NASA will launch five sounding rockets in approx. five minutes to study high-altitude winds and their connection to the electrical current patterns around Earth.
A recent study has found clear evidence on Venus for a type of space weather outburst quite common at Earth, called a hot flow anomaly (HFA). These HFA surges can cause the solar wind to reverse its flow and flood backward.
Curiosity, the mini-Cooper-sized rover, is playing the role of stunt double for NASA astronauts, as it monitors radiation levels on its journey to Mars.
Since 2007, THEMIS has mapped how explosive auroras erupt and solar wind transfers energy to the magnetosphere.
Ten years since its launch, RHESSI has observed more than 40,000 X-ray flares, helped craft a model of how solar eruptions form, and fueled additional serendipitous science papers on such things as the shape of the sun.
It's an alien environment out there: the material in the galactic wind doesn't look like the same stuff our solar system is made of.
Filled with electrons and charged particles, the radiation belts regularly swell and shrink, but no one is quite sure how. A new study sheds light on how those radiation particles escape.
The sun is beginning to stir. By the time it's fully awake in about 20 months, the Goddard team charged with tracking its moods will have deployed a greatly enhanced forecasting capability.
NOAA has devised categories for solar flares and storms. The biggest flares are known as 'X-class flares' based on a classification system that divides solar flares according to their strength.
On July 6, 2011, a comet was caught doing something never seen before: die a scorching death as it flew too close to the sun. The chance to watch it first-hand amazed even the most seasoned comet watchers.
