Sagittarius A*.

This is the first image of the monstrous black hole that inhabits the center of our galaxy.

It is known as Sagittarius A*, and has a mass four million times that of our Sun.

A central dark region, where the hole resides, is seen in the image, surrounded by light from super-hot gas that is accelerated by immense gravitational forces.

This ring is about 60 million kilometersabout the size of Mercury’s orbit around the Sun.
