This image of the beautiful open star cluster around the bright star Mirfak in Perseus was taken by Martin Gembec of the Czech Republic in 2007. Mirfak dominates the centre, with the stars of the cluster, also known as Melotte 20, the Alpha Persei Moving Group, and the Little Cloud of Pirates, sprinkled mainly to…

The globular star cluster known as Messier 22 and the Great Sagittarius Cluster. Venus will shine near this object this week. The cluster spans about one-third of the full moon’s diameter and is visible in binoculars and backyard telescopes. The best time to view its rich, “sugar on black velvet” spectacle is during the summer…
