To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.
Every few centuries the sun blasts the Earth with a huge amount of high-energy particles. If it were to happen today, it would wreak havoc on technology.
Astronomers are now able to detect a host of signals streaming through the universe. This newfound ability is like gaining new senses and it’s opening the door to understanding the cosmos.
Scientists say they now know that high energy cosmic ray particles that bombard Earth are coming from outside our galaxy. But the actual source still remains a mystery.
The true radiation risk from commercial flying has nothing to do with security scans. A radiation expert explains how much cancer risk the most frequent of flyers take on when they take to the skies.
A cubic kilometer of clear, stable ice could help physicists answer big questions about cosmic rays and neutrinos. Hardy scientists collect data via a unique telescope at the frozen bottom of the world.
It’s been the defining question of high-energy astrophysics for the past century: where do cosmic rays come from? New findings from the IceCube Neutrino Observatory at the South Pole have brought us closer…
