Small Galaxy Packs Black Hole Whopper


Recommended Posts


Astronomers have found a super-super-massive black hole comprising a whopping and unprecedented 59 percent of the mass of stars in the central bulge of its host galaxy, a discovery that adds a new twist to the mysterious relationship between a galaxy and its black hole.

The black hole inside the small, compact galaxy known as NGC 1277, located about 250 million light years away in the constellation Perseus, weighs in at 17 billion times the mass of the sun.

In comparison, the supermassive black hole at the heart of our Milky Way galaxy is equal to the mass of about 4 million suns.
