Saturn's radiation belts: A stranger to the solar wind

The radiation belts of Earth and Saturn differ more strongly than previously assumed. In these belts, very energetic particles, such as electrons and protons, move around the planet at high velocities - captured by its magnetic ...

Shining light on solar energetic particles and jets

A team of astronomers, led by PhD researcher Malcolm Druett of Northumbria University at Newcastle, have taken a big step forward in understanding a 30-year-old mystery in the process of formation of solar flares. Druett ...

Space weather model simulates solar storms from nowhere

Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs. These solar storms often come first with some ...

Next stop: A trip inside the Sun's atmosphere

Every so often the sun emits an explosive burst of charged particles that makes its way to Earth and often wreaks havoc on power grids, aircraft and satellite systems. When clouds of high-speed charged particles come racing ...

Image: Northern lights over Canada

Just hours after the winter solstice, a mass of energetic particles from the Sun smashed into the magnetic field around Earth. The strong solar wind stream stirred up a display of northern lights over northern Canada.

Heliophysics CubeSat to launch on NASA's SLS

Just a bit bigger than a box of cereal, one of the first CubeSats to travel in interplanetary space will be NASA's miniature space science station, dedicated to studying the dynamic particles and magnetic fields that stream ...
