NGC 2345

The universe, a vast expanse of space that is home to countless galaxies, stars, and celestial bodies, has always been a subject of fascination and curiosity. Among these celestial wonders is NGC 2345, a young open cluster located in the Southern hemisphere constellation of Canis Major. Stellar clusters stand as celestial laboratories, offering researchers a […]

NGC 2539

NGC 2539 is an intermediate age open cluster located in the northern part of the Puppis constellation that was discovered by William Herschel on January 31, 1785. Out of all the hundreds of stars in the cluster there is estimated to be at least one triple system (Mermiliod and Mayor, 1989). I collected a total […]

NGC 2335

NGC 2335 is an Open Cluster in the Monoceros constellation. Discovered on Jan 10, 1785, by William Herschel, it is situated close to the celestial equator, and, as such, is at least partly visible from both hemispheres at certain times of the year. NGC 2335 is also the gateway to the Seagull Nebula and is […]

NGC 3766

Introduction NGC 3766, also known as Caldwell 97, is a striking star that may be seen in the Centaurus constellation in the southern sky. It was initially cataloged as NGC 3766 in 1751 while on a trip to the Cape of Good Hope. This cluster has captured the interest of astronomers all over the world. […]

NGC 5925

NGC 5925 is an intermediate age cluster estimated to be around 316 million years old, it’s located in the Southern constellation Norma. It is an open cluster that is 5070 light years away from Earth. A recent study made in 2021 found that in NGC 5925, the average number of blue straggler stars (BSS) increases with […]

ASTR113 Star Cluster NGC 3330

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 […]

NGC 2244

Located in the Rosette Nebula which lies in the constellation Monoceros we can find one of the very youngest magnetic upper main sequence stars, NGC 2244. NGC 2244 also known as Caldwell 50 or the Satellite Cluster is an open cluster star estimated to be less than 5 million years which was discovered by John […]

NGC 2194

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 […]

NGC2129

NGC2129 is an open cluster in the constellation Gemini. It is located approximately ~7,200 light years from the Sun inside the Local spiral arm. The discoverer of this open cluster is unclear as some sites say it was William Herschel who discovered it in February 6, 1782 while other’s have nothing listed. NGC2129 is a […]

ASTR 113 Star Clusters: NGC 2439

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 […]
