PIX4617856: Orion Nebula - the trapeze - The Trapezium region in M42 - Located 1500 years - light, Orion Nebula is the closest region of formation of stars of the Sun. In the center of the picture, the Trapeze of Orion. The Trapeze is among the youngest known open clusters, it is made up of 4 massive stars that make the nebula shine. Image obtained with Siding Spring's 3.9m telescope. The central 'star' of the three groups forming the asterism of Orion's sword is in reality a nebula, and is clearly nebulous to the unaided eye. At the heart of the most luminous nebulosity shimmer a handful of stars known as the Trapezium cluster, visible in binoculars. These are the brightest members of a substantial cluster of stars, most of which are still hidden in the dusty recesses of the Orion nebula against which they are seen. The stars of the Trapezium provide much of the energy which makes the brilliant Orion Nebula visible and are at a distance of about 1500 light years. This image was made at the prime focus of the Anglo - Australian Telescope / Bridgeman Images

PIX4616373: Crater Bacolor on Mars - Bacolor Crater on planet Mars - View of the impact crater Bacolor obtained by the Mars Odyssey probe. It's an impact crater about 20 km in diameter. Bacolor Crater is a magnificent impact feature about 20 kilometers (12 miles) wide. The lines on the ejecta blanket surrounding the crater rim come from a surge of superheated gas and debris flying outward in the wake of the meteorite impact that made the crater. This view combines images taken during the period from September 2002 to October 2005 by the Thermal Emission Imaging System instrument on Nasa's Mars Odyssey orbiter. The pictured location on Mars is 33 degrees north latitude, 118.6 degrees east longitude / Bridgeman Images

PIX4616152: March: Hebes Chasma - Mars: Hebes Chasma - Hebes Chasma is a basin of almost 8000 m deep located in the northern part of Valles Marineris, the great Martian canyon. At the centre of this depression is a stratified plateau that constitutes sedimentary deposits. Image obtained by the Mars Express probe in 2005. View of Hebes Chasma obtained by the High Resolution Stereo Camera (HRSC) on ESA's Mars Express spacecraft. Hebes Chasma is an enclosed trough, almost 8000 m deep, in Valles Marineris, the Grand Canyon of Mars. A mesa - like mountain is located in the center of Hebes Chasma. It reaches 8000 meters above the graben floor and extends almost to the top of the surrounding plain. The mountain is made up by numerous stacked rock layers. The layering may consists of remnants of the older plateau, lake sediments, wind blown sediments or volcanic rock. The rock layers were exposed by erosional processes. Newest data acquired by the OMEGA spectrometer on - board Mars Express revealed hydratized (water - bearing) minerals like gypsum in some areas of Hebes Chasma. What ever kind of processes led to the formation of the Interior Layered Deposits: at least some water once existed in Hebes Chasma. Hebes Chasma is located at approximately 1* south and 282* east. The HRSC obtained image data on 16 September 2005 with a ground resolution of approximately 15 m/pixel / Bridgeman Images

PIX4616176: March: chaotic terrain between Kasei Valles and Sacra Fossae - Mars: Chaotic terrain between Kasei Valles and Sacra Fossae - Region bordering Kasei Valles and Sacra Fossae. To the north, the large impact crater is 35 km in diameter. The image covering an area of 225 km by 95 km was obtained by the Mars Express probe. Mars Express flew over the boundary between Kasei Valles and Sacra Fossae and imaged the region, acquiring spectacular views of the chaotic terrain in the area. The images are centred at 12* N/285* E and have a ground resolution of about 21 m/pixel. They cover 225 x 95 km or 21.375 sq km, an area roughly half the size of the Netherlands. The image shows an old 35 km - diameter impact crater in the north. The crater's southwestern rim is eroded strongly, mostly by flowing water. The source of the water was located in Etus Chasma, which lies about 850 km to the southwest. The crater floor and the northwestern part are remarkably flat, formed by sediments and basaltic lava flows from the Tharsis volcanic region / Bridgeman Images

It is 270 miles in diameter, almost 12 miles high, and the summit caldera is 72 miles wide. For comparison, the largest volcano on Earth is Mauna Loa. From its base on the sea floor, Mauna Loa measures only 6.3 miles high and 75 miles in diameter.

PIX4616544: Glaciers under Martian crateres - Buried glaciers on Mars - Computer reconstructed views of three Martian crateres in the Hellas region that house glaciers. The images show the crateres as they appear today with a layer of Martian soil covering the ice with water and, on the right, the glaciers updated according to radar measurements obtained by the Mars Reconnaissance Orbiter probe (MRO). These glaciers would have a thickness of 250 to 450 meters. Each image covers 20 km wide. This computer graphic image shows three craters in the eastern Hellas region of Mars containing concealed glaciers detected by radar. The images shows how the surface looks today with the ice covered with a layer of Martian soil and what the ice may look like underneath. The image was created using image data from the Context Camera on the Mars Reconnaissance Orbiter (MRO) spacecraft combined with results from the SHARAD radar sounder on MRO and HRSC digital elevation map from the Mars Express spacecraft. The color of the Martian surface and ice was estimated from MRO HiRise color images of other Martian craters and the polar ice caps. The buried ice in these craters as measured by SHARAD is ~ 250 meter thick on the upper crater and ~ 300 and 450 meters on the middle and lower levels respectively. Each image is 20 km (12.8 mi.) across and extends to 50 km (32 mi) in the distance. Recent measurements from the Mars Reconnaissance Orbiter SHARAD radar sounder have detected large amounts of water ice in such deposits over widespread areas, arguing for the flow of glacial - like structures on Mars in the relatively recent geologic past. This suggests that snow and ice accumulated on higher topography, flowed downhill and is now protected from sublimation by a layer of rock debris and dust. Furrows and ridges on the surface were caused by deforming ice / Bridgeman Images
