The Pleiades or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Ta**us. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster, but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.

The NGC 6992 Nebula is a fascinating and complex part of the Veil Nebula, representing the remnant of an exploded supernova. Its filamentary structures and distinctive features offer a unique opportunity to study stellar evolution and the physical processes that occur in the final stages of a massive star

The Pelican Nebula (also known as IC 5070) is an H II region associated with the North America Nebula in the constellation of Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a foreground molecular cloud filled with dark dust.

The Horsehead Nebula is a small dark nebula located just to the south of the bright star Alnitak - the left-most star on Orions Belt. It is located some 1300 light-year from the earth. On the other side of Alnitak is the Flame Nebula. This object was discovered by the Scottish Astronomer Willamina Flaming on a photographic plate taken by the Harvard College Observatory in 1888. It was first cataloged by E.E Barnard a dark nebula designated as Barnard 33.

The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.

The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is cataloged as IC 4703. This currently active star-forming region is about 5,700 light-years away. A spiral of gas that can be seen emerging from the nebula in the northeastern part is about 9.5 light-years or about 90 trillion kilometers long.

The cluster associated with the nebula has about 8,100 stars, which are mostly concentrated in an empty space in the molecular cloud northwest of the Pillars. The brightest star (HD 168076) has an apparent magnitude of +8.24, easily visible in good binoculars. It is actually a binary star consisting of an O3.5V star plus an O7.5V companion. This star has a mass of about 80 solar masses and a luminosity of up to 1 million times that of the Sun. The age of the cluster has been estimated at 1-2 million years.

Two of the most beautiful summer nebulae: the Lagoon Nebula (M8) and the Trifid Nebula (also called M20). The first is an emission nebula, the second, in addition to having an emission zone, has a reflection and a dark component (hence the name Trifid).
These differences cause the two objects to appear different in color: the reddish comes from ionized hydrogen atoms (infrared emission at 656nm), the bluish comes from the reflected light of adjacent stars.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion’s Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 light years and is the closest region of massive star formation to Earth.

IC 1795 - The Fish Head Nebula, also known as the Northern Bear Nebula, is part of a huge star forming system of gas and dust located along the Perseus spiral arm of our Milky Way galaxy.  The nebula is located in the constellation Cassiopeia approximately 6000 light-years from the Earth and is adjacent to the much larger Heart Nebula.  The brighter region of IC 1795 is designated NGC 896 and is the home to many massive, young, stars.  These stars radiate copious amounts of ultraviolet light.  This UV radiation excites the surrounding gas and causes it shine much the same way as a neon light emits its colorful hues.

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. (In the Spitzer Space Telescope view shown, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
