Muri Gicurasi 2020, ku butaka bw'ubutayu bwa Sahara, wasangaga meteorite idasanzwe, yabonetse agace katagize umwanya wo gushinga umubumbe. Byemezwa ko ibuye rito rirenze miliyari zirenga miliyoni 4.6 zirenze, ni ukuvuga ko aruta igihugu. Abashakashatsi baracyafite uruhare mu kwiga ikintu cyabonetse kandi bizera ko bishobora kwerekana ibintu byinshi bishimishije bijyanye n'imibumbe y'izuba. Mu rwego rw'iyi ngingo, ndasaba kumenya icyo abahanga mu bya siyazi bazi ko Meteorite idasanzwe kandi impamvu umubumbe, igice ariho, kandi ntigishobora gukora neza. Birakwiye gutangiza nukuntu ikintu cyabonetse kidakozwe muburyo bwinshi bwumukungugu n'amabuye, nka meteorite nyinshi. Meteorite ifite inkomoko yibirunga, ni ukuvuga bivuga icyiciro cya Ahondrites, kubyerekeye ubusanzwe nabivuze.
Meteorite idasanzwe mu butayu bwa Sahara
Nk'uko byatangajwe na siyanse Edition, uwasanze Meteorite yahawe izina Erg Chech 002 (EC 002). Yabonetse mu kilo nini y'imyaka 32-y'inzu, ku butaka bw'ubutayu bwa Sandy cya Erg-cheki mu burengerazuba bwa Sahara. Abahanga bahise basobanukirwa ko bakora ikintu kidasanzwe kandi gake cyane. Mubisanzwe, ibyo bita meteorite ya chostertiote biragwa hasi, bigizwe na chondrov - imiterere yuburyo bufite diameter itarenze milimetero itarenze 1 milimetero. Kandi meteorite yabonetse yerekeza kuri Ahotarta, nta Chondrov ikubiyemo. Byemezwa ko Ahondrites yambuwe imishinga izengurutse nkibisubizo byo gushonga, mubisanzwe bibaho mugihe cyibirunga.
Abahanga bemeza ko Meteorite ari muri protoplanets. Iri ni ryo zina ry'umubumbe mu byiciro byambere byabayeho, bimaze gutsinda icyiciro cyimbere cyo gushonga. Ibi bigaragazwa n'imyaka ya Meteorite - isesengura ryerekanye ko ryashinzwe imyaka 4,6 ishize. Kugereranya, imyaka yisi yagereranijwe imyaka miriyari 4.5. Ni ukuvuga, Meteorite yavutse kare kare kuruta umubumbe wacu kandi kubwibyo. Yamaze imyaka miriyari, yanyuze mu kayira k'izuba kugeza igihe arangiye, ataguye mu karere ka Sahara.
Nk'uko abashakashatsi bavuga ko Meteorite ari ibintu bidasanzwe kandi byingenzi mu muryango wa siyansi. Kandi muri rusange, amahirwe yo kuvumbura ahondrite kuva mubumenyi ni muto cyane. Ububiko bwa Meteorin bull, aho amakuru aturuka ku bantu bose agwa ku isi, mu mateka yose yo kwitegereza, abashakashatsi basanze Meteori gusa. Amakuru amwe avuga ko Ahondrites ari ubwoko busanzwe bwa Meteori, ariko snag ni uko bidashoboka kubabona nkibisabwa nkuko nshaka.
Soma kandi: Ni bangahe Meteorite yatwaye kandi aho babagura?
Iherezo rya protoplanet
Ku bijyanye n'impamvu Protoplaneta itigeze kuvuka, abahanga bafite igitekerezo kimwe. Aroroshye kandi avuga ko ikintu cyo mwijuru cyarasenyutse kandi gihinduka umukungugu. Birashoboka kandi ko protoplanet yahindutse igice kinini. Ibishishwa bya bark bigizwe nibikoresho byitwa Andeetit. Ifite ishingiro ry'ibirimo byinshi bya Silica n'abahanga bemeza ko ubu kubona promoplace bivuye mu bikoresho biragoye cyane. Kandi byose kuko benshi muribo bazimiye, kandi batabaye benshi rwose.
Muri rusange, protofebrables iri mubintu byumwanya wamayobera. Muri 2016, abashakashatsi bashyize imbere ibitekerezo bitinyutse ko imwe muri protoplanets rimwe na rimwe yahuye n'ukwezi. Ikigaragara ni uko kuri satelite yumubumbe wacu habaye ikiraku kinini, kizwi nkinyanja yimvura. Diameter yayo ahwanye na kilometero 1123, biragaragara neza kuva hasi. Kuva kera, abahanga bizeye ko iyi mvururu yahagurutse kubera kugongana na meteorite. Ariko abahanga mubanyamerika ntibakuraho ko igihe kinini hamwe na satelite, ikintu gisa na protoplanet igaragara. Urashobora gusoma byinshi kuriyi nyigisho muri ibi bikoresho.
Niba ushaka kumenya byinshi kuri Meteorite, ndasaba kwimuka kuriyi link hanyuma umenye ibyabo byose byingenzi. Muri iyo ngingo, navuze ubwoko bwa Meteori byacitsemo ibice, aho bashobora kuboneka ndetse no kubigurisha. Nakoze kandi ku nsanganyamatsiko ya Meteori y'ibinyoma na magendu yabo. Muri rusange, byahindutse ibintu birambuye cyane, birashimishije gusoma!
