NGC 2571 is an open young Cluster in the Puppis Constellation, and it is situated of the south celestial equator means it is more easily visible from the southern Hemisphere. NGC 2571 was identified during the era of systematic sky surveys in the 19th century, and it was Compiled by John Dreyer in 1880âs). open […]
Read more "NGC 2571"NGC 2194 is an intermediate open cluster in the Orion constellation, estimated to be 330 million years of age. It was discovered by William Herschel on February 11, 1784. It’s close proximity to the celestial equator allows the cluster to be visible from both hemispheres in certain times of the year. In order to study […]
Read more "NGC 2194"NGC 2439 is a sparse, young, open cluster in the southern constellation Puppis. A study by Eggenberger, Meynet, and Maeder (2002) found that its ratio of blue to red supergiants was in line with other clusters of similar age and position in the galaxy. To properly analyze this cluster myself I made observations using the […]

There exist two main types of star clusters – globular clusters are tight groups of ten thousand to millions of old gravitationally bound stars, and open clusters are groups of tens to a few thousand stars formed from the same molecular […]

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 […]

Amongst the Caldwell designation, there have been many other categorizations of this star from Collinder, Melotte, Lacaille III, and Dunlop. (Wiki, 2024) NGc 6025 is a intermediate open […]

It can be seen with the naked eye under dark skies as a 6th magnitude star, making it an accessible object for amateur astronomers without the need for telescopes. The cluster’s brightest stars […]

It was discovered in 1751 by Abbe Lacaille during his expedition to the Cape of Good Hope. In a study done by M.J.Rain et al., (2021), a new Gaia-based catalogue of blue stragglers in open clusters was […]
Read more "NGC 6025"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 […]
Read more "NGC 4609 | An Open Cluster in Crux"NGC 2439 is a young, open cluster of 824 stars in the Southern constellation Puppis. 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, […]
