Shapes of galaxies

We cannot see our own Galaxy from the outside,so its difficult to know what exactly what shape it is.We do know that the Milky way is very similar to the andromeda galaxy,which is also a spiral galaxies.

Elliptical Galaxies
Many other galaxies are spherical or oval shaped,like a rugby ball.These are called Elliptical Galaxies.The stars that form the elliptical galaxies are not grouped in the form of a disc.They also tend to be red and old.

Spiral Galaxies
The spiral galaxies are very different from elliptical galaxies.Most of the stars in a spiral galaxy aae brighter and arranged in flat disc.that has lots of shining armss.The spiral arms may come directly from the center of the galaxy or from a sshort bar in the central part of the galaxy.In this case,The galaxies are called barred spirals.
