The bright star clusters are beautiful scenes that fascinate, and delight sky watchers over and over again over the years. Above all, this is fascinating objects. In addition, star clusters shine like celestial diamonds. Many of these objects are visible to the naked eye. The Pleiades (seven sisters) are a well-known star cluster. A well-known cluster of stars seen from the southern hemisphere is the NGC 3532 Pincushion cluster. NGC 3532 was included in the astronomical catalogs in 1755. It was discovered by astronomer Nicolas Louis de Lacaille three years ago – 1752. In the constellation Carina, Lacaille defined the bright open group NGC 3532.

Pincushion star cluster

The distance of this cluster is estimated at 1300 light-years, and it covers an area of ​​the sky that is twice the size of the full moon. In addition to the Pleiades, NGC 3532 is one of the most fascinating open star clusters in the entire sky. If you look at the photo, you can see why the NGC 3532 is also called the Pincushion Cluster. The stars are like pins stuck in a pillow. This bright star cluster is also called the Football Cluster by many, in other words is because NGC 3532 is an oval starry sky. To many observers, this shape reminds them of a rugby ball. After that there is name – Football Cluster. NGC 3532 reminded me of spilled diamonds in the sky. For instance, I would also call this open star cluster the Diamond Cluster.

Age NGC 3532 star cluster

By standards, the age of the Pincushion NGC 3532 cluster is estimated at 300 million years. In other words, a young cluster. NGC 3532 qualifies as a medieval old star cluster. The NGC 3532 region consists of approximately 400 stars. Therefore, use a telescope. In the background we see the Milky Way area rich in stars. Traces of dust block the view of more distant stars. However, this should not fool you. Probably those stars (in the background) are not part of the open set. Observing the cluster of stars NGC 3532, it is noticeable that the most massive stars have ended their existence. They exploded like supernovae. The star cluster is rich in blue and orange stars of moderate mass. The more massive stars became red giant stars. In other words, the stars have depleted their hydrogen fuel supplies. Above all, a fascinating object.
