M7 Open Star Cluster in Scorpius: 14 Sept 2012
An open star cluster is a group of stars held together by gravity. The star cluster pictured above, located in Scorpius, is one of the most visible in the night sky. The myth surrounding the constellation Scorpius is that he was sent to kill Orion by the Earth goddess Gaia after Orion attempted to kill all of the animals on Earth. This star cluster is located in the tail of the scorpion and is commonly referred to as M7. The star cluster is about 1000 light years away and contains around 100 stars. Ptolemy observed this star cluster in 130 AD, before it was numbered by Messier.
