Butterfly Galaxies

March 31, 2003
Atlas Image mosaic, covering 5´ × 5´ on the sky of the galaxy pair NGC 4567 and NGC 4568, aka VV 219 and the "Butterfly Galaxies," in the Virgo Cluster of galaxies. The two spiral galaxies have small separation between them, but the question is whether or not they are gravitationally interacting. 2002 May 8-14
