The Heart Nebula (IC 1805, Sharpless 2-190, aka Running Dog Nebula), shown on the photograph in the lower right, and the Soul Nebula (Westerhout 5, IC 1848, Sharpless 2-199, aka Embryo Nebula) are located in the Perseus Arm of the
Bubble Nebula (NGC 7635)
The Bubble Nebula (NGC 7635, Sharpless 162, or Caldwell 11) is a bubble of interstellar atomic hydrogen (HII region) ionized by the strong ultraviolet radiation on the O-type hot star (BD+60°2522) that is within the nebula, but not in the
Pelican Nebula (IC 5070)
The Pelican Nebula (IC 5070), is another one of Milky Way’s stellar nurseries. It earned the name due to its shape when viewed in the visible spectrum, such as on this photo: the shape is defined by border of cold,

Rosette Nebula (NGC 2237)
The Rosette Nebula is a symmetrically-shaped region of ionized hydrogen (HII region) located at an edge of a huge molecular cloud in the constellation of Monoceros. More formally it is denoted as Caldwell 49, and also NGC 2237 (which also
Pacman Nebula (NGC 281)
NGC 281 is a bright emission nebula that resembles Ms. Pac-Man, more so when viewed in the visible spectrum (this photo is in narrowband). It’s more formal designations in various catalogs are NGC 281, IC 11 or Sh2-184. Objects lying on the Milky Way
