Subject:Named for astrophysicist, Benjamin Markarian, who discovered the galaxy groups' common motion in the early 1960s, Markarian's Chain includes the pair of interacting galaxies NGC 4438 and NGC 4435, about
50 million light-years away, known to some as
Markarian's Eyes. Some activity is destructive.
NGC4402 galaxy exhibits the destruction of material it once contained to enable formulation of stars which has been stripped away in a process known as "
ram-pressure stripping". This is due to NGC 4402's cooler gasses being struck by hot x-ray gasses coming from the middle of the Virgo galaxy cluster as it moves toward it. IC3355 galaxy is most interesting as it has a brightness of only 23.49 mag/arcsec2 These galaxies are all labeled in the image.
