Hubble Telescope Kev Tshawb Fawb Qhia Cov Qhov Dub tuaj yeem pab tsim lub hnub qub

Kev tshawb fawb tsis ntev los no raws li Hubble Space Telescope tshawb pom tau pom tias qhov dub tuaj yeem tawm tsam lawv txhua lub sijhawm nqus dej thiab tuaj yeem pab tsim. Cov kev tshawb fawb tau pom ib lub qhov dub loj heev ntawm qhov chaw nruab nrab ntawm lub dwarf galaxy, qee qhov 30 lab lub teeb xyoo deb, tsim cov hnub qub es tsis nqos nws. Lub qhov dub tau pom meej tias ua rau muaj cua daj cua dub ntawm kev tsim lub hnub qub tshiab tshwm sim hauv Henize 2-10 galaxy nyob rau yav qab teb hnub qub Pyxis, NASA tau hais.

Feem ntau dag ntawm qhov chaw ntawm cov galaxies loj xws li peb li, Milky Way, qhov dub tau pom zoo rau kev tiv thaiv lub hnub qub tsim, tsis txhawb nws. Tab sis qhov no ib lab lub hnub ci loj lub qhov dub yog ua rau muaj ntau lub hnub qub tsim. NASA tau hais tias lub me me Henize 2-10 galaxy yog lub hauv paus ntawm kev sib cav ntawm cov kws hnub qub kaum xyoo dhau los. Cov lus nug tom qab ntawd, yog seb cov galaxies dwarf puas tuaj yeem muaj qhov dub qhov sib npaug rau cov behemoths pom hauv cov galaxies loj dua. Qhov kev tshawb pom tshiab no qhia tau tias Henize 2-10 tsuas muaj ib feem kaum ntawm cov hnub qub pom hauv Milky Way.

NASA tau hais hauv a blog tshaj tawm tias cov kws tshawb fawb tau luam tawm lawv cov kev soj ntsuam nyob rau hauv ib daim ntawv lub lim tiam no nyob rau hauv Nature Journal. "Txij thaum pib, kuv paub ib yam dab tsi txawv txawv thiab tshwj xeeb tau tshwm sim hauv Henize 2-10. Thiab, tam sim no, Hubble tau muab cov duab meej meej ntawm kev sib txuas ntawm lub qhov dub thiab thaj chaw uas nyob sib ze uas tsim lub hnub qub nyob hauv 230 lub teeb-xyoo los ntawm lub qhov dub, "said Amy Reines, tus thawj xibfwb ntawm kev tshawb fawb Hubble tshiab.

Lub Hubble telescope yog ib qhov project sib koom ntawm NASA thiab ESA. Tau ua haujlwm tau 30 xyoo ntev, Hubble tau teeb tsa los hloov los ntawm James Webb Space Telescope muaj zog dua thaum lub caij ntuj sov xyoo no.
