Sagittarius

Sagittarius A* is the supermassive black hole at centre of our galaxy, the Milky Way.

That would be Sagittarius A*, the supermassive black hole at the center of the Milky Way whose mass is about 4 million times that of the sun.

While Sagittarius A* could be compared to a sleeping volcano, some SMBHs grow extremely rapidly by engulfing astronomic amounts of matter.

For those wondering, Swift — born Dec. 13, 1989 — and Dickinson share the same astrological sign: Sagittarius.

Many stars are observed near the supermassive black hole known as Sagittarius A* at the center of our Galaxy.
