Earth's magnetic shield weakened around 41,000 years ago, resulting in increased bombardment of our atmosphere by energetic charged particles called cosmic rays. Skip to main content.

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

41 000 years ago, the Earth's magnetic field faded and practically disappeared, leaving our planet unprotected from the bombardment of cosmic rays. Evidence for this event has been found in ocean ...

MUMBAI, Nov. 3 (UPI) --The world's largest, most sensitive cosmic-ray detector has identified a potential crack in Earth's magnetic field.The weakness was revealed by a burst of galactic cosmic ...

Are cosmic rays dangerous? Earth's magnetic field and atmosphere shields the planet from 99.9 percent of the radiation from space. However, ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

This is because cosmic rays are charged particles, and so Earth's magnetic field guides them towards the Earth's magnetic poles. (Millikan and Compton would go on to have a series of debates on the ...

The cracking of the magnetic shield under this gigantic attack led to a two-hour long cosmic ray shower on Earth. GRAPES-3 is a muon telescope located at Cosmic Ray Laboratory in Ooty run by the ...

Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic ...
