This Little Red Dot Is Sign Of Impossibly Huge Black Hole
Scientists have discovered a black hole with about 12 billion times the mass of our sun. But what does that really mean?By Sebastian Martinez | February 26, 2015
This little red dot astronomers have discovered is actually the quasar from a black hole approximately 12 billion times the mass of our sun. That's pretty hard to take in on its own, so allow us to help.
First off: No, it doesn't pose a threat to us. It's so far away that the light from the quasar — luminous spirals of gas going into the black hole — takes billions of years to get to us, and it's moving away from us as the universe expands. (Video via European Southern Observatory)
With that out of the way, we have to do some stretching to understand what something 12 billion times more massive than our sun actually means.
