What happened 14,300 years ago is barely believable. A paper published this week in Earth and Planetary Science Letters details a study of tree rings in the French Alps that reveals evidence of an ...

Scientists have discovered evidence of an extraordinarily powerful solar storm that bombarded Earth 14,300 years ago, at the end of the last Ice Age. This event was far more intense than any solar ...

The most powerful solar particle storm known to date struck Earth in 12350 BC, according to a new study that sets a “new worst case scenario” for humanity from such colossal space weather events. The ...

Scientists call the particle collisions and interactions they study “particle events.” A particle event is a particle collision or interaction that is observed by some type of particle detector.

Solar energetic particle (SEP) events and coronal mass ejections (CMEs) are central features of solar activity that significantly influence space weather. SEPs are high‐energy particles expelled ...

Space flight conditions within the protection of Earth's gravitational field have been shown to alter immune responses, which could lead to potentially detrimental pathology. An additional risk of ...

Shortly after NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission’s science team revealed that the asteroid could be active, or consistently discharging ...

An electron antineutrino races to Earth from outer space at nearly the speed of light, carrying 6.3 petaelectronvolts (PeV) of energy. Deep in the ice sheet at the South Pole, this high-energy ...
