Star Cluster NGC 6603 in the M24 Small Sagittarius Star Cloud

There’s nothing particularly impressive or image worthy happening on the Sun at the moment so instead of concentrating on our own star I thought I would show you a few thousand ! The bright knot of stars at the centre of the image below is the open star cluster NGC 6603 buried deep in the heart of the brightest part of the M24 Small Sagittarius Star Cloud, close to the centre of our galaxy.

NGC 6603 was discovered by John Herschel around 1825-33 and includes 30 stars with an approximate age of 200 million years. The component stars shine at magnitude 11 or 12 and the larger stars dotted around its location in the foreground are magnitude 6.5 – 7.5. The surrounding star cloud as a whole is aged between 200 and 600 million years old. Lets take a closer look at the NGC 6603 cluster………
