<prompt> Fingqa isihloko: Ngokwesazi esithile, amaplanethi azulazula emkhathini, engaxhunyiwe kunoma iyiphi inkanyezi noma isimiso sonozungezilanga, kungenzeka ajwayelekile kakhulu kunalokho obekucatshangwa ngaphambili. Amaplanethi kunzima ukuwathola ngoba, ngaphandle kokuzungeza inkanyezi, akhanyisa ukukhanya okuncane kakhulu. Kodwa sekutholakale ezingu - 50 eminyakeni engu - 15 edlule, okwenza abanye basikisele ukuthi kungenzeka ziningi endaweni yonke. U-Ashley Yeager weScience News uye wachaza ukuthi amaplanethi ahamba yodwa umbono womculi ubonisiwe angase abe yinto evamile. Lokhu kubangelwa izindawo eziningi zothuli negesi kunalokho esasikucabanga. Amaplanethi abaama-roguelapho ephonswa ngaphandle noma akha ngokwawo futhi cishe angu-50 atholakele eminyakeni engu-15 edlule. Ukuthi kungenzeka yini ukuba la maplanethi azulazulayo avamile kwaxoxwa ngakho esihlokweni sika-Ashley Yeager seScience News. Amaplanethi angama-rogue, noma amaplanethi aphakathi kwezinkanyezi, ayizinto ezisemaplanethini ezakhiwa ngokwazo noma zaxoshwa esimisweni. Ngokuvamile i - brown dwarf ibhekwa ngokuthi isixhumanisi esilahlekile phakathi kwezinkanyezi namaplanethi. Zinkulu kakhulu ukuba zingahlukaniswa njengamaplanethi eqiniso, kodwa zincane kakhulu ukuba zingase ziqalise ukuhlangana kwamandla enuzi ezinhliziyweni zazo futhi zihlukaniswe njengezinkanyezi. Lapho umzimba wasezulwini uqala ukwakheka, ubukhulu bawo buyonquma ukuthi uba luhlobo luni lwento. Njengoba inkanyezi ivela esibhakabhakeni segesi, umnyombo wayo uba mkhulu kangangokuba i-hydrogen ihlangana ne-helium. Ngakolunye uhlangothi, iplanethi ihlangana nengqikithi encane engekho mkhulu ngokwanele ukuba ibe nenhlanganisela yenuzi enkabeni yayo. Izibankwa ezinsundu ziphakathi nendawo. Ubukhulu bawo busemkhatsini wesigebenga segesi esifana neJupiter nenkanyezi encane. Phakathi naleso sikhathi, isisindo sazo singase sibe noma yini ephakathi kokuphindwe izikhathi ezingu - 15 kuya kwezingu - 75 kwesikaJupiter. Lokhu akwanele ukusekela ukuhlangana kodwa, ngenxa yobukhulu bazo, lokhu kuye kwaholela izazi zezinkanyezi ukuba zibize ama - brown dwarf ngokuthi izinkanyezi ezihlulekile. Njengoba zingakhiqizi ukukhanya okuningi kucatshangwa ukuthi kungase kube nezinkanyezi ezincane ezinsundu ezizulazulayo emthaleni zilindele ukutholakala. Nokho, ukuthi ziningi kangakanani endaweni yonke kuye kwabangela impikiswano ethile. Kodwa uNksz. Yeager wachaza ukuthi lokho okubizwa ngokuthi ama-globulettes - izindawo zothuli negesi ezingakha amaplanethi - kungenzeka...  <response>: U-Ashley Yeager we-Science News wachaza ukuthi amaplanethi anomuntu oyedwa kungenzeka ajwayelekile. Lokhu kubangelwa izindawo eziningi zothuli negesi kunalokho esasikucabanga. Amaplanethi abaizihlubukilapho ephonswa ngaphandle noma evele ngokwawo. Eminyakeni engu - 15 edlule kuye kwatholakala cishe angu - 50. Kodwa njengoba zingazungezi inkanyezi ziveza ukukhanya okuncane futhi kunzima ukuzithola.
