Astrophotograph of the irregular dwarf galaxy IC 10

This is my astrophotograph of the irregular dwarf galaxy in the constellation Cassiopeia with the catchy name, IC 10. Irregular galaxies do not have a distinctive regular shape like a spiral or an elliptical galaxy and often appear chaotic. This galaxy is also classified as a starburst galaxy because a normally rare type of star, Wolf-Rayet stars, which are massive and bright, are forming really quickly. It’s a bit of a strange object really and it wasn’t until the 1930s that it was recognised as a galaxy at a distance of >2 million light years, as opposed to a star cluster with nebulosity inside our own galaxy (which would have put it at a distance of <200 thousand light years).
