The Cartwheel Galaxy is a lenticular galaxy located around 500 million light-years away in the constellation of Sculptor.
Also known as ESO 350-40, IRAS 00352-3359 and LEDA 2248, it has a diameter of 150,000 light-years and a mass of about 3 billion solar masses.
The cartwheel shape of this galaxy is the result of a violent galactic collision.
“The Cartwheel Galaxy was once a normal spiral galaxy that underwent a head-on interaction with a smaller companion galaxy several million years ago, giving it its signature cartwheel appearance,” ESO astronomers said.
