About 105.8 Mpc distant, have experienced a collision, and will continue colliding until they coalesce.
The colors of the galaxies are peculiar. In NGC 4676A a core with some dark markings is surrounded by a bluish white remnant of spiral arms. The tail is unusual, starting out blue and terminating in a more yellowish color, despite the fact that the beginning of each arm in virtually every spiral galaxy starts yellow and terminates in a bluish color. NGC 4676B has a yellowish core and two arcs; arm remnants underneath are bluish as well.
The galaxies were photographed in 2002 by the Hubble Space Telescope. In the background of the Mice Galaxies, there are over 3000 galaxies, at distances up to 13 billion light-years.
