Lub European Southern Observatory (ESO) tau tshaj tawm txog kev ua tiav astronomy-npaj: cov kws tshawb fawb tau ntes thawj cov duab ncaj qha ntawm lub qhov dub loj heev thiab nws "duab ntxoov ntxoo" (hauv daim duab peb sab).
Kev tshawb fawb tau ua tiav siv Event Horizon Telescope (EHT), lub ntiaj teb-teev kav hlau txais xov array ntawm yim hauv av hauv xov tooj cua telescopes. Cov no yog, tshwj xeeb tshaj yog, ALMA, APEX complexes, 30-meter IRAM telescope, James Clerk Maxwell telescope, Alfonso Serrano Loj Millimeter Telescope, Submillimeter Array, Submillimeter Telescope thiab South Ncej Telescope.
Cov kws tshaj lij tau tswj kom tau txais cov duab ntawm lub qhov dub ntawm qhov chaw ntawm lub galaxy loj heev Messier 87 nyob rau hauv lub constellation Virgo. Cov duab thaij duab, nrog rau qhov loj ntawm 6,5 billion hnub ci hnub ci, nyob ntawm qhov deb ntawm kwv yees li 55 lab lub teeb xyoo ntawm peb.
Siv ntau yam kev ntsuas ntsuas thiab ntsuas cov tswv yim, lawv tau nthuav tawm lub nplhaib zoo li tus qauv nrog thaj chaw tsaus ntuj - "duab ntxoov ntxoo" ntawm lub qhov dub. Lub "duab ntxoov ntxoo" yog qhov ze tshaj plaws tau kwv yees rau cov duab ntawm lub qhov dub nws tus kheej, ib qho khoom tsaus nti uas tsis tso tawm qhov kaj.
Nws yuav tsum raug sau tseg tias qhov dub muaj qhov cuam tshuam loj rau lawv qhov chaw nyob ib puag ncig, deforming qhov chaw-lub sij hawm thiab cua sov qhov teeb meem nyob ib puag ncig rau qhov kub thiab txias.
“Peb tau txais thawj daim duab ntawm lub qhov dub. Qhov no yog qhov ua tiav kev tshawb fawb ntawm qhov tseem ceeb heev, uas ua rau muaj kev siv zog ntawm pab pawg ntau dua 200 tus kws tshawb fawb, "cov kws tshawb fawb hais.
