We are literally going to get our first ever image of Sagittarius A* (the supermassive black hole at the center of the milky way) tomorrow and I'm so fucking excited to see that blurry image omg

By the way, Sagittarius A* is pronounced Sagittarius A Star if you want to talk about it out loud, but it is NOT a star at all.

Sagittarius A* is not currently considered to be an AGN (active galactic nucleus) however it IS still feeding on gas and dust that spirals into it from the interstellar medium in the central bar of the Milky Way, and even from some gas from the solar wind of the 30 or so stars that directly orbit it in a tight cluster.

HOWEVER the REALLY cool thing about black holes is that LIGHT can orbit them!!! Not stabley of course, eventually the light will either find itself on an inwards trajectory or an outwards one. If you were able to stand in this zone, you'd be able to see the back of your own head looking forward because that would just be a valid geodesic in the local geometry. There's a sphere of orbiting light around that black hole!


@starwall is it weird that i knew about this bc of a greg egan story (planck dive),
