Revision as of 07:24, 6 September 2009

The Milky Way Galaxy is a fairly ordinary spiral Galaxycontaining Spiral Arms, astronomers call it a barred spiral. It is 100,000 light years in diameter and 1,000 light years in thickness. with between 200-400 billion stars and that is a lot of stars. All that makes it a giant galaxy, bigger than most galaxies in its neighbourhood but the Milky Way is not as large as the Great Andromeda Galaxy, M 31. The Milky Way Galaxy is incredibly old and formed not more than about 1 billion years after the Big Bang and at its centre is an enormous black hole. We don't know if Extraterrestrial aliens are there.

Can you see the Milky Way Galaxy? Yes you can, just look around you. The Milky Way Galaxy is our galaxy, the Earth and the Solar System are part of it.
