IC 2948 is a young open star cluster in the southern constellation Centaurus. It was discovered by astronomer A. David Thackeray in 1950 through his observation of the cluster’s Bok globules, now known as Thackeray’s Globules. IC 2948 is associated with the emission nebula IC 2944, also known as the Running Chicken Nebula or the […]

It is one of the largest star clusters in the Milky Way galaxy containing over a million stars across three separate generations of stars which were all born within 200 million years of the formation of the cluster. For NGC 2808 to contain […]

It was first discovered in 1834 by British astronomer John Herschel, and is considered an I2p cluster in the Trumpler open cluster classification system. This means the stars are strongly concentrated, they have an average range in […]
Read more "NGC 2910"Introduction NGC4609, alternatively recognized as Caldwell 98, is a young open cluster within the southern constellation of Crux – a cross-shaped asterism often referred to as the Southern Cross. A fascinating fact about the Crux constellation is that it is widely used as a national and distinctive symbol in many countries (Wikipedia contributors, 2024). Figure […]

It was catalogued by Per Collinder in 1931 and has unusually low extinction leading some to argue that the cluster doesn’t exist at all Kaltcheva 2001. In order to study NGC 2439 I collected 15 images using the Prompt6 telescope, […]

It was first discovered by Scottish astronomer James Dunlop in 1826 and is estimated to be over 1.2 billion years old. Interestingly, the NGC 3680 star cluster was classified as containing less than 50 stars, yet the number of stars making […]
