IC 10 galaxy (19 September 2019)
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).
