"Types Of Galaxies"

| Andromeda Galaxy |
All Galaxies do not look into alike.In fact,there are three main kinds of galaxies - spiral,elliptical,and irregular.The most beautiful types of galaxies are the spiral galaxies.Their long twisting arms are are-as where stars are being formed.Did you know that we belong to a spiral galaxy ?
The stars found in elliptical galaxies are often very old.This is because elliptical galaxies don't actively create new stars.The stars in the elliptical galaxy are often very close together making the center look like one gaint star.
Irregular galaxies are simply all the galaxies that are not spiral or elliptical.Many irregular galaxies probably used to be spiral,or elliptical until they had some kind of accident,such as crashing into another galaxy,which changed them.Many other irregular galaxies probably were never spiral or elliptical;they simply didn't evolve that way.
The Andromeda galaxy is one of the nearest large galaxies which is about 2.2 million light years away.The other two galaxies are small irregular galaxies called the Magellanic Clouds,and they are relatively near the Milky Way.The Large Magellanic Cloud is at about 160,000 light years,and the small Magellanic Cloud is at about 200,000 light years from us.In 2003,yet another galaxy has been discovered just 42,000 light years from the center of our galaxy.The CanisMajorDwarf,with about one billion stars,is probably our nearest neighbour!
