Cartwheel Galaxy

  • by

The Cartwheel Galaxy is a lenticular galaxy and ring galaxy located in the southern constellation Sculptor. The galaxy lies at an approximate distance of 496 million light years from Earth. It is about 150,000 light years across in size, which makes it slightly larger than the Milky Way.

The galaxy’s unusual appearance resembles that of a wagon wheel and has earned it the nickname Cartwheel. The galaxy has been tidally distorted by a collision with another galaxy into the ring-and-hub or cartwheel structure for which it is known.

Southern Pinwheel Galaxy – Messier 83

  • by

The Southern Pinwheel Galaxy, also known as Messier 83 (M83), is a barred spiral galaxy located in Hydra constellation. M83 lies at a distance of 15 million light years from Earth. It is one of the nearest and brightest spiral galaxies, and can even be seen in binoculars. The galaxy appears face-on when viewed from Earth.

Messier 83 was nicknamed the Southern Pinwheel Galaxy because of its prominent, very well defined spiral arms, which give the galaxy an appearance similar to the famous Pinwheel Galaxy (Messier 101), located in Ursa Major. Messier 83 has the designation NGC 5236 in the New General Catalogue.
