Hubble Image Showcases Star Birth In Spiral Galaxy M83![]() The spectacular new camera installed on NASA's Hubble Space Telescope during Servicing Mission 4 in May has delivered the most detailed view of star birth in the graceful, curving arms of the nearby spiral galaxy M83. Nicknamed the Southern Pinwheel, M83 is undergoing more rapid star formation than our own Milky Way galaxy, especially in its nucleus. The sharp "eye" of the Wide Field ... more Swift XMM-Newton Satellites Tune Into A Middleweight Black Hole ![]() While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. "Intermediate-mass black holes ... more Peckish bird briefly downs big atom smasher ![]() A peckish bird briefly knocked out part of the world's biggest atom smasher by causing a chain reaction with a piece of bread, the European Organisation for Nuclear Research (CERN) said Monday.

Uracil Made In The Lab![]() NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces this essential ingredient of life. Pyrimidine is a ring-shaped molecule made up of carbon and nitrogen and is the basic structure for ... more Mercury probe fly-by maps mysterious inner planet ![]() The US space probe Messenger's third and final fly-by of the planet Mercury in September revealed an almost complete view of the solar system's smallest planet, leaving only the polar regions to be surveyed, NASA said. Flying at a low altitude, the Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging) probe's cameras have now mapped some 98 percent of Mercury's surface ... more Follow Rosetta's Final Earth Boost ![]() ESA's comet chaser Rosetta will swing by Earth for the last time on 13 November to pick up energy and begin the final leg of its 10-year journey to comet 67P/Churyumov-Gerasimenko. ESA's European Space Operations Centre will host a media briefing on that day. This will be the third Earth swingby, the last of Rosetta's four planetary gravity assists. Closest approach to Earth is expected at ... more |
