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

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 ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

Because cosmic ray particles are electrically charged, they change course when they encounter magnetic fields. This means scientists can’t trace them back to their sources. Gamma rays, however, travel ...

(Phys.org)—During a powerful solar blast on March 7, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's ...
