Proxima Star of Centauri - Proxima Centauri - Proxima of Centaur (in the center of the image) is the closest star to the Sun, at a distance of 4.2 years - light. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. Proxima Centauri is the nearest known star to the sun, at a distance of about 4.2 light years. It is an intrinsically faint red star, more than ten magnitudes (ten thousand times) fainter than the Sun. It is also much cooler, with a surface temperature of about 3100 C. Its visual (apparent) magnitude is eleven, so it is only visible with a good telescope, and only then from southern latitudes. Proxima is about one - tenth the mass of the sun, which accounts for its low surface temperature. It is possibly an outlying member of the triple alpha Centauri system just a few light days closer to us than the other, much brighter stars in the group

Motion of the Star Proxima of Centauri - The proper motion of Proxima Centauri - Proxima of Centauri (in the center of the image) is the closest star to the Sun, located at a distance of 4.2 years - light. This star is a red dwarf, 10,000 times less luminous than our Sun, and is invisible to the naked eye. Its proximity makes it move quickly ahead of the other stars. This composite image made from three images taken in 1976 (blue), 1982 (red) and 1993 (green) shows the shift of the star in 17 years. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. Proxima Centauri is the nearest known star to the sun, at a distance of about 4.2 light years.

Open cluster NGC 4755 - Jewel Box - The Jewel Box cluster, NGC 4755 - NGC 4755 is located in the constellation of the Southern Cross at a distance of 7800 years - light from Earth. The bright orange star is Kappa Crucis, a supergiant red star. This famous group of young bright stars is an open cluster some 7800 light years from the Sun. It was named the Jewel Box from its description by Sir John Herschel as 'a casket of variously coloured precious stones', which refers to its appearance in the telescope. The bright orange star is kappa Crucis, and it contrasts strongly against its predominantly blue, hot companions. Kappa Cru is a very large, (hence very luminous) quite young star in its red supergiant stage, which paradoxically indicates that its life is drawing to a close. The cluster is looks like a star to the unaided eye and appears close to the eastern - most star of the Southern Cross, so is only visible from southern latitude

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

Open cluster NGC 3293 in Carene - Open star cluster NGC 3293 in Carina - Star cluster located in the constellation Carene about 8500 years ago - light from Earth. Unlike the Sun, many stars are found in brilliant clusters such as NGC 3293 where they spend their lives. At birth, which should have been at much the same time for all the stars in NGC 3293, the most massive stars are hot and very luminous and therefore appear as the brightest blue stars. With time they deplete their supplies of nuclear fuel, hydrogen. This evolutionary process involves cooling, so that the stars become redder, and would ordinarily disappear from view, but they also swell to gigantic proportions and so remain visible. The bright orange star in NGC 3293 is the member of the cluster which has aged fastest. This cluster is in the constellation of Carina at a distance of about 8500 light years

Image obtained by the 3.9m telescope of Siding Spring In March, 1871 Charles Messier noted as number 93 in his famous catalogue this conspicuous group as a cluster of small stars. It was one of the last objects that Messier himself listed though he lived until 1817. The cluster is in the southern constellation of Puppis (known to Messier as Argo Puppis) and is in a rich part of the Milky Way, almost on the Galactic equator. The group is quite compact and is on the threshold of naked - eye visibility under good conditions. It is at a distance of over 3000 light years.

Open cluster M11 in the ECU of Sobieski - M11 open cluster in Scutum - M11 (NGC 6705) is a cluster of about 3000 stars. Image obtained by Siding Spring Clusters of bright blue stars like M11 are found scattered among the spiral arms of the Milky Way and other galaxies like it. They are a clear sign that star formation is active, because such clusters are usually very young and short lived. The stars in M11 all formed from the same material and at about the same time, a few million years ago. In 100 million years or so, all the brightest stars in the group will have evolved into cool supergiants and exploded as supernovae, leaving behind large numbers of low mass, relatively faint stars whose lives will be much longer and whose end will be much less dramatic. Located in the constellation of Scutum, it is sometimes mistaken for a loose globular cluster. M11 is also called the “” Wild Duck Cluster”” because of it's resemblance to a flight of wild ducks when viewed in a telescope. M11, wit

Sometime during 23 February 1987 a supernova exploded in the Large Magellanic Cloud (LMC), a nearby galaxy. However, the LMC is about 170,000 light years distant, so the supernova exploded 170,000 years ago. It was discovered the following day and brightened rapidly to become the first supernova to be easily visible to the unaided eye for almost 400 years.

Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars. As the rapidly moving blast wave encounters the relatively stationary interstellar medium it creates a very narrow, luminous shock front that appears as a faint nebula. Because the shock front is very convoluted the nebulosity appears to be highly structured and the various colours define different energy levels within the interaction.

This unusual barred spiral galaxy is in the far southern constellation of Volans and was discovered by Sir John Herschel who described one of its spiral arms as hook - like. Although not seen here, (but evident on very deep images) NGC 2442 appears to have a less massive, distant companion that is also distorted, and it seems likely that the two have had a close encounter in the recent past. If there are no further meetings, the forces that hold NGC 2442 together will restore galaxy to a more symmetrical spiral form. However, much more likely is that the companion has been captured by the distorted spiral and will eventually be devoured by it, triggering a dramatic bout of star formation. NGC 2442 is about

Galaxy NGC 4027 in the Raven - Galaxy NGC 4027 in Corvus - NGC 4027 is a spiral galaxy located about 80 million years ago - light. One of his arms is more extended, probably by the presence of a nearby dwarf galaxy. Image made with Siding Spring's 3.9m telescope. This galaxy is of interest because of its similarity to the Large Magellanic Cloud, (LMC) our nearest extra - galactic neighbour. Like the LMC, its light comes predominantly from young stars, which are hotter than the Sun and give the galaxy a bluish colour. However, because this galaxy is over 80 million light - years distant we see only the integrated light of millions of unresolved stars, rather than the individuals we see in the LMC. NGC 4027 has a somewhat distorted appearance and an elongated spiral arm, probably due to the gravitational effect of a smaller companion galaxy, not visible in this photograph but rather obvious on a much deeper image. NGC 4027 is less than half a degree south of the Antennae interacting gala

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

Eagle Nebula (IC 4703) and M16 star cluster in the Snake - The dust lanes in Messier 16 (NGC 6611) - Located in the Snake, this nebula is about 6000 years away from Earth. The M16 star cluster is a cluster of young stars 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 made with Siding Spring's 3.9m telescope. There are few clearer examples anywhere of the intimate relationship between dust, gas and young stars than M16. We see a young cluster of stars (NGC 6611) which formed about 2 million years ago, illuminating a cloud of hydrogen gas. The gas is also dusty, and in places the dust is dense enough to prevent starlight from reaching the gas and making it glow with its distinctive red hue. The luminous hydrogen provides a vivid background against which are seen numerous dark lanes and discrete globules of dust. Many of the dusty clouds are edged with bright rims which indicate the direction

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

Towards the center of the nebula, a cluster of blue stars, NGC 2244 formed less than a million years ago. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. The Rosette Nebula exhibits a striking circular symmetry which gives it the appearance of a partly opened rose, an allusion further enhanced by the rich red hues seen in this colour photograph. Near the centre of the nebula is a cluster of blue stars catalogued as NGC 2244. These stars are responsible for making the nebula visible and for creating the hollowed - out central cavity. This cluster of stars formed from the gas which now surrounds it less than a million years ago and is thus very young on the cosmic timescale.

Image obtained by Siding Spring's 3.9m telescope. 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. Some of the wispy tendrils of nebulosity are Herbig - Haro objects, jets of matter ejected from newly - formed stars still hidden within the nebula.

Nebula NGC 3372 in the Carene - The Carina nebula - The Carene nebula is located about 8000 years from the Earth. 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 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

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.

Image obtained from the 3.9m telescope of Siding Spring The peculiarity of NGC 5189 lies in its astonishingly complex structure, first noted by Sir John Herschel, who discovered it in 1835. Seen through the telescope it seems to have an 'S' shape, reminiscent of a barred spiral galaxy, hence its popular name. This is seen in the colour photograph as the central greenish part. Deep photographs such as this show many filaments, rather more reminiscent of the Crab nebula, a supernova remnant, than a planetary nebula. Unlike the Crab nebula, NGC 5189 is remarkably symmetrical. Distances to planetary nebulae are notoriously difficult to measure, but this one is estimated to be about 3000 light years away

They are probably caused by opaque clouds of dust passing between the hidden star and the outskirts of the nebula we see, the moving shadows changing the apparent form of the glowing dust in an irregular way. This picture was made from three AAT plates taken over several y

Nebula of the cone NGC 2264 in the Unicorn - The Cone Nebula in Monoceros - Region H II located about 2600 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope. The Cone nebula is part of an enormous cloud of hydrogen and tiny solid particles associated with the loose open cluster, NGC 2226 in the equatorial constellation of Monoceros. Within and around this cloud are many recently formed stars, some completely hidden within the dense interstellar matter. They can be detected by special infra - red techniques which are able to penetrate the obscuration. The largest of the dust clouds is the curious straight - sided feature which gives this object its name

The curious looped nebula NGC 3576 is about 7000 light years from us while its neighbour NGC 3603 is more than twice as far away. That NGC 3603 is the more distant is confirmed by its colour, which is a ruddier red than the pinkish hue of NGC 3576. The change in colour is due to absorption of the blue - light component of the nebulosity by dust particles in the much longer line of sight. This effect is known as interstellar reddening, though it would be better described as 'de

Nebula NGC 6164 - 5 in the Rule - The field around NGC 6164 - 65 - This nebula is located about 4000 years from Earth. It's a bipolar nebula around a hot O star at the end of life. Image obtained by Siding Spring's 3.9m telescope. Very hot, massive stars lose substantial amounts of matter from their surfaces during much of their brief lives. Mass - loss is usually a fairly steady process but some stars occasionally develop instabilities and have major outbursts. This star has thrown off at least two distinct lots of material during its lifetime, the brightest and most recent being the bright lobes of NGC 6164 - 5 at the centre of the picture while a much fainter rim of nebulosity can be seen at a considerable distance from the central star, indicating an earlier episode of violent ejection. The nebula is at a distance of about 4200 light years

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

Dark Nebula in Scorpio - A dark cloud in Scorpius, wide field - 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

NGC 6822 is a nearby irregular galaxy reminiscent of the Large Magellanic Cloud (LMC). Like the LMC it contains many, extremely hot stars of the Wolf - Rayet type, stars which often have intense stellar winds blasting from their surfaces. Small groups of such stars are found at the centres of the bubble nebulae seen here, which are the result of the stellar winds colliding with the more or less stationary interstellar medium in NGC 6822. At the interface of the collision, the interstellar medium glows, producing a thin, luminous bubble.

Despite the longevity of their parent stars and the very brief lifetime of the nebula (typically less than 100,000 years) such sights are common because sun - like stars are common. The nebula has nothing to do with planet formation, indeed the formation of the nebula would effectively destroy any planets the parent star had, rather the name refers to the telescopic appearance of the nebula. Some planetaries are very bright and their discs look like solar system planets. A close look at this picture shows some structure in the expanding shell of gas around the star, reminiscent of the much more complex Helix nebula. The nebula we see is the ejected surface of the star expanding into material left from an earlier stage in its decline, when it briefly expanded as a 'red giant'.

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

Spiral Galaxy NGC 253 in Sculptor - Spiral galaxy NGC 253 in Sculptor - NGC 253 is the brightest galaxy of the Sculptor's group, the closest galaxy group to the Local Group. It is about 10 million light years away. Image made with Siding Spring's 3.9m telescope in 1975. A mere 10 million light years away, NGC 253 is one of the nearest spiral galaxies, a member of a small group straggling across the southern constellation of Sculptor. It appears elongated because we see it almost edge - on. This galaxy is also one of the dustiest galaxies known and much of its internal detail is hidden by obscuring matter which can be seen as dark patches against the background stars. Despite the obscuration, two spiral arms and many bluish clusters of stars can be seen around the edge of the galaxy. NGC 253 is so close to us that some of the brightest stars are apparent as individuals within the spiral arms
