GREENBELT, Md., Sept. 17 (UPI) -- NASA made a big announcement on Wednesday: the Hubble Space Telescope has found the smallest galaxy ever known.

But that wasn't the big news. It was what astronomers found inside of the galaxy that has them excited: a monster black hole right in the middle of the galaxy.

In a news release, NASA said the black hole is "five times the mass of the one at the center of our Milky Way galaxy."

The black hole was found inside the dwarf galaxy M60-UCD1. That galaxy is what's called a dwarf galaxy -- 140 million stars are crammed within a diameter of about 300 light-years.

NASA said if we lived inside of a dwarf galaxy you could see one million stars with the naked eye. We can see about 4,000 stars in our nighttime sky.
