Not all star clusters are what they seem… ✨ This glittering field of stars is NGC 1786, a globular cluster in the constellation Dorado, some 160 000 light-years away in the Large Magellanic Cloud — a small companion galaxy to our Milky Way. First spotted in 1835 by John Herschel, it’s a dense, ancient sphere of stars acting as a cosmic time capsule. For years, astronomers thought clusters like this formed all at once. But Hubble has revealed a twist: multiple generations of stars exist within them. By comparing globular clusters in nearby galaxies — the Large and Small Magellanic Clouds and the Fornax dwarf galaxy — with those in our own Milky Way, we’re uncovering how galaxies, including ours, took shape. Each pinpoint of light tells part of our shared cosmic history. 📹 @europeanspaceagency / @hubbleesa & @NASA, M. Monelli, N.
