Umlando wamaplanethi ngokutholakala kwe-Exoplanet encane.
Izazi zezinkanyezi ezivela e-United States zithole i-exoplanet, izungeza enye yezinkanyezi eziqhakazile kakhulu; ukuqala umbono wokuthi imizimba yamaplanethi ingakhiwa kanjani. Kuthiwa i-exoplanet yiplanethi ezungeza inkanyezi okungeyona eyethu, okungeyona eyesimiso sethu sonozungezilanga.
Ucwaningo lwenziwe yi-The Astrophysical Journal Letters, eyaqamba iplanethi i-DS Tuc Ab, ngenkathi lesi sihlabani sichazwa njengosokhaya; Le planethi icishe ibe neminyaka eyizigidi ezingama-45 ubudala, okungukuthi, ngesikhathi samaplanethi kubhekwa njenge-preadolescent.
Ngokwabacwaningi baseDartmouth College: I-exoplanet ayisakhuli. Kodwa-ke, ebusheni bakhe usabhekana nezinguquko ezifana nokulahleka kwegesi yasemkhathini ngenxa yemisebe evela enkanyezini. Kuthiwa lapho kuzalwa amaplanethi, ngokuvamile, makhulu futhi kancane kancane alahlekelwe usayizi, ahlushwa ukuphola nokulahleka komoya.
Izici ze-Exoplanet 'DS Tuc Ab'.
Itholakala ebangeni eliyiminyaka eyi-150 yokukhanya ukusuka eMhlabeni. Inamalanga amabili futhi umzila wayo wenziwa uzungeze inkanyezi yawo enkulu ngezinsuku eziyi-8 nje kuphela. Ubukhulu bayo buphindwe kayisithupha kunalobo bomhlaba, obufana neSaturn neNeptune, futhi bungaba nokwakheka okufana nalokhu.
Kumele kuqashelwe ukuthi amaplanethi angathatha izigidi ngisho nezigidigidi zeminyaka ukufinyelela ngokugcwele ekuvuthweni. Ngakho-ke inhloso yabaphenyi ukucinga amaplanethi azungeze izinkanyezi ezincane ukuze azi futhi aqonde ukuziphendukela kwazo.
Izitatimende ze Elisabeth newton Babe:
I-TESS yisathelayithi eyethulwe ngo-Ephreli 18, 2018, izonikwa umsebenzi wokuhlola izinkanyezi ezingaphezu kwezingu-200.000 XNUMX ezizungeze ilanga zithungatha ama-exoplanet, kufaka phakathi lawo angahle asekele impilo.
INewton Group inethemba lokuthi izokuqonda ukuphunyuka emkhathini kanye nokuhwamuka okuvela emkhathini, kokubili okungabikezela ikusasa le-exoplanet eminyakeni eyizigidi ezimbalwa ezizayo, nokuthi lokhu kungenzeka ukuthi kuthinte kanjani amanye amaplanethi.
