Images of Galaxies
Today’s post will focus on images of galaxies. As we’ve discussed before, galaxies are collections of stars, dust, gas, pulsars, quasars, magnatars, and other cosmic bodies all bound together by their common gravity. The image above is the Andromeda Galaxy.
The Andromeda Galaxy is also known as Messier Object 31 or M31. It is a spiral galaxy located about 2.5 million light years away from Earth. It gets it’s name from the constellation Andromeda, which coincidentally enough, is where it is located.
Another favorite galaxy image of mine is the Sombrero Galaxy. This galaxy is also known as M104 and can be found in the constellation Virgo. The interesting thing about the Sombrero Galaxy is that it is an unbarred galaxy – meaning that it does not have the spiral arms found in spiral galaxies.
A ring galaxy is a bit of an oddity because it does not have much luminous material in the center of the galaxy as you see in other types of galaxies. Scientists speculate that ring galaxies may have been formed by two galaxies colliding leaving the ring galaxy without it’s central mass.
