The Pacman nebula (NGC281) is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes the open cluster IC 1590, the multiple star HD 5005, and several Bok globules. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.  IC59 and IC63 (on the left) are a combination of reflection and emission nebulae. The bluish glow shinning down from the top comes from the intense radiation of the bright star Gamma Cassiopeia. The edges of the nebulae glow brightly from this intense energy that is evaporating and lighting up these amazing clouds of gas and dust..  NGC 457 (bottom left) is an open star cluster in the constellation Cassiopeia. It was lies over 7,900 light years away from the Sun. It has an estimated age of 21 million years.
