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.

This image, taken in August 2014 by the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT), shows the Cartwheel Galaxy before SN 2021afdx took place.

“Supernovae are one of the reasons we say we are all made of stardust: they sprinkle the surrounding space with heavy elements forged by the progenitor star, which may end up being part of later generations of stars, the planets around them and life that may exist in those planets.”

The Cartwheel Galaxy

The shape of the Cartwheel galaxy is the result of a galactic collision.
