Using X-ray, radio, and gamma-ray observations of a distant galaxy, a multinational team of astrophysicists has seen perhaps the first live instance of the turning on of a powerful jet from a supermassive black hole.
At the White House, President Barack Obama met the seven U.S. recipients of the 2010 Kavli Prizes to recognize and honor their seminal contributions to the three fields for which the Prizes are awarded -- astrophysics, nanoscience and neuroscience.
The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA's Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days.
The first 18 months of Fermi's Large Area Telescope (LAT) observations of the Sun have been combed through, and a research team reports that there are two distinct components of emission from the direction of the Sun.
