Latest Solar Energetic Particles Stories
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun.
They are the darkest and coldest places on the surface of the moon, but deep in the craters of the polar regions, electrical activity may be creating a kind of “sparking” that has driven changes in lunar soil evolution.
In order to better understand what powers solar flares, NASA officials announced on Thursday that they were turning to the MESSENGER spacecraft orbiting Mercury in order to get a closer look at these intense bursts of radiation resulting from sunspot-related magnetic energy release.

The sun is a ferocious, hot mess, and this week it showed off through a coronal mass ejection just how messy it can get. An active region on the sun fired off two M-class flares and two coronal mass ejections (CMEs) this week.
When the sun launched a moderate, or M-class, solar flare May 17, 2012, it was still one of the largest eruptions seen since late January when our star began to rouse from an anomalously long quiet period.
The sun unleashed an X1.8 class flare that began at 1:12 PM ET on January 27, 2012 and peaked at 1:37. The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5.
On October 25, 2006 a Delta II rocket launched from Cape Canaveral carrying two nearly identical spacecraft.
NASA is preparing to send astronauts back to the Moon and on even longer journeys to Mars. With crews out in space for extended periods of time, the chances go way up that they'll be caught in the middle of a storm.
