NASA Telescopes See Weather Patterns in Brown Dwarf
Pasadena CA (JPL) Jan 11, 2013 – Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange worlds. Brown dwarfs form out of condensing gas, as stars do, but lack the mass to fuse hydrogen atoms and produce e … more

Pasadena CA (JPL) Jan 11, 2013 – It’s not exactly icing on a cake, but it could be icing on a lake. A new paper by scientists on NASA’s Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing lakes and seas of liquid hydrocarbon on Saturn’s moon Titan. The presence of ice floes might explain some of the mixed readings Cassini has seen in the reflectivity of the surfaces of lakes on Titan. … more

Sofia Spots Recent Starburst In The Milky Way Galaxy’S Center
Edwards AFB (SPX) Jan 11, 2013 – Researchers using the Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way, and of a neighboring cluster of extremely luminous young stars embedded in dust cocoons. The images of our galaxy’s Circumnuclear Ring (CNR) and the neighboring … more

China no longer reliant on satellite image imports
Beijing (XNA) Jan 10, 2013 – China’s first high-resolution, stereo mapping satellite Ziyuan III meets international standards, ridding the country of its reliance on imports of satellite images. It was announced at a seminar reviewing the research and development of Ziyuan III held on Wednesday, one year after the satellite was launched. China used to import over 90 percent of its remote-sensing data, according … more

Testing Einstein’s E=mc2 in Outer Space
Tucson AZ (SPX) Jan 11, 2013 – UA physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world’s most iconic equation, Albert Einstein’s E=mc2, may be correct or not depending on where you are in space. With the first explosions of atomic bombs, the world became witness to one of the most important and consequential principles in physics: Energy and mass, fundamen …more

Earth-size planets common in galaxy
Berkeley CA (SPX) Jan 11, 2013 – An analysis of the first three years of data from NASA’s Kepler mission, which already has discovered thousands of potential exoplanets, contains good news for those searching for habitable worlds outside our solar system. It shows that 17 percent of all sun-like stars have planets one to two times the diameter of Earth orbiting close to their host stars, according to a team of astronomers from … more
