A GALAXY Does consist of stars.It's consisted out of gas,dust,and stars.
Yes. The Andromeda Galaxy contains about a trillion stars, many of which probably have planets. There are also many clouds of gas and dust.
A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
A group of stars, dust and gases held together by gravity IS CALLED GALAXY
Almost all of the galaxies have dust in them, most have new stars, but I think you are thinking of the Horse head nebula which is cited as a stella nursery.
A small galaxy with stars and very little dust is commonly called an elliptical galaxy. Elliptical galaxies are extremely small and typically made up of smaller and older stars.
