Telesgop Event Horizon
Mae Telesgop Event Horizon yn delesgop arae fawr sy'n cynnwys rhwydwaith byd-eang o delesgopau radio. Nod y prosiect yw arsylwi ar yr amgylchedd dyllau du goranferthol, gyda chydraniad onglog yn ddigon uchel i ddatrys strwythurau ar raddfa maint event horizon y twll du. Ymysg y targedau arsylwadol y prosiect yw ddau dwll du gyda'r maint onglog mwyaf: M87* yng nghanol yr alaeth hirgylchol goranferthol Messier 87, a Sagittarius A * yng nghanol y Llwybr Llaethog. [4]
Cyhoeddwyd y delwedd gyntaf o twll du, yr un goranferthol yng nghanol galaeth Messier 87, gan y Cydweithrediad EHT ar Ebrill 10, 2019. [5] [4]
