Researchers dig deep underground in hopes of finally observing dark matter

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.
Typical amounts of solar particles hitting the Earth’s magnetosphere can be beautiful, but too much could be catastrophic. Svein-Magne Tunli -

Solar storm knocks out farmers’ high-tech tractors – an electrical engineer explains how a larger storm could take down the power grid and the internet

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.

New era of astronomy uncovers clues about the cosmos

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.
The High Energy Stereoscopic System (HESS) was instrumental in determining the origin of cosmic rays. HESS

Supermassive black holes could be a source of mysterious 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.

An extragalactic mystery: where do high-energy cosmic rays come from?

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…
