A string of a dozen or so galaxies in the central region of the → Vigo cluster. The chain lies to the right of the cluster's dominant galaxy M87 and extends over nearly 2° on the sky. The chain's brightest galaxies are the lenticulars M84 and M86. At least seven galaxies in the chain appear to move coherently, although others appear to be superposed by chance.

Two → interacting galaxies, NGC 4438 and NGC 4435, located in → Markarian's chain of galaxies in the → Virgo cluster of galaxies. About 50 million → light-years away, the two galaxies are about 100,000 light-years apart. Gravitational → tidal forces from the → close encounter have ripped away at their stars, gas, and dust. The more massive NGC 4438 kept much of the material ripped out in the collision, while material from the smaller NGC 4435 was more easily lost.
