What Are Star Clusters?

Star clusters are amazing groups of stars that help us learn about the universe. They are like cosmic neighborhoods where stars live together. These groups show us how the universe was made³.

We find two main types of star clusters: open and globular. Each type is special and catches the eye of both scientists and sky watchers. People who love the stars can learn a lot by studying these groups studying celestial formations.

Defining Characteristics

Open clusters are lively places with a few hundred stars. They are young, usually less than tens of millions of years old³. These clusters can be up to 30 light-years wide³.

Globular Cluster Insights

Globular clusters are very different. They have thousands to millions of stars. These clusters are dense and round. They are also very old³.

Astronomical Significance

Star clusters are key for understanding the universe. They help scientists learn about star birth and life. By studying these groups, we can uncover the universe’s secrets³.

The Formation of Star Clusters

Star clusters are amazing cosmic structures that form through gravity and molecular clouds. The stellar evolution process starts in vast interstellar regions. Here, gas and dust are key in galaxy formation⁴.

Stellar Nurseries: Cosmic Cradles of Creation

Molecular clouds are incredible nurseries for star clusters. These environments create diverse stellar populations⁵:

Star clusters can have from a dozen to millions of stars⁴
Globular clusters have tens of thousands to millions of stars⁴
