A black hole’s “surface” is its event horizon. This boundary defines where you’d have to go faster than light – so much faster than anything can go – to escape the black hole. 2/6pic.twitter.com/wN0JtTPSi6

Want to get up to speed on black holes? We’ve got you covered! A black hole is an object so dense that not even light can escape it. #BlackHoleWeek

Two main types of black holes have been extensively observed — stellar-mass and supermassive. The type depends on how much stuff is crammed inside. Tens of times our Sun’s mass for a stellar-mass one; millions to billions for a supermassive one! 3/6pic.twitter.com/S82rcoC9R9

Stellar-mass black holes form when a huge star — with at least 20 times the mass of our Sun — runs out of fuel. It collapses under its own weight and leaves behind a crushed remnant — a black hole.

Supermassive black holes reside at the centers of most (and maybe all) large galaxies.
Scientists are still trying to figure out where they come from. 
But we do know that they existed in the very earliest days of a galaxy’s lifetime. 5/6pic.twitter.com/APncyjXy2gShow this thread -
There *should* be a class of black hole somewhere between the stellar and supermassive ones. While some evidence of these “intermediate mass” black holes has been found, they seem to be more shy than the others! 6/6pic.twitter.com/2WTsmDU6X0
