Nebula NGC 2170 in Unicorn - Nebula NGC 2170 in Monoceros - Nebula by reflexion located in the constellation Unicorn. This rich collection of predominantly reflection and sparse emission nebulosity exists in the western part of a vast star forming region known as the Mon R 2 association. The “” R”” designation stands for reflection and indicates an association of stars illuminating reflection nebulae. Most of the members of Mon R 2 are type B stars located along an east - west line stretching across 2 degrees of the winter sky, situated about 8 degrees east of the Orion Nebula. The Mon R 2 association resides at a distance of 830 pc and formed about 6 to 10 million years ago along the edge of the Mon R2 molecular cloud

Nebula by reflexion in NGC 6188 in the Altar - Reflection nebula in NGC 6188 in Ara - Nebula NGC 6188 is located about 4000 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope. The fainter stars here are cool, like those that orbit the inner 'bulge' of the Milky Way and appear slightly yellow on colour pictures. The foreground patch of dust that crosses this photograph must be illuminated by energetic radiation from stars that are much hotter than those in the background because hydrogen, which is associated with the dust, has been excited into a vivid red fluorescence by absorbing the invisible ultraviolet light. Here and there a few bright but cooler stars are caught up in the outskirts of dust clouds and some of their light is scattered to produce the blue reflection nebulae

Nebula Van den Bergh 93 (VdB 93) in Unicorn - Nebula Van den Bergh 93 (VdB 93) - VDB 93 is a star-forming region belonging to nebula IC 2177. The star SAO 152320, in the center of the image, illuminates this nebula located in the constellation Unicorn, about 4000 years old - light from Earth. Curtains of gas and dust dramatically open here to reveal the inner region of this starforming region. Unceremoniously named, bright star SAO 152320 shines with intense light in the center of this field. Clouds of gas glow strongly and dust shrinks quickly under its radiative prowess.

Nebula NGC 2170 in Unicorn - Nebula NGC 2170 in Monoceros - Nebula by reflexion located in the constellation Unicorn. This rich collection of predominantly reflection and sparse emission nebulosity exists in the western part of a vast star forming region known as the Mon R 2 association. The “” R”” designation stands for reflection and indicates an association of stars illuminating reflection nebulae. Most of the members of Mon R 2 are type B stars located along an east - west line stretching across 2 degrees of the winter sky, situated about 8 degrees east of the Orion Nebula. The Mon R 2 association resides at a distance of 830 pc and formed about 6 to 10 million years ago along the edge of the Mon R2 molecular cloud

Orion's Nebula - The Great Nebula in Orion - Located 1500 years ago - the light of the Earth, Orion's Nebula is the closest region to the formation of stars of the Sun. In its heart, a group of young stars called Orion's Trapeze. To the eye, the nebula appears as a misty patch around the central star of the line of three which form Orion's sword. The central group of stars is the Trapezium cluster and these stars are responsible for producing the nebula. It is the high concentration of dust and gas in this part of the sky which has resulted in the formation of the stars, so the Orion nebula is no random association of bright stars and dusty gas. At a distance of 1500 light years, the Orion nebula is the nearest star - forming region to the Sun

The bright, supergiant star at the centre of this nebula is known only by its catalog designation, HD 65750. The nebulosity around the star is the result of light reflected by dust surrounding it. The dust is thought to consist mainly of particles of silica condensed from material which the star is losing from its distended surface at a fairly steady rate. The rate of mass loss is much higher than in normal stars and is sufficient to produce the reflection nebula IC 2220. The stellar nature of the central object is revealed by the four diffraction spikes extending from it. These are artifacts due to structures within the telescope.

The Orion Nebula is famous for a number of reasons. It is the nearest bright nebula to us and can be seen with the naked eye. Its brightness led to it being the first nebula ever photographed (in 1882) and its proximity (1500 light years) means that we know more about it than any other star - forming region. It is also in a very active stage of star formation and it is perfectly placed for us to explore the intimate details of the birth of stars. The inner regions are glowing mainly in the red light of excited hydrogen, which together with some green emission from oxygen give the centre of the nebula a yellowish colour. The energy for this spectacular display comes from the small cluster of stars in the brightest part of the nebula. Three, five - minute exposures were used to make this pict

Open Cluster of Pleiades - The Pleiades star cluster - The Pleiades cluster is a cluster of about 500 young stars nees 150 million years ago. Visible in the constellation Taurus, this cluster is 440 years from the Earth. The Pleiades are one of the finest and nearest examples of a reflection nebula associated with a cluster of young stars. The cluster itself is a group of many hundreds of stars about 400 light years from Earth in the northern constellation of Taurus and has been recognised since ancient times. Seven of the brightest stars are quite easy to see with the unaided eye and bear the names of the Seven Sisters, the daughters of Atlas. The nebulosity seen here is light reflected from the particles in a cloud of cold gas and dust into which the cluster has drifted. It appears blue because these tiny interstellar particles scatter blue light more efficiently than the longer wavelengths of red light and it is streaky because of the distribution of dust particles in space

Nebula IC 2220 in the Carene - The IC 2220, nebula, deep image - This nebula is illuminated by a large red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. Many stars lose a substantial part of their mass as they age. The more massive the star, the greater the fraction of their substance is lost. Much material is ejected by intense stellar winds driven from the surface of extremely hot stars and the mass loss is often only detectable in the stellar spectrum. In cooler stars temperatures may be low enough for elements or simple compounds to form solid grains in the star's outer atmosphere. This is seen as dust, and sometimes there is enough to reflect the light of the star within. As is often the case with stellar outflows, the IC 2220 reflection nebula is bipolar, hinting at conditions near the surface of the central star

Visible in the constellation Taurus, this cluster is 440 years from the Earth. Brown dwarfs have been observed in this cluster. The Pleiades star cluster, also known as the Seven Sisters and Messier 45 (M45), is one of the brightest and famous star clusters visible in the northern hemisphere. It consists of about 500 bright, hot, young stars that were all born at the same time between 75 and 150 million years ago within a large cloud of dust and gas. The cluster contains many stars, of which only a handful are commonly visible to the naked eye. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars.

The cluster contains many stars, of which only a handful are commonly visible to the naked eye. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars. This star cluster lie some 440 light years away from the Earth, in the constellation of Taurus

Open Cluster of Pleiades - The Pleiades star cluster - The Pleiades cluster is a cluster of about 500 young stars nees 150 million years ago. Visible in the constellation Taurus, this cluster is 440 years from the Earth. The Pleiades are one of the finest and nearest examples of a reflection nebula associated with a cluster of young stars. The cluster itself is a group of many hundreds of stars about 400 light years from Earth in the northern constellation of Taurus and has been recognised since ancient times. Seven of the brightest stars are quite easy to see with the unaided eye and bear the names of the Seven Sisters, the daughters of Atlas. The nebulosity seen here is light reflected from the particles in a cloud of cold gas and dust into which the cluster has drifted. It appears blue because these tiny interstellar particles scatter blue light more efficiently than the longer wavelengths of red light and it is streaky because of the distribution of dust particles in space
