The constellation Virgo holds some of the finest collection of galaxies in the night sky with configurations that makes one marvel at the varying shapes of gravitationally interacting stellar material in the universe. It is not uncommon to find two galaxies interacting together. However, it is not too common to find four interacting galaxies close enough for the scrutiny of amateur telescopes. The interacting group of galaxies NGC 4410, NGC 4410b, IC790, VCC934, and VCC914, a possible fifth interacting galaxy, is one such example found in the upper center of this six-hour image. NGC4410 is a LINER-type galaxy with an active high energy nucleus believed to be a result of accretion of mass by a super-massive black hole at its center. The two larger spiral galaxies below are NGC4411 and NGC4411b.
