Originally a catalog of things that were not comets, Charles Messier compiled a list of some of the best night sky objects.
The New General Catalog is the largest and most widely used catalog of deep sky objects. It contains over 7,800 galaxies, nebulae, and star clusters.
Assembled by Sir Patrick Caldwell-Moore, this 109 object catalog was designed to be both a compliment and an extension to Messie's list.
Formed over billions of years, Galaxies are vast complexes of stars, gas and dust bound together by gravity.
Often the birthplace of stars, nebulae are vast complexes of gas and dust where stars are born, evolve, and die.
From grand globular clusters to ornate open clusters and everything else, check out the wide array of star formations in the galaxy.
Explore objects by the season! From bright nebulaue to stunning galaxies, see what's in the sky this time of the year.
The night sky is full of countless stories of heroes and demons, of myth and legend. Explore the night sky by its constellations.
