Last month astrophysicists at Stanford's Kavli Institute for Particle Astrophysics and Cosmology presented their latest results from NASA's Fermi Gamma-Ray Space Telescope's observations of supernova remnants. And they think those results add to a growing body of evidence that cosmic rays -- highly...
Researchers have narrowed down the size requirements for dark matter -- the elusive stuff that pervade the universe, lending mass but emitting no detectable radiation.
Our Universe, and everything in it, was created by the Big Bang... or was it?
The space telescope has spotted, for the first time, antimatter generated during thunderstorms on Earth.
How are gamma ray bursts generated? Is the exotic "magnetar" behind them? Or could the most powerful explosions in the Universe be caused by newborn black holes?
New research points to a dark matter signature in the sky, but it might be an effect of the mysterious gamma ray lobes that stick out of the black hole in the center of our galaxy.
How can an infrared telescope possibly track down some of the most powerful gamma-ray sources in the cosmos?
