“If this monster was at the center of the Milky Way it would likely make life on Earth impossible with the huge amounts of x-rays emanating from it,” said Christian Wolf, with the Australian National University (ANU) Research School of Astronomy and Astrophysics who made the momentous detection in 2018. “It would appear 10 times brighter than a full moon, an incredibly bright pin-point star that would almost wash out all of the stars in the sky. It’s probably 10,000 times brighter than the galaxy it lives in.” So bright, that it if we were approaching the galaxy in a starship, the object would so blind our view that we could not see the galaxy itself.
This black hole is growing so rapidly that it’s as luminous as 700 trillion suns, shining thousands of times more brightly than an entire galaxy due to all of the gases it sucks in daily that cause lots of friction and heat. How this drainpipe into eternity grew to such mass so early after the Big Bang is a profound puzzle for physics.
