redOrbit Staff & Wire Reports - Your Universe Online 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. As the US space agency explained, it can be difficult understanding some of the processes on the sun when you are forced to rely solely upon the...

Aurora Australis Glowing Over Concordia Station
2012-07-20 15:27:23

A stunning image showing Aurora Australis — the Southern Lights — glowing over Concordia station in the Antarctic, one of the remotest places on Earth, on 18 July 2012. It was taken by ESA-sponsored scientist Alexander Kumar and his colleague Erick Bondoux from about 1 km from the station, located in the Antarctic at 75°S latitude. The French—Italian Concordia station's programme of research includes glaciology, human biology and the atmosphere. ESA uses the base to...

Incoming Coronal Mass Ejection Coming On June 16
2012-06-15 13:39:44

[ Watch the Video ] Lee Rannals for redOrbit.com 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. NASA said the first flare lasted for three hours, and peaked on June 13 at 9:17 a.m. EDT.  The CME associated with the flare traveled up at approximately 375 miles per second. The second flare peaked...

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. But the event was not just an additional solar wake-up call; it produced something that has the solar physics community puzzled and scientists from the University of New Hampshire poised to analyze a singular dataset gathered during the event by a European satellite called PAMELA - short...

NASA Captures Another Massive Solar Flare On January 27: Video
2012-01-30 10:35:37

[ Watch the Video ] 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. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow....

Image 1 - STEREO Celebrates Five Years of Science

[ Watch Video 1 ] | [ Watch Video 2 ] On October 25, 2006 a Delta II rocket launched from Cape Canaveral carrying two nearly identical spacecraft. Each satellite was one half of a mission entitled Solar TErrestrial RElations Observatory (STEREO) and they were destined to do something never done before — see the entire sun simultaneously. The sun rotates, of course, so there's no part of the sun we haven't at some point observed from our vantage point on Earth. But watching this...

"We have one solar maximum left to learn what we need to know before we send humans back to the Moon." "“-Prof. Robert Lin, Chairman of the Solar Sentinels Working Group, SPD, June 2006 NASA - In his 1970s book, Space, James Michener depicted a fictional Apollo mission that lost its crew to radiation from a massive solar flare. He based his tale on what easily might have been but for lucky timing: a massive flare on Aug. 7, 1972 occurred between Apollo 16 (April) and Apollo 17...
