Imbali yeplanethi ngokufumanisa i-Exoplanet encinci.
Izazi ngeenkwenkwezi zaseUnited States ziye zafumanisa i-exoplanet, ijikeleza enye yezona nkwenkwezi ziqaqambileyo; ukuqalisa umbono wendlela imizimba yeplanethi enokuthi yakheke ngayo. Kuthiwa i-exoplanet sisijikelezi-langa esijikeleza inkwenkwezi eyahlukileyo kweyethu, ingeyiyo eyesijikelezi-langa sethu.
Uphononongo lwenziwe yi-Astrophysical Journal Letters, owathiya iplanethi i-DS Tuc Ab, ngelixa inkwenkwezi ichazwa njengomkhosi; Esi sijikelezi-langa sineminyaka emalunga nezigidi ezingama-45 ubudala, oko kukuthi, ngexesha leplanethi sithathwa njengesandulelayo.
Ngokutsho kwabaphandi kwiKholeji yaseDartmouth: i-exoplanet ayisakhuli. Nangona kunjalo, ebuncinaneni bayo isenamava otshintsho olufana nokulahlekelwa yigesi ye-atmospheric ngenxa yemitha evela kwinkwenkwezi. Kuthiwa xa iiplanethi zizalwa, zidla ngokuba zikhulu kwaye ngokuthe ngcembe ziyancipha ubukhulu, zibandezeleka kukuphola kunye nokulahleka komoya.
Iimpawu ze-Exoplanet 'DS Tuc Ab'.
Imi kumgama weminyaka eyi-150 yokukhanya ukusuka eMhlabeni. Inamalanga amabini kwaye i-orbit yayo ijikeleze inkwenkwezi yayo ephambili kwiintsuku nje ezisi-8. Ubungakanani bayo buphindwe ka-6 ubukhulu kunoMhlaba, bufana neSaturn kunye neNeptune, kwaye ingaba nokwakheka okufanayo nabo.
Kufuneka kuqatshelwe ukuba iiplanethi zinokuthatha izigidi okanye iibhiliyoni zeminyaka ukufikelela ngokupheleleyo ekuvuthweni. Ngoko injongo yabaphandi kukukhangela izijikelezi-langa ezijikeleze iinkwenkwezi eziselula ukuze bazi nokuqonda indaleko yazo.
Iingxelo ze Elizabeth Newton yayi:
I-TESS yisathelayithi eyasungulwa ngo-Aprili 18, 2018, iya kuba nomsebenzi wokuhlola ngaphezu kweenkwenkwezi ze-200.000 ezijikeleza ilanga ekukhangeleni ii-exoplanets, kuquka ezo zinokuthi zixhase ubomi.
Iqela leNewton linethemba lokuqonda ukubaleka kwe-atmospheric kunye nokuvela kwe-atmospheric, zombini ezinokuthi ziqikelele ikamva le-exoplanet kwiminyaka embalwa ezayo yezigidi, kunye nokuba oku kuzichaphazela njani ezinye iiplanethi.
