NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.
Photos from NASA's Mars Reconnaissance Orbiter show how the parachute that helped NASA's Curiosity rover land on Mars last summer has subsequently changed its shape on the ground. The images were obtained by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter.
Seven images taken by HiRISE between Aug. 12, 2012, and Jan. 13, 2013, show the used parachute shifting its shape at least twice in response to wind.
A laboratory experiment at NASA's Jet Propulsion Laboratory, Pasadena, Calif., simulating the atmosphere of Saturn's moon Titan suggests complex organic chemistry that could eventually lead to the building blocks of life extends lower in the atmosphere than previously thought. The results now point out another region on the moon that could brew up prebiotic materials. The paper was published in Nature Communications this week.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans.
The French-Italian Concordia station's programme of research includes glaciology, human biology and the atmosphere. ESA uses the base to prepare for future long-duration missions beyond Earth. During the winter, Concordia is under almost total darkness, with an average temperature of -51*C and a record low of -85*C. It is an ideal place to study the effects on small, multicultural teams isolated for long periods in an extreme, hostile environment. Auroras occur frequently over both the North and South polar regions, but are often difficult to see from populated areas Credits: ESA/IPEV/PNRA - E. Macdonald-Nethercott
While observing the turbulent outer atmosphere of the Sun, or corona, Solar Terrestrial Relations Observatory B (STEREO-B) gathered a novel view of our home planet and a celestial visitor in the inner solar system. Comet PanSTARRS was visible to the naked eye from Earth's northern hemisphere at the time, though STEREO might have had the better view.
