Messier 81 (also known as NGC 3031 or Bode’s Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Its active galactic nucleus harbors a supermassive black hole with roughly 70,000,000 X the mass of the Sun.

The Hubble Space Telescope has resolved some strange objects nicknamed “blue blobs” and found them to be brilliant blue clusters of stars born in the swirls and eddies of a galactic smashup 200 million years ago. These “blue blobs” exist along a wispy bridge of gas strung among three colliding galaxies, M81, M82, and NGC 3077about 12 million light-years away from Earth. This is not a place astronomers expect to find star clusters because the gas filaments should be too thin to allow enough material to accumulate and actually build so many stars. The star clusters in this diffuse structure might have formed from gas collisions and subsequent turbulence which locally enhanced the density of the gas streams.
