New Mars rover findings revealed

more »
NASA's Mars Curiosity rover has found much higher concentrations of silica at some sites the rover has investigated in the past seven months than anywhere else it has visited since landing on Mars 40 months ago. Silica makes up nine-tenths of the composition of some of the rocks.

Auroral mystery solved: Sudden bursts caused by swirling charged particles

more »
A supercomputer model revealed that the rotation of plasma creates electrical currents in the near-Earth space, ultimately triggering auroral breakups. This overthrows existing theories about how auroral breakups occur.

Magnetic reconnection: Magnetic explosions in Northern lights and solar flares

more »
Just under four months into the science phase of the mission, NASA's Magnetospheric Multiscale, or MMS, is delivering promising early results on a process called magnetic reconnection -- a kind of magnetic explosion that's related to everything from the northern lights to solar flares.
