First Image of a Black Hole Captured in M87
The historic first image of a black hole was released by the Event Horizon Telescope (EHT) Collaboration on April 10, 2019. An international team of scientists used observations with the Event Horizon Telescope, a worldwide network of eight ground-based radio telescopes, to capture an image of the supermassive black hole at the heart of the supergiant elliptical galaxy Messier 87 (Virgo A).

Virgo Cluster
The Virgo Cluster is the closest large cluster of galaxies to the Milky Way. With over a thousand known members, the cluster spans an area of the sky about 5 by 3 degrees in size. While some of the most prominent members can be seen in smaller instruments, a 6-inch telescope will reveal about 160 galaxies in this region on a clear night.

Markarian’s Chain
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.
