A rich star field showing Messier 6, the Butterfly Cluster. At the center, dozens of brilliant blue stars form a loose, wing-like shape against a background of reddish hydrogen gas. Near the top right of the cluster, a cooler orange star stands out—this is BM Scorpii. The stars sparkle sharply, and the reddish nebula glows around the edges of the frame, adding color and contrast.
A butterfly, made of stars. 🦋
Messier 6 is an open cluster in Scorpius, glowing with 100 young stars and one bright orange giant—BM Scorpii.
This cosmic butterfly stretches 25 light-years across the Milky Way.
