Swan Nebula (M17) Imaged by Chris Thayer

M17, the Swan Nebula (also designated NGC 6618) is an emission nebula (HII region) in the constellation of Sagittarius.  The radiation of a cluster of stars embedded in nebula is exciting the gass and causing the emission.  It is roughly 40 light years in diameter and is  over 5,000 ly away.  ...

Crescent Nebula Imaged by Chris Thayer

The Crescent Nebula (also designated NGC 6888 and Caldwell 27 on Patrick Moore’s Caldwell catalogue) is an emission nebula in the constellation of Cygnus. It was formed by fast stellar winds from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind (ejected by...

Veil Nebula Imaged by Peter Campbell-Burns

The Veil Nebula, also known as the Cygnus Loop or the Witch’s Broom Nebula, is a large, relatively faint supernova remnant in the constellation Cygnus. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area of ~3×3 degrees; about...
