A new way to create Saturn's radiation belts

A team of international scientists from BAS, University of Iowa and GFZ German Research Centre for Geosciences has discovered a new method to explain how radiation belts are formed around the planet Saturn.

The case of the relativistic particles solved with NASA missions

Encircling Earth are two enormous rings—called the Van Allen radiation belts—of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky ...

NASA listens in as electrons whistle while they work

Space is not empty, nor is it silent. While technically a vacuum, space nonetheless contains energetic charged particles, governed by magnetic and electric fields, and it behaves unlike anything we experience on Earth. In ...

Recreating a heavenly chorus of plasma waves on Earth

Recent experiments at the Large Plasma Device (LAPD) at the University of California, Los Angeles, have successfully excited elusive plasma waves, known as whistler-mode chorus waves, which have hitherto only been observed ...

NASA spacecraft records 'Earthsong'

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
