The Horsehead Nebula (also known as Barnard 33 or B33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion molecular cloud complex.
The Flame Nebula, designated...
The Orion Nebula (also known as Messier 42 or M42) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky ...
The Lagoon Nebula (catalogued as Messier 8 or M8) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula. The nebula contains a number of dark, collapsing clouds of protostellar material. It also includes a funnel-like or structure caused by ...
In 1786, William Herschel observing from Slough, England, noted a “faint milky nebulosity scattered over this space, in some places pretty bright.” The most prominent region was catalogued by his son John Herschel on 1829. It was listed in the New General Catalogue as NGC 7000, where it is descr...
The Cygnus Loop is a large supernova remnant in the constellation Cygnus, an emission nebula measuring nearly 3° across. Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range.
The visual portion of the Cygnus Loop is kn...

More work on this image has revealed some of the gaseous secrets of the Eagle Nebula and the Pillars of Creation.
The Pillars of Creation, captured in great detail by the Hubble Space Telescope, is an iconic feature of the Eagle Nebula. The faint blue colors in the bottom of th...
NGC 2359 (also known as Thor's Helmet) is an emission nebula[3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-su...
The Rosette Nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
The Heart Nebula (also known as the Running Dog Nebula and Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydr...
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a st...
The Iris Nebula (also known as NGC 7023) is a bright reflection nebula in the constellation Cepheus. The nebula lies 1,300 light-years away and is six light-years across.
The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope. It corresponds wit...

NGC 7380 is a young open cluster of stars in the northern constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′. German-born astronomer William Herschel included his siste...
