What different shapes can galaxies have?
Jul 16, 2017
There are mainly four types...
- SPIRAL galaxies consist of a rotating disk with arms. Its center is plenty of old stars. This shape is considered the most common shape in the universe.

- ELLIPTICAL galaxies have no dust lane and have fewer stellar material, more open clusters. The star formation rate is relatively
low. More random orbits.
- LENTICULAR galaxies often have a central bulge surrounded by a disk-like structure with dust lanes. Star-forming regions are not present. They are sometimes referred as transition states between elliptical and spiral galaxies.
- IRREGULAR galaxies relate to their indeterminate shape. Their inability to assume a regular form is due to their scarce gravitational force, meaning that they cannot get bigger.
