Hubble Space Telescope spots one of the smallest galaxies ever discovered -- with a giant black hole at its core.

CNN Reports:

NASA said Wednesday that astronomers using its Hubble Space Telescope have found a new dwarf galaxy -- known as M60-UCD1 -- that "crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th" the diameter of the Milky Way galaxy.


At the core of this tiny galaxy is what NASA is calling a "supermassive," or "monster" black hole, one that has five times the mass of the black hole at the center of our own Milky Way galaxy. A dwarf galaxy is one that has a small fraction of the hundreds of billion of stars in the Milky Way.


However, when comparing the density of the Milky Way and the newly-discovered galaxy, NASA said looking at the nighttime sky from Earth reveals about 4,000 stars. Someone looking up into the sky from inside M60-UCD1 would see a million stars.


This is amazing. Think of looking up in the sky and seeing a million stars.  Awesome!
