Satellite MSG - 1 - Meteosat 8 - Artist's view of the European satellite MSG - 1 (Meteosat Second Generation) or Meteosat 8, in orbit around the Earth. Launched on August 28, 2002, it is a geostationary satellite located 35 600 km from Earth; dedicated to meteorology, it observes the Earth in visible, and in infrared. Meteosat Second Generation (MSG), is equipped with an extremely sophisticated imaging radiometer that can separate the incoming radiation into 12 (3 with the current Meteosat) different spectral bands. Each section, four of them in the visible and eight in the thermal infrared, delivers different information. They vary from visible images of weather systems during the day to cloud temperature at night; from surface temperature and water vapour to trace gas concentrations and dust particles in the atmosphere. MSG will deliver about twenty times as much information as its predecessor Meteosat, resulting in much more accurate short and medium - range forecasts

Total Eclipse of Moon 27 - 09 - 1996 - Total lunar eclipse September 27, 1996 - This montage illustrates the progression of the Moon in Earth's shadow cone. The image on the right corresponds to its complete entry into the shadow (beginning of the totalite), the central at the maximum of the totalite and the one on the left at the end of the totalite. During this eclipse, the southern pole of the Moon is passing a little above the center of the Earth's shadow cone. Thus, the southern pole of the Moon is the darkest, while the north pole is brighter. Note the color degrade for the right and left poses: from dark red towards the center of the shadow cone to white on the periphery of this cone, with an intermediate greenish orange degrade. This highlights the fact that blue is more diffuse than green by the Earth's atmosphere - hence the absence of blue on the image, because this color is lost in the Earth's atmosphere and therefore does not reach the surface of the Moon - and that green

The coldest place on Mars - Coolest place on Mars: Detail of the ice cap of the southern pole of Mars, composed mainly of carbon dioxide. This dry ice accumulates on the surface mainly in winter, the temperature of this area can sometimes drop to 130 degrees Celsius below zero. Image obtained on August 29, 2016 by the HIRISE camera on board the Mars Reconnaissance orbiter probe. HIRISE is a 50 cm telescope that observes visible and near infrared. The polar cap is made from carbon dioxide (dry ice), which does not occur naturally on the Earth. The circular pits are holes in this dry ice layer that expand by a few meters each Martian year. New dry ice is constantly being added to this landscape by freezing directly out of the carbon dioxide atmosphere or falling as snow. Freezing out the atmosphere like this limits how cold the surface can get to the frost point at -130 degrees Celsius (-200 F). Nowhere on Mars can ever get any colder this, making this coolest landscape on Earth and Mars

Martian dunes in winter - March: Winter view of Dunes - Detail on dunes in a crater located in the southern hemisphere of Mars. Clearly, areas covered with gel appear on this image obtained by the HIRISE camera of the Mars Reconnaissance probe orbiter on November 25, 2006. HIRISE is a 50 cm telescope that observes visible and near infrared. Dunes within a crater on Mars are visible in this HiRise image. This crater is located in the southern hemisphere where it was winter at the time this image was taken on November 25, 2006. This observation documents new seasonal processes occurring on dunes at this latitude, as well as other interesting phenomena. The bright tones are interpreted as carbon dioxide or water frost. This is generally concentrated on the east - facing slopes of the dunes, which are in shadow and therefore cooler. Some dark spots on the dunes may be areas that have defrosted more than surrounding terrain. Landslides and dark - toned streaks are seen on many of the west -

Satellite Sentinel - 2 - Artist's view - Artist's view of the European satellite Sentinel - 2 in orbit around the Earth. This Earth observation satellite of the European programme Copernicus observes vegetation with a resolution of 10 m to 60 m, in thirteen spectral bands ranging from visible to infrared. Sentinel - 2A was launched on June 23, 2015 and Sentinel - 2B will be launched in 2016. Sentinel - 2 carries a high - resolution multispectral optical imager to monitor changes in vegetation for Europe's environmental monitoring Copernicus programme. This mission offers key information to optimise crop yield, thus helping to improve food security. Data can be used to measure leaf area index, leaf chlorophyll and leaf water content to monitor plant growth, which is particularly important during the growing season. It will be used to generate land - cover maps, to track changes in the way land is being used and to monitor the world's forests. In addition, Sentinel-2 provides information

Arc de fog - Fogbow - Arc de fog observed in Brittany on 5 May 2006. A haze arc is formed in the way of a rainbow. The light of the Sun is reflected in the water drops of the mist, but unlike raindrops, the mist droplets are much smaller: about a millimetre for the rain versus a few centiemes for the mist. As a result, the diffraction in the mist droplets is preponderant, which results in colour refracting at random angles, between 30 and 45* around the anti-sun point (opposite the Sun). Thus, all colours blend and one sees a white arch of light, sometimes slightly bluish on the inside and red on the outside, wider than a rainbow. Fogbow seen in Brittany on May 5, 2006.

Ascetic devotees hang from a spinning wheel attached with 'Charhak tree' on the occasion of Charak Puja at Shah Dhamrai, Dhaka, Bangladesh on April 15, 2006. Charhak Puja is observed on the last days of the Bangla month of Chaitra (April) called Chatitra Sangkranti. Farmers celebrate during this festival with the devotees singing and dancing without any care. The Charak Puja is well-known for the rites of piercing the body with nails, and swirling from a high pole. A 'charhak tree' is built on the occasion, consisting of a long pole atop which a wheel is fixed. An ascetic devotee is hung from this wheel with a hook. The wheel then spins around with him at high speed. Small nails, at times red hot ones, pierce all parts of his body including his tongue. The devotee thus spinning spreads prasad (handmade sweetmeats blessed with chants) among the curious spectators and onlookers. At the root of the celebration of Charhak Puja is a belief in spirits and the cult of rebirth. Its rites sugge

Richat structure - Mauritania - satellite view - Richat structure, Mauritania, seen by satellite - Richat structure is a geological formation of volcanic origin in Mauritania. This “eye” measures 50 km in diameter. This image is a combination of an image obtained by the Landsat satellite in 1987 and a radar image obtained from the Space Shuttle (SRTM) in 2000. The relief is exaggerated by about 6 times. The picture covers an area of 68 km by 112 km. This prominent circular feature, known as the Richat Structure, in the Sahara desert of Mauritania is often noted by astronauts because it forms a conspicuous 50 - kilometer - wide (30 - mile - wide) bull's - eye on the otherwise rather featureless expanse of the desert. Initially mistaken for a possible impact crater, it is now known to be an eroded circular anticline (structural dome) of layered sedimentary rocks. Extensive sand dunes occur in this region and the interaction of bedrock topography, wind, and moving sand is evident in this

The source of the northern dune fields around the polar cap may be from the layers of dusty ice that are eroded by strong polar winds. This image was taken during the Martian northern summer, so there is no frost present on the dunes. The dunes closest to the base of the polar cap are long and parallel, indicating strong winds from the direction of the cap. As they get farther away from the polar cap, they start to form more crescent shaped dunes, called barchan dunes. Repeated observations by HiRise of dunes like these show measurable changes in some locations. This discovery adds to t

Martian dunes in Spring - March: Spring view of Dunes - Detail on sand dunes near the north pole of Mars. These dunes are covered with carbon dioxide gel during the Martian winter. In spring, dark streaks appear, sand flows caused by the degel. Image obtained by the HIRISE camera of the Mars Reconnaissance probe orbiter on April 7, 2008. HIRISE is a 50 cm telescope that observes visible and near infrared. Falling Material Kicks Up Cloud of Dust on Dunes. There is a vast region of sand dunes at high northern latitudes on Mars. In the winter, a layer of carbon dioxide ice covers the dunes, and in the spring as the sun warms the ice it evaporates. This is a very active process, and sand dislodged from the crests of the dunes cascades down, forming dark streaks. In thid image falling material has kicked up a small cloud of dust.

Charhak Puja is observed on the last days of the Bangla month of Chaitra (April) called Chatitra Sangkranti. Farmers celebrate during this festival with the devotees singing and dancing without any care. The Charak Puja is well-known for the rites of piercing the body with nails, and swirling from a high pole. A 'charhak tree' is built on the occasion, consisting of a long pole atop which a wheel is fixed. An ascetic devotee is hung from this wheel with a hook. The wheel then spins around with him at high speed. Small nails, at times red hot ones, pierce all parts of his body including his tongue. The devotee thus spinning spreads prasad (handmade sweetmeats blessed with chants) among the curious spectators and onlookers. At the root of the celebration of Charhak Puja is a belief in spirit

Malaspina Glacier can be seen just left of the center of this northeast - looking, low - oblique photograph. Located in southern Alaska on the shore of the Gulf of Alaska, Malaspina Glacier is a classic example of a piedmont glacier lying at the foot of a mountain range - - in this case, the Saint Elias Mountains (just north of the glacier). The glacier covers an area of 1500 square miles (3900 square kilometers) on the coastal plain, is almost 60 miles (97 kilometers) long, and is more than 1000 feet (300 meters) thick. The Seward Ice Field is the main source of ice for the glacier. The glacier moves in surges that push earlier - formed moraines outward into expanding concentric patterns, which you can see along the flanks of the ice mass. To the northwest of Malaspina Glacier is the curved and pointed Agassiz Glacier, which is also fed

Galaxy NGC 4650A in Centaurus - Galaxy NGC 4650A in Centaurus - The polar ring galaxy NGC 4650A is located about 130 million years away from Earth. The host galaxy is surrounded by a polar ring shaped like gas and stars. This type of galaxy is rarely observed. This image was obtained by the ANTU telescope of the VLT in 1998. This is a colour photo from the VLT that shows NGC 4650A, a member of the so - called Centaurus chain of galaxies in the southern constellation of that name. NGC 4650A is a complex system that is located at a distance of about 130 million light - years. There are two main components, a lenticular - shaped galaxy (of type S0), surrounded by a knotty extended ring - like distribution of stars, dust and gas, almost perpendicular to each other. The stars in the central, structureless region and the material (stars, gas, and dust) in the outer disk rotate in two different planes that are almost perpendicular to each other. The observed motions indicate the presence of a

Tyndall Glacier, Chile - Tyndall Glacier, Chile - The Tyndall Glacier in Torres del Paine National Park in Chile, observed from the International Space Station in November 2007. Tyndall Glacier is located in the Torres del Paine National Park in Chile. This glacier, which has a total area of 331 square kilometers and a length of 32 kilometers (based on 1996 measurements), begins in the Patagonian Andes Mountains to the west and terminates in Lago Geikie. The digital astronaut photograph taken in november 2007 records visible light in red, green, and blue wavelengths (true color). The Tyndall Glacier terminus has retreated significantly during the past 17 years. Significant ice loss was also observed earlier this year at Grey Glacier, about 30 kilometers to the north - northeast, suggesting both glaciers are responding similarly to regional changes in temperature and precipitation. A medial moraine is visible in the center of the glacier, extending along its length (top image, center le

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.

GOODS Chandra Deep Field South (CDF - S) - Image of distant galaxies obtained by the Hubble space telescope in the constellation of the furnace. Several thousand galaxies, some of which are more than 10 billion light years old, are visible in this image. Some closer galaxies also appear, including two colliding galaxies (middle left). This image is a detail (1/10th) of the complete field observed by Hubble (which contains about 25,000 galaxies) in the framework of the GOODS programme, an extensive program of study of primordial galaxies in a field of the Boreal Constellation of the Great Bear and in a field of the southern hemisphere in the constellation of the furnace. This image, taken with Hubble's Advanced Camera for Surveys, shows several thousand galaxies, many of which appear to be interacting or in the process of forming. Some of these galaxies existed when the cosmos was less than about 2 billion years old. The foreground galaxies, however, are much closer to Earth. Two of the

Desert of Libya seen by Envisat 11 - 2004 - Libyan dunes fields seen by Envisat. - The desert of Libya observed by ENVISAT satellite on November 24, 2004. The image covers an area 672 km wide and shows the two huge dune fields located south-west of Libya in the Fezzan Desert. At the top of the picture, the Ubari erg (or Awbari) appears reddish. In the middle, Murzuk erg. This Envisat image shows two huge sand dune seas in the Fezzan region of southwestern Libya, close to the border with Algeria. Most of the face of the Sahara desert stretching across Northern Africa is bare stone and pebbles rather than sand dunes, but there are exceptions - sprawling seas of multi - storey sand dunes known as 'ergs'. The Erg Ubari (also called Awbari) is the reddish sand sea towards the top of the image. A dark outcrop of Nubian sandstone separates the Erg Ubari sand from the Erg Murzuq (also called Murzuk) further south. A persistent high - pressure zone centred over Libya keeps the heart of the Saha

Jupiter's Fusion Spots seen by the Hubble Space Telescope - Sequence of images of Jupiter's atmosphere obtained on May 15, June 28 and July 8, 2008 by the Hubble Space Telescope. The Great Red Spot of Jupiter is a gigantic permanent tempete measuring nearly 25,000 km in diameter. It's been observed for over 400 years. A second red spot half smaller, appeared in 2006; visible at the bottom of the image, we see it passing on this series below the Great red spot without being disturbed by the huge cyclone. A third red spot, visible at the extreme left on the first image appeared at the beginning of 2008. We see her heading towards the Great red spot to appear on the last clash deformed and almost colorless. It seems his destiny is to be totally swallowed by the Great Red Spot. The time series shows the passage of the “” Red Spot Jr.”” in a band of clouds below (south) of the Great Red Spot (GRS). “” Red Spot Jr.”” first appeared on Jupiter in early 2006 when a previously white storm turne

Infrared view of the Andromeda galaxy - The Spitzer space telescope observed the Andromede spiral galaxy for over 18 hours on August 25, 2004, obtaining 11,000 different poses. Assembled in mosaic the result shows details never seen before. The brightest ring appears to be hole at the bottom right of the image; these are traces of the passage of a satellite galaxy. Nasa's Spitzer Space Telescope has captured stunning infrared views of the famous Andromeda galaxy to reveal insights that were only hinted at in visible light. Spitzer's 24 - micron mosaic is the sharpest image ever taken of the dust in another spiral galaxy. This is possible because Andromeda is a close neighbor to the Milky Way at a mere 2.5 million light - years away. The Spitzer multiband imaging photometer's 24 - micron detector recorded 11,000 separate snapshots to create this new comprehensive picture. Asymmetrical features are seen in the prominent ring of star formation. The ring appears to be split into two pieces

Nebula NGC 604 in the galaxy M33 - NGC 604 star forming nebula - NGC 604, is a very large star-forming region located in the galaxy M33 of the Triangle. This image is a composite of X-ray images (blue) obtained by the Chandra Space Telescope and visible (green and red) by the Hubble Space Telescope. The study of very hot gas observed in X-ray allows us to better understand the star formation activity within this nebula. NGC 604, is one of the largest known seething cauldrons of star birth in a nearby galaxy. NGC 604 is similar to familiar star - birth regions in our Milky Way galaxy, such as the Orion Nebula, but it is vastly larger in extent and contains many more recently formed stars. This monstrous star - birth region contains more than 200 brilliant blue stars within a cloud of glowing gases some 1,300 light - years across, nearly 100 times the size of the Orion Nebula. The bright stars in NGC 604 are extremely young having formed a mere 3 million years ago. The most massive stars
