Nebulae IC 1283 - 84 and NGC 6589 - 90 in Sagittarius - Nebulosity in Sagittarius, NGC 6589 - 90 - These nebulae are located in Sagittarius at a distance of about 5900 light years from Earth. Image made with Siding Spring's 3.9m telescope. Our view towards the centre of the Galaxy is obscured by extensive clouds of interstellar dust in the direction of the constellation of Sagittarius. The large - scale, patchy nature of the obscuration can be seen with the unaided eye and it is evident on smaller scales from the uneven distribution of background stars across this picture. Light from bright stars within the dust produces the two blue reflection nebulae (NGC 6589 and 6590), and these stars are members of a loose open cluster of stars, NGC 6595 (Sharpless 37) which is at a distance of about 5,900 light years. A large, almost transparent cloud of hydrogen, mixed with traces of dust, glows with a characteristic magenta hue over most of the field of view. This is known as IC 1283, 1284 and 4700 and is likely at a similar distance to NCC 6595

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 NGC 6188 in the Altar - The NGC 6188 nebula and NGC 6193 in Ara - Nebula NGC 6188 is located about 4000 years from Earth. It is home to a cluster of young stars NGC 6193, formed three million years ago. Image obtained by Siding Spring's 3.9m telescope. Here we see two bright stars whose radiant energy is beating down on to the surface of a dark cloud, very similar to the Horsehead in Orion. The cloud itself is opaque and because of that, very cold inside. These conditions are ideal for the formation of organic molecules on the surfaces of the chilled dust particles. The opacity of the cloud protects the fragile molecules within from the energetic radiation of nearby stars, but as its surface is gradually warmed and eroded, the delicate organic molecules are destroyed and the hydrogen released glows as a distinctive red emission nebula

These cold gas columns are home to star embryos. The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula's Pillars of Creation. This image shows the pillars as seen in visible light, capturing the multi - coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust - colored elephants trunks of the nebula's famous pillars. The dust and gas in the pillars is seared by the intense radiation from young stars and eroded by strong winds from massive nearby stars. With these new images comes better contrast and a clearer view for astronomers to study how the structure of the pillars is changing over time.

In yellow, near-infrared images obtained by the Hubble Space Telescope; in red, infrared images obtained by the Spitzer Space Telescope; in blue and purple, X-ray observations obtained by the Chandra Space Telescope. Nasa's Great Observatories - the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory - have collaborated to produce an unprecedented image of the central region of our Milky Way galaxy. In this spectacular image, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the galaxy is located within the bright white region to the right of and just below the middle of the image. The entire image width covers about one-half a degree, about the same angular width as the full moon. Each telescope's contribution is presented in a different color: - Yellow represents the near-infrared observations of Hubble. These observations outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars. - Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments. - Blue and violet represent the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy's center. The bright blue blob on the left side is emission from a double star system containing either a neutron star or a black hole. When these views are brought together, this composite image provides one of the most detailed

Cocoon Nebula (IC 5146) in Swan - Cocoon Nebula - IC 5146 - in Cygnus - The Cocon Nebula, IC 5146, is an emission nebula located about 4000 years from Earth in the constellation of Swan. This complex mass of molecular hydrogen and dust, located 4,000 light years from earth, glows red by emitting light, shines blue by reflecting light and exhibits a pattern of dark lanes that result when dust absorbs light. Much of the light seen in the main part of this nebula is generated by the massive bright star near it's center. The Cocoon is a stellar nursery containing a relatively young open cluster of stars with several individual constituents that are newly formed. Wide angle, long exposure photographs reveals the nebula to be very extensive - essentially a vast river of interstellar dust

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

Nebulae NGC 6334 and NGC 6357 in Scorpio - Nebulae NGC 6334 and NGC 6357 in Scorpius: These nebulae are located about 5500 light years from Earth - Located in the constellation of Scorpius, the Cat's Paw Nebula resemble a faint, luminous paw-print on the sky. Deep images reveal that the nebula is about a degree across in the sky. At a distance of about 5500 light-years away it is a truly vast structure spanning almost 100 light-years across. The sculpted gases of NGC 6334 are illuminated by the light of numerous powerful stars, some exceeding 10 solar masses. The two brilliant blue stars in the upper left are Lambda and Kappa Scorpii. Many of these luminous hot stars are surprisingly not visible because they lie within the dusty plane of our galaxy. At infrared wavelengths the numerous hot stars are revealed and the nature of this object as a region of massive star formation becomes clear. In the past decade water masers, molecular outflows, and x-ray sources have provided direct evidence of clusters of protostars within NGC 6334. The nebula was discovered by John Herschel in 1837, and the brief and uninformative description in his Cape Observations catalog is a testament to its faintness. The ruddy hue of this complex is the result of the absorption of blue light by the ubiquitous dust clouds along our line of sight in the plane of the Milky Way. The red, intricate bubble making up the left paw print is particularly striking and is most likely either a star expelling large amounts of matter at high speed as it nears the end of its life or the remnant of a recent supernova - Located near the famous “” Cat Paw”” nebula (NGC 6334), the Stellar Cluster Pismis 24 lies at the core of NGC 6357. Its stars include some of the most massive stellar behemoths known. One of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered by the Hubble Telescope to b

Nebula NGC 6334 in the Scorpion - The 'reddened' nebulosity of NGC 6334 - The nebula NGC 6334 is located about 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebula NGC 6334 shows no evidence of a blue component in their colour - indeed, the blue - light plate used in these 3 - colour pictures had no nebulous image at all - nor is there any obvious sign of the bright blue stars normally found in these objects. They are excellent examples of the phenomenon known as 'interstellar reddening', the selective removal of blue light by minute particles of dust in the line of sight. This accounts for both the ruddy hue and apparent absence of blue stars. The hot stars are present but only some of the red part of their light is seen so they are not conspicuous. This nebula is quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Careful measurement of the colour of stars associated with the nebula indicate that they are dimmed by a factor of about 10 in the green part of the spectrum, much more in the blue, but relatively little at red wavelengths. Some care has been taken to ensure that these images are as close to true - colour as possible

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

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.

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 NGC 6559 in Sagittarius - NGC 6559 and IC 1274 - 75 in Sagittarius - Located in Sagittarius, this nebula is located at a distance of about 5000 years - light from Earth. 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

Nebula IC 1318 in the Swan - IC 1318 the Butterfly nebula in Cygnus - IC 1318 is a very extended emission nebula that surrounds the star Gamma Cygni (Sadr), visible towards the middle of the image. LDN 889 is a vast region of dark nebulae that separates the nebula on the left from Sadr. On the extreme right, another dark nebula, B343. This is a large area of emission nebulosity around Sadr, Gamma Cygnii, the brightest star in this photo and the heart of Cygnus. Stretching more than 2 x 3 degrees here, the nebulosity actually extends far out of the photo. Most of the nebulosity is fairly faint, but brighter patches can be seen in a modest instrument. The two sections of nebulosity to the left of Gamma are called the Butterfly Nebula and have the catalog designation of IC 1318. LDN 889 is the large area of dark nebulosity that separates the two halves of the Butterfly Nebula, and B 343 is the small but very dense dark nebula on the right side of the image

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

Orion's Nebula - The Great Nebula in Orion - Located 1500 light years from 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

Nebulae IC 1283 - 84 and NGC 6589 - 90 in Sagittarius - Nebulosity in Sagittarius, NGC 6589 - 90 - These nebulae are located in Sagittarius at a distance of about 5900 light years from Earth. Image made with Siding Spring's 3.9m telescope. Our view towards the centre of the Galaxy is obscured by extensive clouds of interstellar dust in the direction of the constellation of Sagittarius. The large - scale, patchy nature of the obscuration can be seen with the unaided eye and it is evident on smaller scales from the uneven distribution of background stars across this picture. Light from bright stars within the dust produces the two blue reflection nebulae (NGC 6589 and 6590), and these stars are members of a loose open cluster of stars, NGC 6595 (Sharpless 37) which is at a distance of about 5,900 light years. A large, almost transparent cloud of hydrogen, mixed with traces of dust, glows with a characteristic magenta hue over most of the field of view. This is known as IC 1283, 1284 and 4700 and is likely at a similar distance to NCC 6595

Light from bright stars within the dust produces the two blue reflection nebulae (NGC 6589 and 6590), and these stars are members of a loose open cluster of stars, NGC 6595 (Sharpless 37) which is at a distance of about 5,900 light years. A large, almost transparent cloud of hydrogen, mixed with traces of dust, glows with a characteristic magenta hue over most of the field of view. This is known as IC 1283, 1284 and

Nebula NGC 7635 in Cassiopee - Bubble Nebula (NGC 7635) in Cassiopeia - This nebula is located about 7100 years - light from Earth. A massive star, called Wolf - Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522. The Bubble Nebula in Cassiopeia is one of the most dramatic emission nebulae visible in the northern hemisphere. Lying at a distance of about 7,000 light - years away and spanning six light - years in diameter, NGC 7635 is quite bright with a magnitude of 7.0. The star in the middle of the bubble, BD+602522, is responsible for this stunning site, for this very hot star emits so much UV radiation that it is able to also heat and excite the surrounding dust and gas, thus emitting its own radiation. It is a Wolf - Rayet star, a very luminous star and also very short - lived. This Wolf - Rayet star is 40 times as massive than our sun

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

Nebula NGC 3372 in the Carene - The Carina nebula, NGC 3372 - The Carene nebula is located about 7000 years from the Earth. It is home to many hot stars, including the star Eta Carinae in the centre of the nebula. Image obtained by Siding Spring's 3.9m telescope. The brightest part of the Milky Way, as seen by the unaided eye, lies in the southern constellation Carina. Here there are an unusually large number of young, hot stars. Their radiation is rich in energetic ultraviolet light. Many of these stars were born within the spectacular Carinae nebula, seen here. The nebula is a cloud of glowing gas composed mostly of hydrogen. It excited by ultrviolet light from the embedded stars. This dostictive emission radiation is responsible for the red colour. About a quarter of the nebula is made of helium gas, the second most abundant element in the universe after hydrogen, and all the other chemical elements account for only a few percent of the total mass. The brightest star in the nebula is known as eta Carinae. This remarkable object is one of the most luminous and most massive stars known

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 picture using the Anglo - Australian Telescope at Siding Spring

The Omega nebula (M17) seen in infrared - M17 nebula in infrared - The Omega nebula (M17) seen in infrared by the Spitzer space telescope. M17 is a star-forming region about 6000 light years ago in the constellation Sagittarius. In the center of the nebula is a group of massive stars. The dust appears in red, the hot gas in green, the regions or this gas and the dust mixes in white. Nasa's Spitzer Space Telescope has captured an infrared view of the star - making cloud called M17, or the Swan nebula. The cloud, located about 6,000 light - years away in the constellation Sagittarius, is dominated by a central group of massive stars - - the most massive stars in the region. These central stars give off intense flows of expanding gas, which rush like rivers against dense piles of material, carving out the deep pocket at center of the picture. Winds from the region's other massive stars push back against these oncoming rivers, creating bow shocks like those that pile up in front of speeding boats. Three of these bow shocks are nestled in the upper left side of the central cavity, but are difficult to spot in this view. They are composed of compressed gas in addition to dust that glows at infrared wavelengths Spitzer can see. The smiley - shaped bow shocks curve away from the stellar winds of the central massive stars. This picture was taken with Spitzer's infrared array camera. It is a four - color composite, in which light with a wavelength of 3.6 microns is blue; 4.5 - micron light is green; 5.8 - micron light is orange; and 8 - micron light is red. Dust is red, hot gas is green and white is where gas and dust intermingle. Foreground and background stars appear scattered through the image

Elephant tube nebula (VDB 142) in Cephee - The Elephant Trunk Nebula (VDB 142) in Cepheus: IC1396, VDB 142. Nebula located about 2700 light years from Earth. Image obtained with a bezel Tele Vue NP127iS, through 3 different filters that demonstrate oxygen, hydrogen, and sulfur - The Elephant Trunk Nebula (IC 1396A) in Cepheus is part of the larger IC 1396 complex which spans a large area of the sky measuring 170 by 140 arc-minutes and is one of the brightest emission nebulae with a magnitude of 3.5. The western portion of IC 1396 contains the Elephant Trunk Nebula (IC 1396A) which is characterized with H-II emissions, dark lanes and globules as well as a small reflection nebula. The IC 1396 complex is technically a star cluster (aka Cr 439, Trumpler 37) owing to the presence of a developing open but loose cluster at the heart of this rich nebulosity. This open star cluster is comprised of 50-100 member stars which vary in brightness spanning an area of approximately 50 'in diameter and which are not very well detached from the background sky. This stellar nursery lies at a distance of 2,720 light-years away - Image taken in combining the light from 3 different filters tracing emission from oxygen, hydrogen, and sulphur

Nebula Sh2 - 106 in the Swan - Sh2 - 106 nebula in Cygnus - Sharpless 106 (Sh2 - 106) is a star-forming region in the constellation Swan. Image obtained by Hubble Space Telescope (HST) and Subaru Telescope. The bipolar star - forming region, called Sharpless 2 - 106, or S106 for short, looks like a soaring, celestial snow angel. The outstretched “” wings”” of the nebula record the contrasting imprint of heat and motion against the backdrop of a colder medium. Twin lobes of super - hot gas, glowing blue in this image, stretch outward from the central star. This hot gas creates the “” wings”” of our angel. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an “” hourglass””” shape. This composite image combines optical and near - infrared astronomical data from the Hubble Space Telescope with mid - infrared data from the ground - based Subaru Telescope, located on Mauna Kea in Hawaii. The Hubble data (H - alpha, J, and H) were taken as part of Hubble Heritage observations of S106 in February 2011. The Subaru data were obtained in May 1999

Nebulae NGC 6334 and NGC 6357 in Scorpio - Nebulae NGC 6334 and NGC 6357 in Scorpius - These nebulae are located approximately 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebulae NGC 6334 and NGC 6357 show no evidence of a blue component in their colour - indeed, the blue - light plate used in these 3 - colour pictures had no nebulous image at all - nor is there any obvious sign of the bright blue stars normally found in these objects. They are excellent examples of the phenomenon known as 'interstellar reddening', the selective removal of blue light by minute particles of dust in the line of sight. This accounts for both the ruddy hue and apparent absence of blue stars. The hot stars are present but only some of the red part of their light is seen so they are not conspicuous. These nebulae are quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Careful measurement of the colour of stars associated with the nebulae indicate that they are dimmed by a factor of about 10 in the green part of the spectrum, much more in the blue, but relatively little at red wavelengths. Some care has been taken to ensure that these images are as close to true - colour as possible

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 partially enveloped in the dust cloud and its scattered light is seen as the large, irregular blue reflection nebula, NGC 2023. All these objects are about 1500 light years distant
