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.
Scientists from Cornell University and Brookhaven National Laboratory have successfully demonstrated the world’s first capture and reuse of energy in a multi-turn particle accelerator.
Filled with rare, low-radioactivity material, the DarkSide-50 experiment will have some of the lowest background rates of any dark-matter detector. That should help it detect highly sought-after dark-matter candidates called weakly interacting massive particles, or WIMPs.
Researchers at Berkeley Lab have measured the quality of beam produced by a plasma accelerator, revealing that this novel type of accelerator may be better suited for light-source science than previously thought.
If you could detect a bowling ball’s gravitational waves, you would know when someone threw the ball—even if you were standing outside the bowling alley.
A growing suite of computational instruments is helping scientists determine how fast local concentrations of dark matter move, which in turn could help them cut in on the dance of dark matter particles.
