How do globular clusters form
Web1 day ago · Sep. 29, 2024 — Using the James Webb Space Telescope (JWST), researchers have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics ... WebThe three basic types of clusters astronomers have discovered are globular cluster s, open cluster s, and stellar association s. Their properties are summarized in Table 22.3. As we will see in the next section of this chapter, globular clusters contain only very old stars, whereas open clusters and associations contain young stars.
