Hubble Space Telescope image of the globular cluster M80 (NGC 6093), showcasing a dense concentration of stars. Many are older and redder than our sun, but the presence of numerous blue stragglers—younger stars formed from stellar collisions—indicates a high collision rate at the cluster's core.

A stunning image of NGC 6752, a globular star cluster located 13,000 light-years away in the constellation Pavo. This ancient cluster, over 10 billion years old, contains over 100,000 stars and showcases a variety of stellar types, including blue stragglers and red giants. The image reveals the cluster's dense core and the distribution of stars against the backdrop of the Milky Way's halo. A bright foreground star is also visible.

Hubble Space Telescope image of the central region of NGC 6397, a globular star cluster. The brighter blue stars near the center are likely the result of stellar collisions, forming "blue stragglers" more massive than other stars in the cluster. This provides evidence of star collisions in dense stellar environments.
