Exploring the Faint Smudges of the Double Cluster in the Constellation of Perseus


Key Highlights :

1. The constellation of Perseus is seen from London at about 21.00 BST this week.
2. The Double Cluster can be seen with the naked eye under good conditions.
3. The clusters are about 7,500 light years away, meaning the light you see from them set out on its journey about 5500BC.




     The night sky is filled with fascinating sights, and one of the most breathtaking is the Double Cluster in the constellation of Perseus. This pair of adjacent star clusters can be seen with the naked eye under good conditions, although their faint smudges are easily overlooked. NGC 869 and NGC 884 are both about 7,500 light years away, meaning the light from them set out on its journey about 5500BC. The clusters represent the combined light from thousands of distant stars, making them a beautiful sight to behold.

     The Double Cluster is best viewed from the northern hemisphere, from locations such as London, UK. To get the best view, it is necessary to find a dark sky, away from street lamps, and allow your eyes to adjust to the dark. The Starwatch chart shows the constellation of Perseus as seen from London at about 21.00 BST this week.

     The Double Cluster is part of a larger constellation, that of Perseus, who famously rescued Andromeda from the sea monster Cetus in Greek mythology. It is easy to see why the constellation was named after the heroic figure, as it contains several deep-sky objects that make for a spectacular sight.

     Looking at the Double Cluster, it is hard to imagine that the light we are seeing is thousands of years old, having travelled through the vastness of space to reach us. It is a reminder of how small we are in the grand scheme of things, and how much there is to explore in the night sky.

     The Double Cluster is a wonderful sight to behold, and a reminder of the fascinating things that can be seen in the night sky. It is a beautiful sight, and one that is well worth seeking out.
