Hubble Spies Starry Chandelier
The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be others still undiscovered, hidden from view by dust…

Hubble Captures Star-Studded Cluster
This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are sprinkled around the outer regions of…

Starry Chandelier Cluster
This image released on June 26, 2026, features the globular cluster NGC 6723, sometimes called the Chandelier Cluster. Like its namesake, it sparkles with countless lights. However, each ‘lightbulb’ in this chandelier is an individual star 27,000 light-years away in the constellation Sagittarius (the Archer). Globular clusters like NGC 6723 contain some of the oldest stars in our galaxy. These…

Hubble Observations Give “Missing” Globular Cluster Time to Shine
A previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular clusters like this one, called ESO 591-12 or Palomar 8, are spherical collections of tens of thousands to millions of stars tightly bound together by gravity. Globular clusters generally form early in the galaxies’ histories in regions rich in gas and dust. Since the stars…
