Mars: Noctis Labyrinthus - Mars: Noctis Labyrinthus - Perspective view of Noctis Labyrinthus, located in the western part of the great Martian canyon Valles Marineris. This heavily eroded canyon is here 5000 meters deep. Image obtained by the Mars Express probe on June 25, 2006. On 25 June 2006 the High - Resolution Stereo Camera (HRSC), onboard the ESA spacecraft Mars Express obtained image data with a ground resolution of approximately 16 meters per pixel. The data were acquired in the region of Noctis Labyrinthus at approximately 6.5* southern latitude and 260* eastern longitude. The region Noctis Labyrinthus, the Labyrinth of the Night”” is located directly on the western edge of Valles Marineris, the “Grand Canyon of Mars””. It is part of the complex graben system which is associated with the up - arching of Tharsis. Eye - catching is the high density of deeply incised, smaller, maze - like fractures. The scene exhibits parts of those graben structures which are incised up to 5000

Spiral galaxy M77 in the Whale - Active galaxy M77 (NGC 1068) in Cetus - M77 (NGC 1068). This active galaxy is the typical example of a Seyfert II galaxy. It has an active core and houses a massive black hole. She is the object of intense star formation in her spiral arms. NGC 1068 is around 50 million years of light from Earth. Image obtained by Siding Spring's 3.9m telescope. M77 is a Seyfert galaxy, a class of galaxy named for Karl Seyfert who first identified galaxies with emission lines superimposed on the normal radiation from their nuclei in 1943. Such galaxies are a subset of an ill - defined species generally known as 'active galaxies' whose nuclei emit radio - and X - radiation as well as visible light. The least active of the active galaxies are the Seyferts, the most active are the quasars which are mostly so distant that they can only be distinguished from stars by their spectrum. <BR>The common feature of these galaxy types is a small, very bright nucleus thought to host

Barree spiral galaxy NGC 4639 in Virgo - Barred galaxy NGC 4639 in Virgo - The barree spiral galaxy NGC 4639 is located 78 million years - light in the Virgin's galaxy cluster. The blue dots visible on this image obtained by the Hubble Space Telescope are young stars. Other stars, cepheides have also been observed in this galaxy, allowing us to measure their distance with precision. This Hubble Space Telescope image shows NGC 4639, a spiral galaxy located 78 million light - years away in the Virgo cluster of galaxies. The blue dots in the galaxy's outlying regions indicate the presence of young stars. Among them are older, bright stars called Cepheids, which are used as reliable milepost markers to obtain accurate distances to nearby galaxies.

Barree spiral galaxy NGC 4639 in Virgo - Barred galaxy NGC 4639 in Virgo - The barree spiral galaxy NGC 4639 is located 78 million years - light in the Virgin's galaxy cluster. The blue dots visible on this image obtained by the Hubble Space Telescope are young stars. Other stars, cepheides have also been observed in this galaxy, allowing us to measure their distance with precision. This Hubble Space Telescope image shows NGC 4639, a spiral galaxy located 78 million light - years away in the Virgo cluster of galaxies. The blue dots in the galaxy's outlying regions indicate the presence of young stars. Among them are older, bright stars called Cepheids, which are used as reliable milepost markers to obtain accurate distances to nearby galaxies.

The momorable outline of the Hunter proudly bestrides the celestial equator and is equally visible from both hemispheres.

Suns are born from vast clouds of dust and gas that gather in the dark places between the stars. Gravity causes these interstellar vapors to collapse inward until the pressure causes high enough temperatures at its center to fuse hydrogen, the university's basic building block, into helium - an event that also releases gamma - ray photons. These photons can take a million years to travel outward through the overlying matter until they reach the surface and escape into space as visible light.

In this NASA/ESA Hubble Space Telescope image, NGC 4874 is the brightest object, located to the right of the frame and seen as a bright star - like core surrounded by a hazy halo. A few of the other galaxies of the cluster are also visible, looking like flying saucers dancing around NGC 4874. But the really remarkable feature of this image is the point - like objects around NGC 4874, revealed on a closer look: almost all of them are clusters of stars that belong to the galaxy. Each of these globular star clusters contains many hundreds of thousands of stars. Recently, astronomers discovered that a few of these point - like objects are not star clusters but ultra -

Galaxy System Arp 274 - Galaxy triplet Arp 274 - Arp 274 (NGC 5679) is a system of three galaxies located about 400 million years ago - light in the constellation of Virgo. Image obtained by the Hubble Space Telescope. Arp 274, also known as NGC 5679, is a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation. Two of the three galaxies are forming new stars at a high rate. This is evident in the bright blue knots of star formation that are strung along the arms of the galaxy on the right and along the small galaxy on the left. The largest component is located in the middle of the three. It appears as a spiral galaxy, which may be barred.

It is one of the most extensive (165 years - light) and one of the oldest known globular clusters. Globular clusters are generally peoples of very old stars, but here the Hubble space telescope has identified some young stars, blue stragglers. The globular cluster Messier 5, shown here in this NASA/ESA Hubble Space Telescope image, is one of the oldest belonging to the Milky Way. The majority of its stars formed more than 12 billion years ago, but there are some unexpected newcomers on the scene, adding some vitality to this aging population. Stars in globular clusters form in the same stellar nursery and grow old together. The most massive stars age quickly, exhausting their fuel supply in less than a million years, and end their lives in spectacular supernovae explosions.

There is extensive and varied mythology about this beautiful collection of stars, but the most common Greek legend has Orion as a giant huntsman, and he appears in this role in Homer's Odyssey. The most persistent legend seems to be that he died from the sting of a giant scorpion, which was placed in the sky so that Orion sets as the Scorpius rises, in an eternal chase across the sky. The momorable outline of the Hunter proudly bestrides the celestial equator and is equally visible from both hemispheres. The distinctive, equally spaced line of stars of Orion's Belt are more or less on the equator and are framed by quartet of bright and colourful stars.

This scenario is widely accepted, but analyses of lunar samples have shown a major problem with this theory: the Moon should be composed mainly of Theia materials. The elements of the Moon and the Earth show remarkable similarities. Researchers explored a new collision geometry, changing the impact configuration. Their simulation also integrates a more energetic impact (called “hit and run”) that could tear more matter from Earth and make the pre-lunar debris disc dominate by terrestrial matter - The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests that the Moon formed out of the debris left over from a collision between Earth and a body of the size of Mars, a

Spiral Galaxy M66 in the Lion - Spiral galaxy M66 in Leo - M66 (NGC 3627) is a spiral galaxy located at a distance of about 35 million years - light. M66, with its neighbors M65 and NGC 3628, forms a remarkable triplet of galaxies, called the Lion Triplet or the M66 Group. Image obtained by the Hubble Space Telescope. The unusual spiral galaxy, Messier 66, is located at a distance of about 35 million light - years in the constellation of Leo. Together with Messier 65 and NGC 3628, Messier 66 is one third of the Leo Triplet, a trio of interacting spiral galaxies, part of the larger Messier 66 group. Messier 66 wins out in size over its fellow triplets - - it is about 100 000 light - years across. Messier 66 is the proud owner of exclusive asymmetric spiral arms which seem to climb above the galaxy's main disc and an apparently displaced nucleus. This asymmetry is unusual; most often, dense waves of gas, dust and newly born stars wind about the galaxy's centre in a symmetric way. Astrono

Mars: crater in Myers Valles - Mars: crater in Myers Valles - Mamers Valles is a valley about 1000 km long located in the region of Deuteronilus Mensae, north of Arabia Terra. The image obtained by the Mars Express probe on 5 August 2006 shows a crater at the end of this valley. This circular formation measures about thirty kilometres in diameter and is 1400 metres deep. There are traces of flow of material probably composed of water ice, similar to the relief left by the passage of glaciers on Earth. The darker area could be caused by local erosion or wind-driven material. The High - Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express obtained images focusing on a depression that displays a crater at the end of the long, winding valley, Mamers Valles. The data was obtained on 5 August 2006 with a ground resolution of approximately 14 m/per pixel. The image is centred at approximately 39* north and 17* east on the planet.

This image gives the first clear view of the faint boundary of the Crab Nebula's X - ray - emitting pulsar wind nebula. The nebula is powered by a rapidly rotating, highly magnetized neutron star, or pulsar (white dot near the center). The combination of rapid rotating and strong magnetic field generates an intense electromagnetic field that creates jets of matter and anti - matter moving away from the north and south poles of the pulsar, and an intense wind flowing out in the equatorial direction.

Galaxy UGC 10214 in the Dragon - Galaxy UGC 10214 in Draco - The galaxy UGC 10214 is about 420 million years away - light from Earth. The shape of this galaxy is due to a collision with another galaxy, the small galaxy, blue, visible in the upper left corner of the image. Powerful gravitational forces are responsible for the formation of the tail, consisting of stars of dust and gas, which stretches over nearly 28,000 light years and is composed of recently formed and extremely bright blue stars. In the background, more than 6000 galaxies are visible, some more than 12 billion years apart - light. Image obtained by the Hubble Space Telescope in April 2002. This picture of the galaxy UGC 10214 was taken by the Advanced Camera for Surveys (ACS), which was installed aboard Nasa's Hubble Space Telescope in March during Servicing Mission 3B. Its distorted shape was caused by a small interloper, a very blue, compact galaxy visible in the upper left corner of the more massive Tadpole. The Tad

Barree spiral galaxy UGC 12158 - Galaxy UGC 12158 - The galaxy UGC 12158, is about 400 million light years away from Earth in the constellation Pegase. In this image obtained by the Hubble space telescope, a blue star is visible near the center of the galaxy (lower left), it is a supernova, SN 2004ef. The galaxy captured in this image, called UGC 12158, certainly isn't camera - shy: this spiral stunner is posing face - on to the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys, revealing its structure in fine detail. UGC 12158 is an excellent example of a barred spiral galaxy in the Hubble sequence - - a scheme used to categorise galaxies based on their shapes. Barred spirals, as the name suggest, feature spectacular swirling arms of stars that emanate from a bar - shaped centre. Such bar structures are common, being found in about two thirds of spiral galaxies, and are thought to act as funnels, guiding gas to their galactic centres where it accumulates to form newborn st
