For example, the Andromeda Galaxy is known as both M31 and NGC224. The Largest Galaxy At the moment, the largest Galaxy we know of is the IC 1101, an elliptical galaxy that is at the heart of a group of galaxies known as the Abell 2029 Galaxy Cluster. Sir William Herschel discovered ...
What Is a Cluster? Many people only a computer to check email and social media and to perform basic office tasks. If this is your workload, you don’t need much processing power. A thin and light laptop can quickly handle your processing needs. These devices can have processors that requi...

What is a star cluster?Question:What is a star cluster?Stellar Connections:Every galaxy in the universe includes hundreds of billions of stars. The stars often interconnect, and constellations are an example of this. These constellations appear to form images in the night sky.Answer...
What is the difference between a globular cluster and an open cluster? Through a telescope, a globular cluster appears as a round ball of light. Its center is tightly packed and made of an indistinguishable myriad of stars.Open clustersare much more irregular in shape, less densely packed, an...
What is a cluster diagram? In a broader sense, a cluster diagram is exactly what you would expect from the name. This type of diagram represents some sort of cluster, ideas or objects that are positioned closely together. For the purpose of this article, we’ll refer to the cluster diagra...
Abell's definition of a cluster is this: First, there have to be more than 50 galaxies within a specific amount of space. He said basically that clusters have a radius of roughly 2 megaparsecs. And it was just an assumption that all clusters would be about the same size. ...
(Milone et al.2015b; Carretta et al.2015). NGC 2419, a very massive cluster with a very large apocenter distance, also shares many characteristics of the chromosome map with NGC 2808, as suggested by the very recent study by Zennaro et al. (2019). However, it is not plotted in ...
An open star cluster is a young bundle of stars, irregularly shaped and found in the galactic plane. There are many open clusters in the Milky Way.
the recently discovered ultra-faint dwarf spheroidal (dSph) galaxies which contain very few stars, has motivated us to as the question 'What is a galaxy?' Our aim here is to promote further discussion of how to define a galaxy and, in particular, what separates it from a star ...
