The study, authored by a Russian astrophysicist and published in a preprint on arXiv, suggests that these extreme cosmic rays ...

Most of the cosmic rays we get here on Earth come from the sun, but we’ve also picked up particles that we think are coming from other galaxies. Cosmic rays can tell us about space and the universe.

Researchers think that during the most active part of the sun's 11-year cycle, known as solar maximum, fewer cosmic rays reach the planet because its magnetic field is strengthened by the constant ...

Scientists have revealed a hidden trigger of lightning that could resolve a centuries-old weather mystery. Earth is struck by some 44 bolts of lightning each second, on average. Despite this, ...

Kilonova explosions from neutron star collisions may damage atmospheres and threaten life if nearby, according to a new study ...

It protects us from stray cosmic rays coming from elsewhere in the galaxy—but the effects of storms on the sun’s surface can also affect our telecommunications networks. The wind would also pose a ...

There are many risks associated with human space exploration. NASA has been planning for these missions to make our astronauts return home safely.

This is because the dominant source of radiation on the ISS is galactic cosmic rays (GCR), which are deflected by the Sun’s magnetic field. GCR intensity is highest during solar minimum when the ...

Just like how blue light has a more energy than red light, cosmic rays come in different energy values. The highest-energy cosmic rays, which are some of the most energetic particles in the ...

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right ...

Cosmic rays can come from distant supernovas, black holes and even the sun, and they constantly lash Earth's upper atmosphere. When they splinter as they interact with air molecules, they produce ...
