What are large clusters of stars called?

A star cluster is a group of stars that share a common origin and are gravitationally bound for some length of time. The two basic categories of stellar clusters are open clusters, also known as galactic clusters, and globular clusters.

Why do clusters of stars form?

The simplest idea is stars form into clusters when a giant cloud of gas and dust condenses. The center of the cloud pulls in material from its surroundings until it becomes dense enough to trigger star formation. From this study, they discovered the stars on the outskirts of the clusters actually are the oldest.

What type of stars are the largest?

Supergiant Stars: The largest stars in the Universe are supergiant stars. These are monsters with dozens of times the mass of the Sun. Unlike a relatively stable star like the Sun, supergiants are consuming hydrogen fuel at an enormous rate and will consume all the fuel in their cores within just a few million years.
