Colliding galaxies NGC4038-39 - 'The Antennae'

The two colliding galaxies NGC4038 & NGC4039 are known as the 'Antennae' because of the long insect-like tidal streamers of stars extending out in opposite directions from the cores.
The bright blue knots in the galaxies disturbed cores are enormous star forming regions, triggered by the compression of interstellar gas due to the collision.
The Antennae galaxies are located about 63 million light years away in the southern constellation Corvus.
