The NASA/ESA Hubble Space Telescope has provided a delightful view of the crowded stellar encampment called Messier 68, a spherical, star-filled region of space known as a globular cluster.
About 160 globular clusters have been spotted encircling our galaxy, the Milky Way, mostly toward its bulging centre.
Gamma ray burst, which occurred in a colossal group of stars called a globular cluster may have triggered a mass extinction on Earth 440 million years ago.
