The Antennae Galaxies, also known as NGC 4038 and NGC 4039, are completely intertwined. For the last hundred years the two galaxies have been clashing, sending out far flung stars and streamers of gas into space likes antennaes. The clouds of gas are bright pink and red, surrounded by blue star-forming regions.
