Argentinian astronomers have conducted radio observations of a very-high-energy gamma-ray source known as HESS J1857+026. Results of this study provide new insights into the nature of this mysterious source. The research ...
As the nation's nuclear weapons are aging (think the beginning of the Cold War), the U.S. government is turning to researchers and scientists at universities such as UC San Diego to figure out safe and reliable ways to estimate ...
