Abahanga muri siyanse bo kuri kaminuza ya John Hopkins muri Leta Zunze Ubumwe za Amerika, bakoresheje amakuru yatanzwe na ya ndebakure idasanzwe James Webb maze biga uyu mubumbe wa kure witwa HD 189733 b.<\/p>\n\n\n\n

Ni umubumbe rutura w\u2019ubururu ufite ubunini nk\u2019ubwa Jupiter, iyi iruta inshuro 11 mu bunini uyu mubumbe wacu w\u2019isi.<\/p>\n\n\n\n

Ikirere cy\u2019uriya mubumbe kirimo ibimenyetso by\u2019umwuka wa sulfure d’hydrog\u00e8ne (H\u2082S), iyi ni mol\u00e9cule ubusanzwe itanga kunuka kudasanzwe kw\u2019amagi yaboze ndetse no kunuka kw\u2019imisuzi.<\/p>\n\n\n\n

\u201cIyaba izuru ryawe ryashobora kwinukiriza mu bushyuhe bwa 1,000 \u00b0C, ikirere cy\u2019aho hantu cyakunukira nk\u2019igi ryaboze\u201d, ni ibivugwa na Guangwei Fu, inzobere mu bumenyi bw\u2019isanzure wo kuri kaminuza ya John Hopkins wayoboye ubwo bushakashatsi.<\/p>\n\n\n\n

HD 189733 b iri ku ntera y\u2019imyaka-urumuri (light-years) 64 uvuye ku isi. Abahanga bavuga ko ‘light-years’ imwe ireshya na kilometero tiriyari icyenda (9.000.000.000.000km).<\/p>\n\n\n\n

Abahanga mu by\u2019isanzure bavuga ko uyu mubumbe ari \u201cJupiter ishyushye\u201d iri hafi hashoboka babasha kureba, kandi ari wo wakozwehoubushakashatsi bwinshi mu mibumbe yo hanze y\u2019igaragiye izuba (solar system\/syst\u00e8me solaire), kuva wavumburwa mu 2005, nk\u2019uko Fu abisobanura.<\/p>\n\n\n\n

Bifata iminsi ibiri yo ku isi kugira ngo uyu mubumbe ubashekwizengurukaho. Ubaho ubushyuhe bukabije bugera kuri 1,000 \u00b0C ndetse ugwaho imvura y\u2019amabuye ashashagirana nk’ibirahure (crystals), kandi haba imiyaga igira umuvuduko wa 8,000 km ku isaha.<\/p>\n\n\n\n

“Ntabwo turi gushakayo ubuzima”<\/h2>\n\n\n\n

Kuvumbura \u2018molecule\u2019 ya \u2018sulfure d’hydrog\u00e8ne\u2019 kuri HD 189733 b biri mu kuboneka kwa mbere kwabayeho kwa \u2018sulfure d’hydrog\u00e8ne\u2019 hanze y\u2019imibumbe igaragiye izuba.<\/p>\n\n\n\n

Nubwo \u2018sulfure d’hydrog\u00e8ne\u2019 ari umwe mu myuka isobanuye ko imibumbe ya kure ishobora kubaho ibinyabuzima bitari ibya hano ku isi, abashakashatsi ntabwo barimo gushaka ubuzima kuri uyu mubumbe, kuko ari umubumbe w\u2019imyuka kimwe na Jupiter, kandi urashyushye bikabije.<\/p>\n\n\n\n

Gusa, kuvumburayo \u2018sulfure d’hydrog\u00e8ne\u2019 ni intambwe mu gusobanukirwa ukubaho kw\u2019imibumbe, nk\u2019uko abashakashatsi babivuga.<\/p>\n\n\n\n

Fu agira ati: \u201cNtabwo dushaka ubuzima kuri uriya mubumbe kuko ushyushye cyane, ariko kuvumburayo \u2018sulfure d’hydrog\u00e8ne\u2019 ni ikintu gikomeye mu kumenya uko imibumbe inyuranye ibaho\u201d.<\/p>\n\n\n\n

Uretse kubona \u2018sulfure d’hydrog\u00e8ne\u2019 mu kirere cya HD 189733 b, abahanga muri siyanse banapimye ahantu h\u2019ibanze hava imyuka ya oxyg\u00e8ne na carbone kuri uyu mubumbe, ni ukuvuga: amazi, \u2018dioxyde de carbone\u2019 na \u2018monoxyde de carbone\u2019.<\/p>\n\n\n\n

Fu ati: \u201c \u2018sulfure\u2019 ni ikintu cy\u2019ingenzi mu kubaho kw\u2019ibindi binyabutabire nka carbone, azote, oxyg\u00e8ne na phosphate, abahanga muri siyanse bagomba gushakisha kurushaho kugira ngo bamenye uko imibumbe yirema n\u2019ibiyigize.\u201d<\/p>\n\n\n\n

Ibyuma by\u2019amayobera<\/h2>\n\n\n\n

Abashakashatsi basesenguye kandi imyuka ya m\u00e9thane kuri dans HD 189733 b maze bapima ikigero cy\u2019ibyuma biyirimo.<\/p>\n\n\n\n

Imibumbe minini cyane y\u2019urubura nka Neptune na Uranus, ifite ibyuma byinshi kurusha imibumbe minini cyane y\u2019imyuka nka Jupiter na Saturne, iyi ni nayo iruta iyindi mu igaragiye izuba.<\/p>\n\n\n\n

Kugaragara kw\u2019ibyuma byinshi ku mibumbe ya Neptune na Uranus gusobanuye ko mu kwirema kw\u2019ibanze kw\u2019iyi mibumbe yagize urubura rwinshi, amabuye n\u2019ibindi bintu biremereye ugereranyije n\u2019imyuka nka hydrog\u00e8ne na h\u00e9lium.<\/p>\n\n\n\n

Abahanga muri siyanse ntibarasubanukirwa impamvu y\u2019ibyuma kuri uriya mubumbe w\u2019ubururu, bityo barashaka kumenya niba ibyabaye kuri Neptune cyangwa Jupiter ari nako byagenze ku mibumbe yo hanze y\u2019igaragiye izuba nk\u2019uyu, nk\u2019uko Fu abisobanura.<\/p>\n\n\n\n

Ati: \u201cUbu rero dufite ibipimo bishya byerekana ko mu by\u2019ukuri, kuba hari ibyuma byinshi kuri uriya mubumbe [HD 189733 b] ari ikintu cy\u2019ingenzi cyo kwiga\u201d.<\/p>\n\n\n\n

Indebakure y\u2019impinduramatwara<\/h2>\n\n\n\n

Indebakure (Telescop) James Webb yafunguye idirishya rishya mu gusesengura ibinyabutabire bigize imibumbe ya kure cyane yacu, ituma abahanga mu isanzure bamenya byinshi ku nkomoko yayo.<\/p>\n\n\n\n

Fu ati: \u201cMu by\u2019ukuri [James Webb ] yahinduye ubumenyi bw\u2019isanzure. Yakoze ibyo yari yitezweho ndetse hamwe na hamwe yarengeje ibyari biyitezweho.\u201d<\/p>\n\n\n\n

Mu mezi ari imbere, ikipe ya Fu irateganya gukorashe amakuru (data) y\u2019iriya ndebakure mu gushakisha umwuka wa \u2018sulfur\u2019 ku yindi mibumbe yo hanze y\u2019igaragiye izuba, kugira ngo bamenye uko yabayeho bagereranyije n\u2019inyenyeri nkuru igaragiye.
