Antennae Galaxies
The Antennae Galaxies are a pair of colliding galaxies located in Corvus constellation. The interacting spiral galaxies have the designations NGC 4038 and NGC 4039.
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.
