Elliptical Galaxies

The stars found in Elliptical Galaxies are often very old. This is because elliptical galaxies don't actively create new stars.  The only stars found with in them were created along time ago.
Although they are usually smaller, this type of galaxy can be large. Most have only a few thousand stars, but some can have billions of stars. 
The stars in an elliptical galaxy are often very close together making the center look like one giant star.  If the Earth were inside an elliptical galaxy it would be bright both day and night.
