It was first discovered by Caroline Herschel, however was never officially brought to attention until her brother William included NGC 2360 in his 1783 catalog of 1000 star clusters and nebulae. In a recent study, […]
Read more "NGC 2360"The intermediate star cluster NGC 3330 is actually quite intriguing in the lack of references around it. Specifically the lack of references on SIMBAD and Wikipedia. There actually were plenty of Wikipedia articles regarding this star cluster, just not in English. So the French article states that it was first discovered on April 29 1826 […]

It was said to be discovered by DeLisle Stewart in Jun 13, 1901, and was thought to be unusual due to the determined metallicity in 1995, made it appear […]
Read more "IC 4499"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 […]
