Testing For Dark Matter
University of Chicago cosmologist Rocky Kolb describes the history of dark matter: how it was overlooked by most physicists for decades together with current hypotheses of what it might be and experiments to determine which one is valid.

NASA’s Fermi Links Ghost Particle to Galaxy
Nearly 10 billion years ago, the black hole at the center of a distant galaxy produced a powerful outburst, and light from this blast began arriving at Earth in 2012. Astronomers using data from NASA's Fermi Gamma-ray Space Telescope and...

NASA's Fermi Links Cosmic Neutrino to Monster Black Hole
For the first time ever, scientists using NASA's Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at nearl-light speed before being detected...

Nuclear Reactions, Radioactivity, Fission and Fusion
Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...
