On September 10, physicists and physics enthusiasts around the world watched expectantly as CERN attempted to circulate particle beams in the Large Hadron Collider for the first time.
US particle physics is pushing forward on three frontiers. Each has a unique approach to making discoveries, and all three are essential to answering key questions about the laws of nature and the cosmos.
Do the most energetic particles in the universe come from supermassive black holes? New results from the Pierre Auger Observatory make that case.
Fermi National Accelerator Laboratory in Batavia, Illinois has a challenge: how will it maintain its central role as a place where particle accelerators produce groundbreaking discoveries in physics?
In less than three years, scientists will start up the world's largest scientific instrument: The Large Hadron Collider. US scientists have built key components for the machine and its experiments, paving the way for their participation in a decade of discoveries.
