Rosette Nebula
The Rosette Nebula, also known as Caldwell 49, is an emission nebula 5,200 ly from Earth in the constellation Monoceros.  The nebula is about 130 ly in diameter.  The open star cluster in the middle, NGC 2244, was formed from the nebula's matter and is less than 5 million years old.  This cluster has several O-type, super hot, stars that generate a large amount of radiation that excites the nebula gas.  Click on the image to see a larger version.

Soul Nebula
The Soul Nebula is an emission nebula 7,500 ly from Earth in the constellation Cassiopeia.  Along with the Heart Nebula (not seen here), it forms a famous nebula pair referred to as the Heart and Soul Nebula complex.  The nebula complex spans about 300 light years across and is a vast star-forming region illuminated by the light of young, nearby stars.  The stars in the region are less than a few million years old and are only beginning their life.  Click on the image to see a larger version.

California Nebula
The California Nebula is an emission nebula 1,000 ly from Earth in the constellation Perseus.  Its name comes from its shape, which resembles the state of California.  The nebula spans about 2.5 degrees in the sky.  The red color is "glowing" hydrogen gas that is being excited by the nearby energetic O7 star, Xi Persei, also known as Menkib, seen at the bottom.  Click on the image to see a larger version.

Ring Nebula
The Ring Nebula (M57) is a planetary nebula 2,500 ly from Earth in the constellation Lyra.  Planetary nebula form when a star nearing the end of its life expels a large amount of ionized gas before becoming a white dwarf.  The nebulosity seen here has been expanding for about 1,600 years.  The central star is about 60% the mass of our Sun and 200 times brighter in terms of its absolute magnitude.  It no longer produces its energy via nuclear fusion.  Click on the image to see a larger version.

Horsehead Nebula Region
The Horsehead Nebula is part of the Orion Molecular Cloud Complex about 1,375 ly from Earth in the constellation Orion.  The red/pinkish glow originates from hydrogen gas behind the dark nebula that is ionized by ultraviolet radiation from the nearby star Sigma Orionis (above horsehead not seen here).  The dark horsehead is caused by thick dust that blocks the light emanating from behind it.  Also seen is the Flame Nebula (red emission nebula on bottom left) and NGC 2023 (blue reflection nebula in bottom middle).  The bright blue star is Alnitak, the left most star in Orion's belt.  Click on the link to the right to see a larger version.

M45- The Pleiades
M45, also known as The Pleiades or The Seven Sisters, is an open star cluster 440 ly from Earth in the constellation Taurus.  The nine brightest stars are named after The Seven Sisters of Greek Mythology (Alcyone, Electra, Maia, Merope, Taygeta, Celaeno, Sterope) along with their two parents (Atlas, Pleione).  All are hot B-type stars.  The star cluster is illuminating a dust cloud through which it is passing creating a reflection nebulae.
