description Overview

NGC 281

NGC 281 is an emission nebula and active star-forming region in the constellation Cassiopeia, commonly called the Pacman Nebula because of its appearance in some images. It is associated with the young open cluster IC 1590, whose hot stars ionize surrounding hydrogen gas and make it glow. The region also contains dark dust lanes and dense globules where continuing stellar formation can be studied.

Bubble Nebula

The Bubble Nebula, formally NGC 7635, is an emission nebula located within the Cassiopeia constellation. It's notable for its distinctive bubble-like structure created by the energetic output of the star BD+60 2522. Discovered by William Herschel in 1787, it’s a region of ionized hydrogen gas (HII) studied by astronomers and those interested in stellar evolution and planetary nebula formation.
