Scientists used data from NASA's ACE mission to study jets of electrons streaming from the sun known as electron strahl. This aids understanding of the giant space weather system around Earth.
In the summer of 2011, scientists recorded some of the best movies of sprites ever taken -- movies that can be used to study this poorly understood phenomenon and the forces that create them.
On July 23, 2012, a massive cloud of solar material erupted off the sun. NASA Goddard scientists clocked the giant cloud, known as a coronal mass ejection, or CME, at speeds between 1,800 and 2,200 miles per second.
A key ingredient for 'night shining clouds' comes from outer space. Scientists have detected bits of 'meteor smoke' imbedded in them.
The pace of changes quicken at the boundary of interstellar space.
Curiosity is equipped with an instrument that measures space radiation, which was turned on shortly after launch on Nov. 26, 2011. The instrument has been sending back data during its trip to Mars.
On July 24, 1992, a joint JAXA/NASA mission launched, becoming the vanguard for a set of coordinated missions to study Earth's magnetic environs.
The DFS rocket launched successfully on July 24, 2012 from White Sands, NM with nominal data from 3 of the 4 spectrometers aboard. It's primary goal is to significantly advance the state of the art in short wavelength observing solar spectrometers.
On July 14, 2012 a CME crashed into Earth's magnetic field and triggered the most sustained display of auroras in years, giving the world a taste of things to come when Solar Max arrives in 2013.
NASA's High Resolution Coronal Imager satellite, or Hi-C, has captured the highest-resolution ultraviolet images ever taken of the sun's corona.
