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.
The High Energy Stereoscopic System (HESS) was instrumental in determining the origin of cosmic rays.
A new study suggests that mysterious high energy cosmic rays might originate from the supermassive black hole at the centre of our galaxy.
The moon can be used to help in the hunt for high energy particles.
When looking for evidence of some of the universe’s mysterious high energy particles, why not enlist the help of our nearest neighbour: the moon.
Ice cold physics: hunting for neutrinos in Antarctica.

Astronauts living on the ISS get to experience the wonders of the universe’s natural phenomena like no one else.
Knowing where cosmic rays don’t come from brings scientists another step closer to determining their origin.
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…
An Antarctic observatory studying gamma ray bursts (GRBs) has failed to detect neutrino emissions, possibly ruling out the…
