About this image

ARP 242 - The Mice Galaxies - is a pair of interacting galaxies in the constellation of Coma Berenices about 300 million light-years from Earth. They were discovered by William Herschel on March 13, 1785 giving them designation NGC 4676. The northern galaxy is IC 819 and the southern IC 820. I'm intrigued at how the night sky must appear when viewed from within one of these galaxies, with two "milky ways" crossing the sky.
