Researchers discover source of super-fast electron rain

UCLA scientists have discovered a new source of super-fast, energetic electrons raining down on Earth, a phenomenon that contributes to the colorful aurora borealis but also poses hazards to satellites, spacecraft and astronauts.

Spacecraft reveal new details of magnetic reconnection

The space environment around Earth is characterized by interactions between Earth's magnetic field and nearby plasma. A key physical process in these interactions is magnetic reconnection, in which two adjacent field lines ...

Researchers find clues to how hazardous space radiation begins

Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, ...

Steve over the picket fence

Strange ribbons of purple light that appeared in the sky—known as Steve—became the subject of debate in 2017, as their origins were unbeknown to scientists. Now, photographs of this remarkable phenomena have been studied ...

Scientists discover what powers celestial phenomenon STEVE

The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according to new research. In a new study, ...
