Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...

Add Yahoo as a preferred source to see more of our stories on Google. Exposure to cosmic radiation varies with altitude—higher altitude means greater exposure. Photograph by JSC/NASA When we gaze up ...

Recent airborne science flights to Greenland are improving NASA’s understanding of space weather by measuring radiation exposure to air travelers and validating global radiation maps used in flight ...

Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.

The Martian radiation environment is characterised by a complex interplay between primary cosmic radiation and secondary particles generated through interactions with the thin Martian atmosphere and ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

Space is a harsh environment. We’re all familiar with the big risks from television – asteroids, solar flares, lack of air, extreme temperatures, and the occasional testy alien ships. What we don’t ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

According to a radiation weather expert, a stream of high-energy particles from a supernova explosion may have triggered a sudden loss of altitude on a passenger plane. In late October, a JetBlue ...
