Tarantula Nebula (NGC 2070) in the river bream - The Tarantula Nebula, around the 30 Dor cluster - The Tarantula Nebula (or 30 Bream) is the largest star-forming region of the Great Magellan Cloud. It is located 170,000 light years ago in the constellation Dorado (southern hemisphere). At the center of this nebula, the open cluster of R136 stars, clusters of hot and massive stars. Image obtained with Siding Spring's 3.9m telescope. This object is the only extra - galactic nebula which can be seen with the unaided eye. It is a faint patch of light at the eastern end of the Large Magellanic Cloud, 170,000 light years distant. A small telescope reveals narrow spindly tendrils of glowing gas which have been likened to the legs of a spider. The 'body' of the spider is the bright nebula seen at the centre of the photograph, while at its core is an extremely dense clump of very hot stars, until recently thought to a single, unusually massive star known as 30 Doradus. The very hot stars of 30

Star cluster in the nebula NGC 3603 - Star cluster in NGC 3603 nebula - Cluster of young stars in the nebula NGC 3603, located about 20,000 years ago - light from Earth in the southern constellation of Carene. Image obtained by the Hubble Space Telescope in August and December 2009. NGC 3603 is a prominent star - forming region located in the Carina spiral arm of the Milky Way, about 20,000 light - years away from our Solar System. This image from the NASA/ESA Hubble Space Telescope shows a young star cluster surrounded by a vast region of dust and gas. Most of the bright stars in the image are hot blue stars whose ultraviolet radiation and violent winds have blown out an enormous cavity in the gas and dust enveloping the cluster. This Hubble Space Telescope image was captured in August 2009 and December 2009 with the Wide Field Camera 3 in both visible and infrared light, which trace the glow of sulfur, hydrogen, and iron

Nebula Trifide (M20) in the constellation Sagittarius - Trifid nebula (M20) in Sagittarius - View of the Trifide nebula (M20 or NGC 6514) located in the constellation Sagittarius between 5000 and 10,000 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope. Trifid nebula is located in Sagittarius constellation between 5000 and 10 000 light - years away. Stars, the Sun included, were born within clouds of dusty gas such as the Trifid Nebula. 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 gi

Spiral galaxy NGC 2997 in the Pneumatic Machine - Spiral galaxy NGC 2997 in Antlia - NGC 2997 is a spiral galaxy distant about 55 million years - light. NGC 2997 seems to be a galaxy seen from the front but in reality is inclined by about 45 degrees. Its arms are home to large star-forming regions while its core is surrounded by much older yellow stars. The disc of NGC 2997 is inclined at about 45 degrees to our line of sight, revealing its internal structure and giving the galaxy an oval appearance. Like most spirals, the galaxy has two prominent spiral arms, which appear to originate in the yellow nucleus, are peppered with bright red blobs of ionised hydrogen which are similar to regions of star formation in our own Milky Way. Within these gas clouds are produced the hot blue stars which generate most of the light in the arms of the galaxy. A much older population of yellowish stars are concentrated around the nucleus.

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

Nebula IC 2220 in the Carene - A mass - loss star in IC 2220 - This nebula is illuminated by a giant red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. 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 light from the star has also produced the annular halation ring (a photographic artefact) that ornaments the nebula. These features, real or otherwise, have provoked the name '

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

March -View of the south pole - Mars South Pole: Image of the southern polar cap of Mars obtained by the Mars Express probe on December 17, 2012. The bright white region of this image shows the icy cap that covers Mars' south pole, composed of frozen water and carbon dioxide. The southern cap reaches some 3 km thick in places, and is around 350 km in diameter. This icy region is permanent; in the martian winter another, thinner ice cap forms over the top of it, stretching further out across the planet and disappearing again when the weather warms up. Mars Express imaged this area of March on 17 December 2012, in infrared, green and blue light, using its High Resolution Stereo Camera.

Eagle Nebula (IC 4703) and M16 star cluster in the Snake - M16, The Eagle Nebula in Serpens - The M16 star cluster is a cluster of young stars 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. Image obtained by combining light through 3 different filters that highlight oxygen, hydrogen, and sulfur. 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.

Image obtained by Siding Spring's 3.9m telescope. The stars that excite this unusual nebula, NGC 3576, are not visible on this photograph. They are hidden in the dusty cloud at the 'base' (south) of the huge loops of nebulosity. This is material that has been blown out by radiation pressure and stellar winds from the concealed stars. Silhouetted against the tenuous loops are dark clouds of dust with bright rims which indicate the direction of the stars which excite the nebula.

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

Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula M57 in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. Image obtained by the Hubble Space Telescope. This close - up, visible - light view by Nasa's Hubble Space Telescope reveals new details of the Ring Nebula. The object is tilted towards Earth so that astronomers see the ring face - on. The Hubble observations reveal that the nebula's shape is more complicated than astronomers thought. The blue gas in the nebula's center is actually a football - shaped structure that pierces the red doughnut - shaped material. Hubble also uncovers the detailed structure of the dark, irregular knots of dense gas embedded along the inner rim of the ring. The knots look like spokes in a bicycle.

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 constellation is small but distinctive. The conspicuous globular cluster NGC 6723 is at the western (right) edge of the photograph, but it is in Sagittarius, and is about 30,000 light years distant. Our picture is about 4.5 degrees across and the extremely faint Corona Australis nebula meanders along the Sgr - CRA border nebula in the same E - W direction. Almost all the nebulosity here is starlight, reflected from minute grains of dust, some of which gather into darker condensations ('molecular clou

Paranal Observatory - Chile - Paranal Observatory - Chile - The lactee road above the Paranal Observatory in Chile. 360 degree Panorama of ESO - Paranal Observatory platform. The four 8m (UT) and four 1.8 m (AT) diameter telescopes of the VLT are all observing under the Milky Way arch during this very dark Southern hemisphere spring night. The large (LMC) and small (SMC) Magellanic clouds are visible to the left of the picture while another galaxy, Andromeda Galaxy (M31) is also visible just to the right of UT4. Bright Jupiter is high in the sky. The picture also shows two 'astronomical' lights, the zodiacal light crossing the Milky Way center vertically (just at the left of the middle of the image, above AT3) and the Gegenschein, usually very difficult to observe, below Jupiter on the right hand side of the image

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

Nebula N44 in the Large Magellan Cloud - Superbubble LHA 120 - N 44 in the Large Magellanic Cloud - This image obtained by the Very Large Telescope (VLT) shows the nebula N44 surrounding the cluster of stars NGC 1929. It is a star-forming region located in the galaxy of the Great Magellan Cloud, about 170,000 light years from Earth. Eso's Very Large Telescope captured this striking view of the nebula around the star cluster NGC 1929 within the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. A colossal example of what astronomers call a superbubble dominates this stellar nursery. It is being carved by the winds from bright young stars and the shockwaves from supernova explosions. This nebula is officially known as LHA 120 - N 44, or just N 44 for short. Hot young stars in NGC 1929 are emitting intense ultraviolet light and causing the gas to glow. This effect highlights the aptly - named superbubble, a vast shell of material around 325 by 250 light - years across. For c

Spiral galaxy NGC 5248 in Bovier - Spiral galaxy NGC 5248 in Botes - NGC 5248 is a spiral galaxy located about 50 million years ago - light. It belongs to the Virgin's galaxy cluster. NGC 5248 is a spiral galaxy that is part of the Virgo Cluster: however on a star chart the galaxy is found to be within constellation boundaries of Bootes. Short exposures of this galaxy show the bright structures of the central regions. Many dust lanes, HII (red) regions, and blue stellar associations populate this busy area. Deeper exposures such as the image to the left begin to show the two tenous and dim outer arms of the galaxy. This galaxy seems to be a mix between M81 with two distinct arms and M100 with detailed nucleus. NGC 5248 is estimated to be 50 million light years away

Dark Nebula in Scorpio - A dark cloud in Scorpius - This dark nebula is located about 5000 years from Earth. Image obtained by Siding Spring's 3.9m telescope. This curious un - named nebula is governed by radiation from very luminous stars some distance from the nebula. The direction of the radiation source can be seen from the flow pattern in the dark cloud and the extensive bright red rims at the end of the nebula that is exposed to radiation from the hot stars. This part of the nebula is reminiscent of the famous Horsehead nebula in Orion, which is also the consequence of starlight destroying a dark cloud. The source of the energy here is the Scorpius OB association, a group of brilliant, very hot stars, about 5000 light years away from us

Around the Baade window - The Baade's window region - The Baade Window (at the bottom right of the Gamma star of Sagittarius, the brightest of this image) is a region of the Lactee Way in the constellation of Sagittarius containing little interstellar dust. This region, named in reference to the astronomer Walter Baade, allows astronomers to have a more degagee view of the center of our galaxy. The Baade window, (at the bottom right of the bright star close to the center of this image), is a region of the Milky Way, in the Sagittarius constellation, with relatively little interstellar dust along our line of sight. It is therefore really a unique 'window' through which the astronomers can observe the Milky Way galactic Bulge, only a few degrees from the galactic center. The 'line of sight' through this 'window' passes 1800 light year nearby the Milky Way heart. This region of the sky was named after German astronomer Walter Baade
