The Pac-Man Nebula

The Pac-Man Nebula in Cassiopeia constellation
Moving away from out two Soul and Heart sisters towards Cassiopeia, we find this hungry little guy, NGC 281, better known as the Pac-Man Nebula.
Located in the Perseus arm of our own galaxy, it is a bright emission nebula, among an H II region, which means the hydrogen gas is ionized and, thanks to the strong radiation from the starts at its core, emits this beautiful glow for us to behold.
