Two astronauts aboard the ISS conducted their fourth and final spacewalk to finish a series of repairs aimed at extending the functioning of a cosmic ray detector attached to the spacecraft.
Decades ago, Armenian scientists built a high-elevation trap to catch and study cosmic rays. Physics has mostly moved on, but the station persists—a ghost observatory with a skeleton crew.
The Large Synoptic Survey Telescope, the world’s largest sky survey, will rain a monsoon of data onto the astrophysics community. Simulations prepare scientists for the approaching storm.
Enrico Fermi's notebook of December 1948 contains four pages that represent the genesis of his theory of cosmic rays, particles that can hit the Earth's atmosphere at high speeds.
Now that a Higgs-like boson has been discovered at the Large Hadron Collider, proposals to build colliders that churn out the new particle are gathering momentum.
Physicists from all over the world work the night shift to guide the Large Hadron Collider and its particle detectors from sunset to sunrise. Take a peek into two of the five CERN control rooms that are staffed 24 hours a day.
