The object was discovered using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia, South-West Africa. One theory is that it's the remnant from a supernova that exploded 10,000 years ago; this has enough energy to accelerate gamma rays so strongly. The object is also very near the supermassive black hole at the centre of the Milky Way, so this radiation could be somehow associated with it. http://www.universetoday.com/am/publish/mystery_heart_milky_way.html <a href="http://www.universetoday.com/am/publish/mystery_heart_milky_way.html";>AOL Link</a> GLACIERS SPEED UP WHEN ICE BREAKS AWAY Sep 22, 2004 - When the Larsen B ice shelf broke away from the coast of Antarctica two years ago, nearby glaciers surged, flowing eight times faster. This is according to a new study by NASA-funded researchers who used several Earth observing satellites to track the movements of Antarctic glaciers. It appears that the ice shelves hold glaciers back, like a dam. Once the shelf breaks up, the glacier is free to flow quickly. These glaciers aren't that large, but this research gives scientists an understanding of what will happen as rising temperatures continue breaking up Antarctica's ice shelves. http://www.universetoday.com/am/publish/antarctic_glaciers_speed_up.html <a href="http://www.universetoday.com/am/publish/antarctic_glaciers_speed_up.html";>AOL Link</a> MARS ROVERS GET A MISSION EXTENSION Sep 22, 2004 - NASA has approved a six month extension for the Mars Exploration Rovers, giving them more time to continue exploring the surface of Mars for evidence of past water. Both Spirit and Opportunity have completed their original three-month mission, and an additional five-month extension. Even though the rovers are well past their expected operational life, neither one is showing much sign of wear, so NASA scientists plan to keep them running. The rovers took a 12-day break earlier this month as Mars passed behind the Sun, disrupting all communication to and from the Red Planet. http://www.universetoday.com/am/publish/mars_rovers_mission_extension.html <a href="http://www.universetoday.com/am/publish/mars_rovers_mission_extension.html";>AOL Link</a> Additional headlines from Universe Today http://www.universetoday.com/am/exec/search.cgi?start=5&perpage=8&template=index/default.html <a href="http://www.universetoday.com/am/exec/search.cgi?start=4&perpage=8&template=index/default.html";>AOL Link</a> All contents copyright (c) 2004 Universe Today ----------------------------------------------------- -- To unsubscribe from: Universe Today - Daily Edition (Text), just follow this link: http://www.universetoday.com/mojo/mojo.cgi?f=u&l=ut%2dtext&[EMAIL PROTECTED]&p=4996766 Click this link, or copy and paste the address into your browser.
