Globular clusters offer stunning starscapes for amateur astronomers, but the Hubble Space Telescope takes it to another level as seen in this jaw-dropping image of Messier 2 some 55,000 light years from Earth.
Globular clusters are favourite targets for amateur astronomers, vast star swarms that date back to just after the big bang birth of the cosmos. NGC 6397 is one of the closest, as revealed by the Hubble Space Telescope.
A middle-age star cluster in the Small Magellanic Cloud is populated by countless stars, but galaxies in the far distance peak through, giving viewers at least a sense of the overwhelming scale of the cosmos.
An unusual globular cluster on the outskirts of the Large Magellanic Cloud, seen here in an image captured by the Hubble Space Telescope, features an unusual mix of young an old stars, possibly the result of an encounter with a giant gas cloud in the distant past.
Messier 22 is a stunning sight in even small telescopes, but nothing rivals this spectacular view of the globular cluster’s crowded heart as imaged by the Hubble Space Telescope in visible and infrared light.
The great globular cluster in Hercules, M13, was first noted by western astronomers in 1714 when Edmund Halley described it as a “little patch” that “shews it self to the naked Eye.” The Hubble Space Telescope takes it to another level.
Globular clusters orbiting the core of the Milky Way are favourite targets for amateur astronomers, especially those in the Messier catalogue. It turns out one of them is the first extra-galactic globular ever discovered, something Charles Messier could not have imagined.
The Hubble Space Telescope captures a striking view of the globular cluster M79, a vast assembly of some 150,000 stars in the constellation Lepus that includes, like all clusters of its type, some of the oldest suns in the Milky Way.
