The Antennae Galaxies, also known as the Ringtail Galaxy or Arp 244, are a pair of colliding galaxies located in Corvus constellation. The interacting spiral galaxies have the designations NGC 4038 and NGC 4039 in the New General Catalogue.
The galaxy collision resembles an insect’s antennae, which is how the pair got the name. The “antennae” are formed by two long tails of stars, dust and gas expelled from the galaxies as a result of their interaction.
