Hercules Cluster — star cluster, shown live in Cosmoscope, a real-time 3D map of the universe.
A third of a million ancient stars packed into a ball — some nearly as old as the universe itself, orbiting the galaxy far above its disc.
Hercules Cluster is placed at its true position on the sky and at its real measured distance, not as a flat backdrop. Fly out from the Sun in the live 3D view and watch it change from a point of light into structure as you approach, with the scale bar showing just how far out you have travelled.
