The Antenna galaxies are located 63 million light-years away in the constellation of Corvus. What is seen here is the result of a collision between two galaxies several million years ago. The bright orange areas depict the cores of the two galaxies and the blueish parts are massive areas of star formation triggered by the merger of the two galaxies. The Antenna galaxies are obviously undergoing huge amounts of stellar birth which will continue for many millions of years.
