Astronomy Tuesday

I haven't posted one of these in a while, but I couldn't resist this image.

Sagittarius A (usually written as Sgr A*) is the supermassive black hole at the center of our galaxy. Obviously you can't just take a picture of a black hole; you can only observe the effects it has on everything around it. The gases spinning around and falling into black holes are called the accretion disk; this image, taken in polarized light, show the structures and strength of the magnetic fields in the accretion disk. Our universe is so endlessly cool.
