Astronomers report that the supermassive black hole at the center of the galaxy (known as Sgr A*) is becoming more active. The black hole’s output varies a little across the electromagnetic spectrum on a daily basis, but over the last few years, Sgr A*’s X-ray flares have become more energetic.

A dwarf starburst galaxy about 30 million light years from Earth.Henize 2-10 is a dwarf galaxy, and it is the first dwarf galaxy ever discovered to contain a supermassive black hole at its center. This was surprising because the black hole is about one quarter of the size of the one at the center of the Milky Way Galaxy. However, Henize 2-10 is only about1/1,000th the size of the Milky Way..
