Messier galaxies M84 and M86 are part of Markarian’s Chain, a striking stretch of galaxies that lie along a curved line near the heart of the Virgo Cluster. The string of galaxies – which also includes NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435 – occupies more than a full degree on the border between Virgo and Coma Berenices and can be seen in an 8-inch reflector on a clear, dark night.
