International Space Station: Astronaut Exit - The International Space Station: EVA Astronaut: Astronaut Rick (Richard) Linnehan during the third extravehicular Exit of the STS-123 mission, March 18, 2008. Anchored to a Canadarm2 mobile foot restraint, astronaut Rick Linnehan, STS-123 mission specialist, participates in the mission's third scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the 6-hour, 53-minute spacewalk, Linnehan and astronaut Robert L. Behnken (out of frame), mission specialist, installed a spare-parts platform and tool-handling assembly for Dextre, also known as the Special Purpose Dextrous Manipulator (SPDM). Among other tasks, they also checked out and calibrated DEXT's end effector and attached critical spare parts to an external stowage platform. The new robotic system is scheduled to be activated on a power and data grapple fixture located on the Destiny laboratory on flight day

CRYOSAT-2 satellite - The European Cryosat-2 satellite is being tested at the Space Test Centre at IABG (Industrieanlagen - Betriebsgesellschaft mbH) in Ottobrunn, Germany, in September 2009. This satellite is intended to study polar ice. CryoSat - 2 undergoing testing at the Space Test Centre at IABG (Industrieanlagen - Betriebsgesellschaft mbH) in Ottobrunn, Germany in September 2009. CryoSat will be the third of ESA's Earth Explorer satellites in orbit. The 700 kg CryoSat spacecraft whose name comes from the Greek kryos meaning cold or ice carries the first all - weather microwave radar altimeter. The instrument has been optimised for determining changes in the thickness of both floating sea ice, which can be up to several meters, and polar land ice sheets, which in Antarctica can be close to 5 km thick. The mission will deliver data on the rate of change of the ice thickness accurate to within one centimetre

Galaxies cluster Abell 2744 - This image of the galaxy cluster Abell 2744 located in the constellation of the Sculptor, combines images obtained in visible form by the Hubble Space Telescope (HST) and the Very Large Telescope (VLT). This image of galaxy cluster Abell 2744 combines data from the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys, with an image taken with the European Southern Observatory's Very Large Telescope (VLT). Hubble provides the central, most detailed part of the image, while the VLT, which has a wider field of view, provides the outer parts of the image.

Planetary nebula NGC 6543 in the Dragon - Planetary nebula NGC 6543 in Draco - Composite view of the planetary nebula NGC 6543 in the Dragon obtained by the Hubble space telescope and X-ray (blue) by the Chandra satellite. NGC 6543 is located about 3000 years of light from Earth. This composite of data from Nasa's Chandra X - ray Observatory and Hubble Space Telescope is a new look for NGC 6543, better known as the Cat's Eye nebula. This famous object is a so - called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes

Wind emis by a Black Hole Supermassif - Artist view - Wind from Supermassive Black hole - Artist view - Wind artist's view emitted by a supermassive black hole in the center of a galaxy. These extremely strong winds could hinder star formation within the galaxy. Supermassive black holes at the cores of galaxies blast radiation and ultra-fast winds outward, as illustrated in this artist's conception. New data from NASA's Nuclear Spectroscopic Telescope Array (NuStar) and the European Space Agency's (ESA's) XMM-Newton telescopes show that these winds, which contain gases of highly ionized atoms, blow in a nearly spherical fashion, emanating in every direction, as shown in the artwork. The findings rule out the possibility that the winds blow in narrow beams. With the shape and extent of the winds known, the researchers were able to determine the winds' strength. The high-speed winds are powerful enough to shut down star formation throughout a galaxy

Open cluster of Pleiades - Open cluster of Pleiades - The north is at top. The Pleiades star cluster, also known as the Seven Sisters and Messier 45, is one of the brightest and famous star clusters visible in the northern hemisphere. It consists of about 500 bright, hot, young stars that were all born at the same time between 75 and 150 million years ago within a large cloud of dust and gas. The cluster contains many stars, of which only a handful are commonly visible to the naked eye. The blue haze that accompanies them is due to very fine dust which still remains and preferentially reflects the blue light from the stars. This star cluster lies some 440 light years away from the Earth, in the constellation of Taurus. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory

Titan, Saturn satellite seen by Cassini: Visible and infrared composite image of Titan taken by the Cassini probe on September 12, 2013. View of methane and ethane lakes. - This false-color mosaic, made from infrared data collected by Nasa's Cassini spacecraft, reveals the differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn's largest moon. Titan is the only other place in the solar system that we know has stable liquid on its surface, though its lakes are made of liquid ethane and methane rather than liquid water. While there is one large lake and a few smaller ones near Titan's south pole, almost all of Titan's lakes appear near the moon's north pole - Scientists mapped near-infrared colors onto the visible color spectrum. Red in this image was assigned a wavelength of 5 microns (10 times longer than visible light), green 2.0 microns (four times longer than visible light), and blue 1.3 microns (2.6 times longer than visible light) - The orange

Black Holes in 3C75 - Black Holes in 3C75 - Composite X-ray image (blue) and radio (pink) of the active galaxy 3C 75. At the center of this very hot gas mass, two supermassive black holes separated by 25,000 years - light form a binary system of black holes (the two bright points). This composite X - ray/radio image of Abell 400 shows radio jets (pink), immersed in a vast cloud of multimillion degree X - ray emitting gas (blue) that pervades the cluster. The jets emanate from the vicinity of two supermassive black holes (bright spots in the image) in the galaxy. Chandra and radio data confirm that the unusual structure is due to the merger of two large galaxies, whose supermassive black holes are bound together by their mutual gravity. The swept - back appearance of the radio jets is produced by the rapid motion of the galaxy through the hot gas of the cluster, in much the same way that a motorcyclist's scarf is swept back while speeding down the road

The first of NGC 7098's double features is a duo of distinct ring-like structures that loop around the galaxy's hazy heart. This central region hosts a second double feature: a double bar. NGC 7098 has also developed features known as ansae, visible as small, bright streaks at each end of the central region. Ansae are visible areas of overdensity - they commonly take looping, linear, or circular shapes, and can be found at the extremities of planetary ring systems, in nebulous clouds, and, as is the case with NGC 7098, in parts of galaxies that are packed to the bri

Barree spiral galaxy NGC 7098 - Barred spiral galaxy NGC 7098: The barree spiral galaxy NGC 7098 is located about 95 million light years away from Earth in the southern constellation of the octant. Image obtained by the Very Large Telescope (VLT). Approximately 95 million light-years away, in the southern constellation of Octans (The Octant), lies NGC 7098 - an intriguing spiral galaxy with numerous sets of double features.

Star formation in the nebula NGC 2467 - Star - forming region NGC 2467 - Star formation in the nebula NGC 2467, located approximately 17,000 years ago - light from Earth in the southern constellation of Stern. Image obtained by the Hubble Space Telescope in 2004. A colourful star - forming region is featured in this stunning new NASA/ESA Hubble Space Telescope image of NGC 2467. Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas - - mostly hydrogen - - that serves as an incubator for new stars. It is located about 17,000 light years away in the southern constellation of Puppis. This picture was created from images taken with the Wide Field Channel of the Advanced Camera for Surveys through three different filters (F550M, F6

Remains of supernova G292.0+1.8 in X - G292.0+1.8 supernova remnant - X-ray view of the rest of supernova G292.0+1.8 located about 20,000 years - light in the constellation Centaurus. In the center of the image, the massive star that exploded gave way to a pulsar. The different colours represent different chemical elements (oxygen, magnesium...). The image was composed with a black and white image obtained in visible light. The aftermath of the death of a massive star is shown in detail in this composite image of G292.0+1.8. In color is the Chandra X - ray Observatory image and in white is optical data from the Digitized Sky Survey. Near the center of G292.0+1.8 is the so - called pulsar wind nebula, most easily seen in high energy X - rays. This is the magnetized bubble of high - energy particles that surrounds the “” pulsar””, a rapidly rotating neutron star that remained behind the original, massive star exploded.

Galaxy cluster Abell 1689 - Gravitational lenses in Abell 1689 galaxy cluster - Galaxy cluster Abell 1689 is about 2.2 billion years ago - light in the constellation of the Virgin. This image shows, by a gravitational mirage effect, the deformed image of many galaxies located behind the cluster. Near infrared and visible image obtained by the Hubble space telescope. 34 hours of installation. This new Hubble image shows galaxy cluster Abell 1689. It combines both visible and infrared data from Hubble's Advanced Camera for Surveys (ACS) with a combined exposure time of over 34 hours (image on left over 13 hours, image on right over 20 hours) to reveal this patch of sky in greater and striking detail than in previous observations. This image is peppered with glowing golden clumps, bright stars, and distant, ethereal spiral galaxies. Material from some of these galaxies is being stripped away, giving the impression that the galaxy is dripping, or bleeding, into the surrounding space. Also

GAIA satellite - Illustration - View of the European satellite GAIA against a milky lane background. The objective of the Gaia mission is to carry out the largest possible census of the stars of our Galaxy and to create a 3D map of a very precise 3D map. The satellite will determine the position, color and proper movement of a billion stars. Gaia was launched since Kourou on December 19, 2013. Artist's print of Gaia. Gaia is an ambitious mission to chart a three - dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. Combined with astrophysical information for each star, provided by on - board multi - colour photometry, these d

Glacier Malaspina, Alaska - The Malaspina Glacier in Alaska - Le Glacier Malaspina, Alaska, from perspective. This image is the result of joint observations made by the Landsat-7 satellite in August 2000 in visible and infrared, combined with elevation radar data obtained by the SRTM (Shuttle Radar Topography Mission) in February 2000. This glacier extends over 3000 km2. Natural colours have been applied to this image: light blue, ice, white, snow, green vegetation, grey rock and blue for the ocean. Malaspina Glacier in southeastern Alaska is considered the classic example of a piedmont glacier. Piedmont glaciers occur where valley glaciers exit a mountain range onto broad lowlands, are no longer laterally confined, and spread to become wide lobes. Malaspina Glacier is actually a compound glacier, formed by the merger of several valley glaciers, the most prominent of which seen here are Agassiz Glacier (left) and Seward Glacier (right). In total, Malaspina Glacier is up to 65 kilometer
