Nebula Trifide (M20) in the constellation Sagittarius - Trifid nebula (M20) in Sagittarius - View of the Trifide nebula (M20/NGC 6514) located in the constellation Sagittarius between 5000 and 10,000 years - light from Earth. Measuring some forty light years across, this nebula contains enough gas to make many thousands of suns. Within it a number of young hot stars have already formed. The hottest cause the gas, mostly hydrogen, to emit its characteristic red light. Around the red emission nebula the gas contains many dust grains which preferentially reflect the blue component of starlight. In some parts of the nebula there are so many dust grains that they hide the glowing gas, producing the three dark lanes which give the object its name. Trifid is located in Sagittarius constellation between 5000 and 10 000 light - years away

Omega nebula (M17) in Sagittarius - The Omega nebula (M17) in Sagittarius - View of the Omega nebula (M17/NGC 6618) located in the constellation Sagittarius at a distance of 5700 light years. This object derives its name from its looped shape reminiscent of the Greek letter when the nebula is seen in a telescope. The gas cloud is unusual in that it does not appear to be illuminated by the bright stars that commonly found in emission nebulae such as this. However, the nebulosity is very bright, so the exciting stars must be hidden within the cloud, an idea confirmed by the infrared brightness of the nebula. As well as exciting the nebula we can see, the embedded stars heat the dust that surrounds them, so M17 is one of the brightest objects in the infrared sky. It is about 6000 light years distant

This object derives its name from its looped shape reminiscent of the Greek letter when the nebula is seen in a telescope. The gas cloud is unusual in that it does not appear to be illuminated by the bright stars that commonly found in emission nebulae such as this. However, the nebulosity is very bright, so the exciting stars must be hidden within the cloud, an idea confirmed by the infrared brightness of the nebula. It is about 6000 light years distant

Nebula M78 in Orion - M78 nebula in Orion - The nebula M78 (NGC 2068) is located about 1300 years - light from Earth and extends over 4 years - light. M78, (NGC 2068) is part of the Orion complex, a large region of star - forming gas and dust centred around M42 and M43. It is the brightest diffuse reflection nebula in the sky, and fairly easy to see with binoculars (and almost visible to the naked eye, claim some observers). M78 is some 1600 light - years away and around 4 light - years across

Nebula Trifide (M20) in the constellation Sagittarius - Trifid nebula (M20) in Sagittarius - View of the Trifide nebula (M20/NGC 6514) located in the constellation Sagittarius between 5000 and 10,000 years - light from Earth. Measuring some forty light years across, this nebula contains enough gas to make many thousands of suns. Within it a number of young hot stars have already formed. The hottest cause the gas, mostly hydrogen, to emit its characteristic red light. Around the red emission nebula the gas contains many dust grains which preferentially reflect the blue component of starlight, and to the north (top) of the nebula can be seen a bright star which illuminates part of the dust to create a region of blue reflection. In some parts of the nebula there are so many dust grains that they hide the glowing gas, producing the three dark lanes which give the object its name. Trifid is located in Sagittarius constellation between 5000 and 10 000 light - years away

Nebula near the star S Mon in Unicorn - Fox Fur nebula in Monoceros - Nebula around the bright star S Monocerotis in the constellation Unicorn. S My belongs to a young cluster of stars located about 2600 years from Earth. The region around the 4.7 magnitude star S Mon is a fascinating mixture of red fluorescent hydrogen and dark, obscuring dust lanes. Some dust patches are close enough to bright stars to reflect light from them; these appear blue for the same reason that the day - time sky is blue - because some of the interstellar particles preferentially scatter blue light. The dust is mixed with gas and this affects the appearance of the emission nebulae, giving some of the faintest a curious 'fox fur' texture in this enhanced photograph. S Mon is part of a young open cluster of stars named NGC 2264 located about 2600 light years away, just north of the Cone nebula

Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. This dusty region is probably associated with the brighter and better - known Lagoon and Trifid Nebulae which are nearby in the sky and part of the same molecular cloud. The soft red glow of fluorescent hydrogen is evidence that there are young hot stars associated with the dusty clouds. These bright stars also illuminate the tiny solid particles, producing blue reflection nebulae bordering some of the emission regions. The dust is also evident in silhouette, both as sinuous dark lanes winding through the luminous gas and as the dark patches obscuring the ancient, yellow stars that populate the central parts of the Milky Way

Orion Nebula (M42 - 43) - The Orion Nebula - Located 1500 years ago - the Orion Nebula is the closest region to the formation of stars of the Sun. Image obtained with Siding Spring's 3.9m 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

Birth of stars in the nebula NGC 3372 - Star formation in the Carina Nebula - Detail of the Carene nebula (NGC 3372) obtained by the Hubble space telescope. The image shows a column of gas eroded by ultraviolet radiation emitted by young stars. Jets are also visible, showing the presence of emerging stars. NGC 3372 is located about 7500 light years away from Earth. The colors used in this image correspond to the emissions of different gases: sulfur in red, hydrogen in green and oxygen in blue. The NASA Hubble Space Telescope photograph captures the chaotic activity atop a three - light - year - tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks.

Image obtained by Siding Spring's 3.9m telescope. Vast clouds of hydrogen mixed with tiny dust grains are distributed throughout the Milky Way. The hydrogen can only be seen at visible wavelengths when it is illuminated by very hot stars. The light from these stars is sufficiently rich in ultraviolet light to cause the gas to glow with its characteristic red colour. In most cases, such as here, the hot stars formed recently from the hydrogen cloud. The stars found at the heart of the Trifid Nebula are here seen associated with dust lanes which are silhouetted against the glowing background. This nebula is in the constellation of Sagittarius at a distance between 5000 and 10,000 light years

Nebula NGC 3372 in the Carene - NGC 3372, Eta Carinae nebula - The nebula of the Carene is located about 8000 years - light from the Earth. It is home to many hot massive stars, including the star Eta Carinae in the centre of the nebula. This nebula is larger than the Great Nebula in Orion, but is not visible from most northern latitudes. It is a giant complex of emission and dark nebulae surrounding the unique variable star Eta Carinae, which scientists believe is the most massive and energetic star in the Milky Way galaxy. Located about 8,500 light years from the Earth, the star is about 100 times as massive as our own Sun, but produces 6 million times the light output. It was observed producing a remarkable burst of X - ray emissions that doubled its X - ray output in only four months. In the 1840's, Eta Carinae erupted visibly and was the second brightest star in the sky during this time

It is home to many hot stars, including the massive star Eta Carinae in the centre of the nebula. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. Although no bright naked - eye stars are associated with the Carina nebula now, 150 years ago there blazed forth here one of the most unusual and peculiar stars ever seen. The star is known as Eta Carinae and for a few months in 1843 it was the second or third brightest star in the sky. Since then it has faded and is today about 1000 times fainter than it was at its brightest as the nebula it created during its outburst has cooled and become opaque. The whole region around Eta Carinae is rich in hot stars of which Eta is an extreme example and it is their combined radiation that produces the spectacular Carina nebula that dominates this picture. The nebula and its peculiar star are about 8000 light years away

The central group of stars, the Trapezium cluster is hidden in the glow of the Orion Nebula in this photograph, but 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.

Eagle Nebula (IC 4703) and M16 star cluster in the Snake - The Eagle nebula in Serpens - The M16 star cluster is a cluster of young stars distant from 7000 years - light, formed about 2 million years ago in the Eagle nebula, IC 4703. These stars are much warmer than the Sun and can be 30 times more massive. Messier 16 is a cluster of young stars which formed about 2 million years ago from the gas and dust which still surrounds them. Brilliant blue stars of this type are much hotter than the Sun and can be up to thirty times more massive. The dark intrusions visible across the face of the nebula are condensations of dusty material which might one day collapse into yet more stars, should they survive the radiation from the bright stars, which is gradually etching them away. Bright red regions of photo - ionised hydrogen such as M16 are usually found in the spiral arms of galaxies and are often associated recent star formation. This example is about 7000 light years distant

Heart of the nebula NGC 3372 in the Carene - Eta Carinae and the Keyhole Nebula - The nebula of the Carene is located about 7000 years - light from the Earth. It is home to many hot stars, including the star Eta Carinae visible in the centre left of the image. Eta Carinae is a supermassive star (100 to 150 times the mass of the Sun). Image obtained by Siding Spring's 3.9m telescope. This wonderfully complex region at the heart of the NGC 3372 nebula was first described in detail by Sir John Herschel in 1838. He saw the bright circular shell visible in the upper part of the picture extending to the south to form a keyhole - shaped nebula. This luminous outline is no longer seen and the southern extension appears only as a dark dust cloud. It seems that the curious, explosively variable star Eta Carinae has enveloped itself in a cocoon of obscuring matter in the years since Herschel's observations and light from the star is no longer able to illuminate the rim of the dust cloud.

Nebula NGC 3372 in the Carene in fake colors - NGC 3372 Carina nebula in narrow band - The nebula of the Carene is located about 8000 years - light from Earth. It is home to many hot stars, including the massive star Eta Carinae in the centre of the nebula. Image obtained by the 1.2m Schmidt UK Telescope of Siding Spring through 3 different filters that highlight oxygen, hydrogen, and sulfur. Although no bright naked - eye stars are associated with the Carina nebula now, 150 years ago there blazed forth here one of the most unusual and peculiar stars ever seen. The star is known as Eta Carinae and for a few months in 1843 it was the second or third brightest star in the sky. Since then it has faded and is today about 1000 times fainter than it was at its brightest as the nebula it created during its outburst has cooled and become opaque. The whole region around Eta Carinae is rich in hot stars of which Eta is an extreme example and it is their combined radiation that produces the spect

Birth of stars in the nebula NGC 3372 - Star formation in the Carina Nebula - Detail of the Carene nebula (NGC 3372) obtained by the Hubble space telescope. The image shows a column of gas eroded by ultraviolet radiation emitted by young stars. Jets are also visible, showing the presence of emerging stars. NGC 3372 is located about 7500 light years away from Earth. The colors used in this image correspond to the emissions of different gases: sulfur in red, hydrogen in green and oxygen in blue. The NASA Hubble Space Telescope photograph captures the chaotic activity atop a three - light - year - tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks. This turbulent cosmic pinnacle lies within a tempestuous stellar nursery called the Carina Nebula, located 7,500 light - years away in the souther

Horsehead Nebula (B33) in Orion - Horsehead nebula in Orion - The horse head nebula, Barnard 33, is a dark nebula located in front of the IC 434 emission nebula about 1500 years - light of the Earth in the constellation Orion. Lower left is the reflexion nebula, NGC 2023. This curious dark nebula is one of the best - known images in astronomy, probably because of its chance likeness to a recognisable form. The horse - head shape is an extension of a large cloud of dust which fills the lower part (east) of the picture and hides the light of stars beyond. The outer surface of the dusty gas (IC 434) runs roughly north - south and is illuminated by sigma Orionis (off the top of the picture) which causes the hydrogen there to fluoresce, outlining the horse - head shape. The diffuse haze to the left of the image (north) is scattered light from the bright star zeta Orionis. Though conspicuous here, the Horsehead is very difficult to see visually, even with a large telescope. A bright star is
