Cluster
My images of open and globular star clusters, from loose groups of young stars to dense, ancient spheres of very old stars.

NGC 1851: Globular Cluster in Columba
A dense globular cluster in the southern constellation Columba, about 39,500 light-years away, with a very compact core and an extended halo.

M5: Globular Cluster in Serpens
One of the oldest and largest globular clusters in the Milky Way, its blazing core surrounded by a vast swarm of red giants and blue stars.

M13: The Great Globular Cluster in Hercules
One of the most spectacular globular clusters in the northern sky, a dense sphere of several hundred thousand ancient stars resolved right down to its core.

M22: The Great Sagittarius Cluster
One of the nearest globular clusters to Earth, set against the dense star fields of the Milky Way toward the galactic center.

M45: The Pleiades
The famous Seven Sisters open cluster, its hot blue stars wrapped in delicate wisps of reflection nebula.
