📸 Messier 6 – The Butterfly Cluster

A cluster of about 100 young stars spreads its wings in Scorpius. Known as the Butterfly Cluster, Messier 6 glows with brilliant blue stars and one striking orange giant: BM Scorpii.
It spans 25 light-years near the heart of the Milky Way.

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.
