Irregular Galaxies

Demonstrate an understanding of the appearance of irregular galaxies

Irregular galaxies do not fit into the tuning fork diagram and usually bear no relation to the shapes of other galaxies or have any obvious symmetry. Their strange shape may have arisen because of disturbances from other galaxies.

An example of an irregular galaxy is the Small Magellanic Cloud in Tucana.

Some textbooks call these lenticular or peculiar Galaxies.
