Nearly 15 light-years in size and located in Cygnus, some 4,000 ly away from us, this beautiful object is another stellar nursery, IC 5146 or Sh 2-125, the Cocoon Nebula. The ‘cocoon’ we see is an open cluster embedded within
IC 1396 is one of the largest ionized gas nebula in the night sky (occupies full 3 degrees in the sky — which is six diameters of the Moon when seen from Earth). It is located in the constellation of
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
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
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,
Outters 4 (Ou4) is a very mysterious object, not only because it does not have its own wikipedia page in English. Colloquially called a Squid (or a Giant Squid) Nebula it was discovered only in 2011 by a French amateur
Melotte 15 is the central region of the Heart Nebula (IC 1805), some 7,500 light years away from us. Melotte 15 is a relatively small open cluster of stars some 1.5 million years old, some of them 50-times more massive
The Orion Nebula (M42 or NGC 1976), the colorful giant, got the distinctive honor to be designated the number 42 in the Messier catalog. M42, looking like a fuzzy star, can be seen by the naked eye in the middle
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
