Elliptical Galaxy is a galaxy that looks like a round or flattened ball and contains little gas and dust between the stars.

Explanation:

Elliptical galaxies are galaxies in the universe which look like flattened balls. They contain billions of stars but between these stars, there is only very little gas and dust. So new stars are no longer forming in these galaxies. As new stars are not forming, most of the elliptical galaxies in space contain very old stars. Elliptical galaxies are named by using the alphabet E and numbers between 0 to 7. Examples are E0 and E7.
