okufushane okuzungeza inkanyezi yasekhaya kusho ukuthi izinga lokushisa elingaphezulu kwalo lingadlula ama-degree Celsius angu-450. Ekuqondeni kwethu, ukuphila esitsheni esishisayo esinjalo akunakwenzeka. Kodwa lokhu akuphazamisi impumelelo ye-TESS. Amasu okusesha namathuluzi azothuthuka, futhi izazi zezinkanyezi zilindele ukuthola inqwaba yama-exoplanets endaweni enethezekile ngokombono wempilo yasemhlabeni.
Kufanele kushiwo ukuthi i-Kepler orbital telescope ithole ama-exoplanets angu-2662 phakathi neminyaka eminingi yokusebenza, amaningi awo angaba ubukhulu boMhlaba. Injongo ye-TESS yehlukile. Isibonakude se-TESS sihlola izinkanyezi eziseduze futhi, kanye nemishini esekelwe phansi e-Chile (Planet Finder Spectrograph, PFS), yenza kube nokwenzeka ukunquma ubukhulu kanye nokwakheka komkhathi wama-exoplanets ngezinga elithile lokunemba.
Eminyakeni emibili, inhloso ye-TESS ilindele ukufunda ngezinhlelo zezinkanyezi ezingaphezu kuka-200. Ososayensi balindele ukuthi lokhu kuzosiza ukuthola ama-exoplanets angaphezu kwama-000. Isathelayithi ivala ngaphezu kwama-50% esibhakabhakeni phakathi nezinsuku eziyi-90. Ngendlela, enye i-exoplanet yatholwa ohlelweni lwe-HD 13,5 - HD 21749b. Kodwa le ndikimba yasezulwini ingeyesigaba "se-sub-Neptune", futhi i-TESS isivele ithole izinto ezinjalo ezimbalwa.
