-A galaxy is a group of millions or even billions of stars. Some of these stars become black holes when they get old and collapse. Some galaxies are spiral ,some are elliptical and some are irregular. Our solar system is in the Milky Way galaxy. The Milky Way is a spiral galaxy.

Spiral Galaxy	Elliptical Galaxy	Irregular Galaxy

Welcome to the MILKY WAY GALAXY. Astronomers have produced the best image yet of what our  home galaxy would look like to an intergalactic traveller far above the MILKY WAY .The new image , created by scientists using the Spitzer space telescope ,an infrared sister of the Hubble shows that the Milky Way's spiral arms are linked at the centre by a straight bar,27,000 light years long-7000 light years longer than previously thought.  This is the Milky Way from the side.
