In 2002, a satellite called INTEGRAL was launched by the European Space Agency with an instrument on board to detect and measure gamma rays from space. Four years later, it yielded some intriguing data: An unusually high ... | |
First stars might have been powered by dark matter February 12, 2008 | User rating: 4.2 / 5 after 62 vote(s)
| User comments: 18
For a long time, scientists have assumed that the very first stars were powered by fusion, in processes similar to what goes on in present day stars. But a new theory is emerging to challenge that view. “The first stars were ... | |
 Physicists Demonstrate How Information Can Escape From Black Holes May 14, 2008 | User rating: 4.4 / 5 after 98 vote(s)
| User comments: 17
Physicists at Penn State have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general ... | |
V-shaped solar cells could lead to better efficiency December 19, 2007 | User rating: 4.6 / 5 after 100 vote(s)
