New Information On The Invisible Belt That Saves Earth From Radiation

New Information On The Invisible Belt That Saves Earth From Radiation

A NASA-led study of the Van Allen radiation belts has uncovered new information about the invisible “shield” that keeps harmful ultrarelativistic electrons from the Earth. Just last year, the probes reported the existence of a new, previously-unknown third belt thousands of kilometres above the Earth.

This Crazy Contraption Weighed A Single Electron 13x More Accurately

This Crazy Contraption Weighed A Single Electron 13x More Accurately

Last week, scientists from the Max Planck Institute for Nuclear Physics published the most exact value ever observed for the weight of a single electron — a value 13 times more accurate than the previous estimate. And the Penning trap, the kooky looking device shown above, was crucial in obtaining…

Electrons Can Split Into Two

Until now, electrons have been regarded as elementary particles — which means that scientists thought they had no component parts or substructure. But, for the first time, electrons have been observed decaying into two separate parts — causing physicists to rethink what they know about the particles.
