Spiral galaxy M33 in the Triangle - Spiral galaxy M33 in Triangulum - M33, (NGC 598), the galaxy of the Triangle, is located about 2 million years ago - light from Earth. It belongs to the local group, just like our galaxy or Andromede galaxy. In red, star-forming regions appear. Also known as M33 or NGC 598, the Triangulum Galaxy is part of the Local Group of galaxies, which includes the Andromeda Galaxy (M31) and our galaxy, the Milky Way. M33 is over thirty thousand light - years across, and more than two million light - years away. The optical data in this image show the many stars within the galaxy as well as reddish star forming regions that are filled with hot hydrogen gas. Hot, massive stars which recently formed in M33 give the galaxy its bluish color. The reddish areas are nebulae in the galaxy in which stars are rapidly forming

Globular cluster M72 in Aquarius - Globular cluster M72 in Aquarius - M72 (NGC 6981) is a cluster of stars located about 50,000 years from Earth. Image obtained by the Hubble Space Telescope. This rich collection of scattered stars, known as Messier 72, is actually a globular cluster, an ancient spherical collection of old stars packed much closer together at its centre. As well as huge numbers of stars in the cluster itself the picture also captures the images of many much more distant galaxies seen between and around the cluster stars. English astronomer Pierre Megchain discovered this rich cluster in August of 1780, but we take Messier 72's most common name from Mechain's colleague Charles Messier, who recorded it as the 72nd entry in his famous catalog of comet - like objects just two months later. This globular cluster lies in the constellation of Aquarius (the Water Bearer) about 50 000 light - years from Earth. This image was taken with the Wide Field Channel of the Advanced Cam

Elliptical galaxy NGC 1275 in Persee - Elliptical galaxy NGC 1275 in Perseus - This image obtained by the Hubble space telescope in 1995 shows a system of two colliding galaxies; in the foreground, a spiral galaxy seen almost from the edge, with many stars forming in the background, a giant, very bright elliptical galaxy, special because it has a spiral structure in its center. Its core probably houses a black hole. NGC 1275 is located about 230 million years ago - light; it belongs to the large cluster of galaxies of Persee. These images, taken with Hubble's Wide Field Planetary Camera 2 (WFPC2), show traces of spiral structure accompanied by dramatic dust lanes and bright blue regions that mark areas of active star formation. Detailed observations of NGC 1275 indicate that the dusty material belongs to a spiral system seen nearly edge - on in the foreground. The second galaxy, lying beyond the first, is actually a giant elliptical with peculiar faint spiral structure in its nucleus.

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 12 million light years away. NGC 253 is a spiral galaxy (about 12 million light years away), a member of a small group straggling across the southern constellation of Sculptor. It appears elongated because we see it almost edge - on. NGC 253 is a prototypical starburst galaxy.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.

It is about 12 million light years away. Image made with the 1.5m Danish telescope of La Silla in Chile in 2009. NGC 253 is a spiral galaxy (about 12 million light years away), a member of a small group straggling across the southern constellation of Sculptor. It appears elongated because we see it almost edge - on. NGC 253 is a prototypical starburst galaxy.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. Image taken with the ESO/Danish 1.5m telescope at La Si

Irregular galaxy NGC 6822 in Sagittarius - Irregular galaxy NGC 6822 in Sagittarius - The galaxy NGC 6822 is located about 1.8 million years ago - light from Earth. She belongs to our local group. Image obtained with Siding Spring's 3.9m telescope. NGC 6822 is one of the nearest galaxies to the milky Way and is thus a member of a small cluster known as the Local Group to which our Galaxy belongs. It is close enough to be resolved into individual stars, though because of its distance (about 1.8 million light years) only the brightest are seen, even with a telescope as powerful as the AAT. The galaxy seems to be without symmetry and is classified as an irregular. At one end of a prominent bar a few clouds of glowing gas can be seen; at the other, bright bluish stars are scattered out into what appears to be the first signs of a straggling spiral arm

Spiral galaxy M74 in Pisces - Spiral galaxy M74 in Pisces - Image of the spiral galaxy M74 (NGC 628). This galaxy is about 80,000 light years and is 30 million light years apart. Viewed face on, as it appeared about 30 million years ago, M74 is considered to be one of the most photogenic spiral galaxies in the sky. The galaxy is rich in young bright blue stars and glowing red regions of dust and molecular hydrogen where new stars are being created. M74, however, is quite camera shy - it has a low surface brightness that makes it challenging for both visual observers and astrophotographers to see it's entire form. The Chandra X - Ray observatory, discovered M74 to be the home of a super massive black hole, tucked away in one of it's outer arms. This black hole is one of the largest ever discovered and has the mass of over 10,000 suns

This image was obtained by Siding Spring's 3.9m telescope. This is one of many peculiar galaxies that populate the large southern constellation of Centaurus. This remarkable spiral galaxy seen almost edge - on, and the spiral structure is chaotic and difficult to discern. In part this is because the galaxy is itself extremely dusty, and it is seen through dust in the Milky Way. These effects together account for its yellowish hue, though patches of bluish stars can be seen. The dust in NGC 4945 absorbs most of the visible light, especially the blue light from the numerous bright stars known present within the galaxy. This energy is re - radiated at infrared wavelengths, which penetrate dust more readily, which is why the galaxy is found to be unusually bright in the infrared

Cepheides in the galaxy M81 - Cepheids in the galaxy M81 - Cepheides are very bright variable stars that serve as cosmic beacons to measure distance from nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years. Image obtained in 1993. Astronomers have discovered variable stars in the spiral galaxy M81, and measured the distance of the galaxy to be 11 million light - years (3.4 megaparsecs). They quote a 10% uncertainty in this result (plus or minus approximately one million light - years).

It is the dominant member of a small group of about half a dozen galaxies, the M74 galaxy group. In its entirety, it is estimated that M74 is home to about 100 billion stars, making it slightly smaller than our Milky Way. Its perfectly symmetrical spiral arms emanate from the central nucleus and are dotted with clusters of young blue stars and glowing pink regions of ionized hydrogen (hydrogen atoms that have lost their electrons). These regions of star formation show an excess of light at ultraviolet wavelengths. Tracing along the spiral arms are winding dust lanes that also begin very near the galaxy's nucleus and follow along the length of the spiral arms

Globular cluster NGC 6401 in Ophiuchus - Globular cluster NGC 6401 in Ophiuchus - The NASA/ESA Hubble Space Telescope has used its powerful optics to separate the globular cluster NGC 6401 into its constituent stars. What was once only visible as a ghostly mist in the eyepieces of astronomical instruments has been transformed into a stunning stellar landscape. NGC 6401 can be found within the constellation of Ophiuchus (The Serpent Bearer). The globular cluster itself is relatively faint, so a telescope and some observational experience are required to see it. Globular clusters are very rich, and generally spherical, collections of stars, hence the name. They orbit the cores of galaxies, with the force of gravity also keeping the stars bound as a group. There are around 160 globular clusters associated with our Milky Way, of which NGC 6401 is one. These objects are very old, containing some of the most ancient stars known. However, there are many mysteries surrounding them, with the or

NGC 1961 (Arp 184) is a problematic galaxy. Its highly disturbed and asymmetric spiral arms would normally indicate an interaction or merger with another galaxy. However, no culprit is found to be the source of NGC 1961's angst. Given the apparent size and brightness of this galaxy - it must be one of the largest galaxies in our “” local”” universe. The shape of the galaxy may be due to its interaction with the gas in the cluster.

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

Remains of the Supernova of Vails - The Vela supernova remnant: Nearly 12,000 years ago, a massive star exploded in the constellation of Vails. The star reaches the end of life and expels its material to become a small star only a few kilometres in diameter. This stellar corpse is a neutron star, the pulsar of Voiles, barely visible in the image. The gas shell that surrounds it today extends over more than 100 light years.

Remains of the Supernova of Vails - The Vela supernova remnant: Nearly 12,000 years ago, a massive star exploded in the constellation of Vails. The star reaches the end of life and expels its material to become a small star only a few kilometres in diameter. This stellar corpse is a neutron star, the pulsar of Voiles, barely visible in the image. The gas shell that surrounds it today extends over more than 100 light years.

Constellation of Big Bear - Constellation of Ursa Major - The constellation of Big Bear with the constellations of Hunting Dogs and Little Lion. Ursa Major is the third largest constellation in the sky but is not seen by skywatchers in the far southern hemisphere. However, it is the most recognisable of all constellations for those who can see it, mainly because of the asterism formed by the seven brightest stars. This is known as the Big Dipper in the USA, the Plough in Britain, various kinds of carts in Europe and a range of other objects in other cultures. Not surprisingly the constellation as a whole has a rich mythology associated with it, with many peoples projecting their stories among these beautiful stars. Greatly abbreviated, one ancient Greek version has Zeus romancing Callisto. His wife Hera changed Callisto into a bear out of jealousy. Hera's son Arcus found Callisto (the bear) by chance in the forest and was about to kill her, so to save her, Zeus turned Arcus into a smal

In November 1994, light emitting from a supernova type Ia, SN 1994ae, part of this galaxy, reached Earth. In this image taken by the Hubble space telescope in May 2003, this supernova is no longer detectable. On the other hand, the telescope was able to observe in this galaxy cepheides, variable stars used to accurately measure distances in the universe and calculate the rate of expansion of the universe. Many galaxies are visible in the background. The majestic dusty spiral, NGC 3370, looms in the foreground in this NASA Hubble Space Telescope image. Recent observations taken with the Advanced Camera for Surveys show intricate spiral arm structure spotted with hot areas of new star formation.

The Large Magellanic Cloud - The Large Magellanic Cloud - The Great Magellan Cloud galaxy is located about 160,000 light years away from Earth in the southern constellation of Dorado. Visible with the naked eye in the southern hemishere it is one of the closest galaxies to us. It contains large star-forming zones such as the Tarantula Nebula (30 Sea bream, visible to the left), the most active star-forming regions of the local group. Image obtained by the 1.2m UK Schmidt telescope from Siding Spring, Australia. The Large Magellanic Cloud (LMC) is the nearest galaxy to the Milky Way but less than one tenth as massive; even so it contains the equivalent of over ten billion solar masses of material in the form of stars, gas and dust. The LMC is at a distance of 160,000 light years and is visible to the unaided eye from southern latitudes, rather like a detached piece of the Milky Way.

A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This Giant Galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. Centaurus A is a most unusual galaxy. The circular, uniformly bright portion is composed of several thousand million stars, most of them old and yellowish.

Image obtained by the Hubble Space Telescope (HST) - This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud (LMC). This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star form

The galaxy is rich in young bright blue stars and glowing red regions of dust and molecular hydrogen where new stars are being created. M74, however, is quite camera shy - it has a low surface brightness that makes it challenging for both visual observers and astrophotographers to see it's entire form.

Barree spiral galaxy NGC 4394 in Berenice's Hair - Barred spiral galaxy NGC 4394 in Coma Berenices: NGC 4394 is a barree spiral galaxy located in the Virgin's cluster about 55 million light years from Earth. Image obtained by the Hubble Space Telescope (HST) - Discovered in 1784 by the German-British astronomer William Herschel, NGC 4394 is a barred spiral galaxy situated about 55 million light-years from Earth. The galaxy lies in the constellation of Coma Berenices (Berenice's Hair), and is considered to be a member of the Virgo Cluster. NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy's central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. At the centre of NGC 4394 lies a region of ionised gas known as a LINER. Liners are active regions that display a characteristic set of emission lines in their spectra- mostl

Barree spiral galaxy NGC 3259 in the Great Bear - Barred spiral galaxy NGC 3259 in Ursa Major - The barree spiral galaxy NGC 3259 is located about 110 million years away - light from Earth. This galaxy houses a black hole in its heart as well as large zones of star formation in its arms. This image was taken by the Hubble Space Telescope (HST). This classic shot of a galaxy in the constellation of Ursa Major was taken by the NASA/ESA Hubble Space Telescope. NGC 3259 is a bright barred spiral galaxy located approximately 110 million light - years from Earth. Being a fully - formed active galaxy, its bright central bulge hosts a supermassive black hole, whose huge appetite for matter explains the high luminosity of the galaxy's core: as it devours its surroundings, the black hole emits intense radiation across the whole electromagnetic spectrum, including in visible light. The beautiful spiral arms of the galaxy are not left out either as they contain dark lanes of dust and gas, ideal sp

Spiral Galaxy NGC 4452 - Galaxy Spiral NGC 4452 - NGC 4452 is located about 60 million light years away from Earth in the galaxy cluster of Our Lady. Seen from the Earth, this spiral galaxy is presented by the slice, leaving only the thickness of its disc visible. Image obtained by the Hubble Space Telescope. The NASA/ESA Hubble Space Telescope has imaged a striking galaxy called NGC 4452, which appears to lie exactly edge - on as seen from Earth. The bright nucleus can be seen at the centre, along with the very thin disc that looks like a straight line from our unusual viewing position. To complete the picture, a hazy halo of stars on the periphery of the galaxy makes it seem to glow. NGC 4452 was first seen by William Herschel in 1784 with his 47 cm telescope in England. He described the object as a bright nebula, small and very much elongated. The new Hubble image shows just how elongated this unusual object really is. NGC 4452 is part of the Virgo Cluster, so - called because many

Barree spiral galaxy NGC 1559 and supernova - Barred spiral galaxy NGC 1559 with a supernova - The galaxy NGC 1559 is a galaxy of Seyfert located about 50 million years ago - light in the constellation Reticule. In this image obtained in 2005 by the Kueyen European telescope of the VLT in Chile, a bright star is visible just above the galaxy, a supernova of type Ia named SN 2005df. On the night of August 4, 2005, an amateur astronomer and supernovae discoverer Reverend Robert Evans discovered a supernova just North of this galaxy. This supernova is classified as a somewhat unusual type Ia supernova, caught probably 10 days before it reached its maximum brightness. Such a supernova is thought to be the result of the explosion of a small and dense star - a white dwarf - inside a binary system. As its companion was continuously spilling matter onto the white dwarf, the white dwarf reached a critical mass, leading to a fatal instability. NGC 1559 is a SBc (s) - type spiral galaxy located a
