Latest Coronal mass ejection Stories
Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold. Longtime sky watchers say it is the greatest show on Earth.
Ten years since its launch, RHESSI has observed more than 40,000 X-ray flares, helped craft and refine a model of how solar eruptions form, and fueled additional serendipitous science papers on such things as the shape of the sun and thunder-storm-produced gamma ray flashes.
A potent follow-up solar flare, which occurred Friday (Jan. 27, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet.
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.

After years of relative somnolence, the sun is beginning to stir.
A solar flare from Sunday collided with Earth on Tuesday, becoming the largest solar radiation storm since October 2003.
The National Oceanic and Atmospheric Agency's Space Weather Prediction Center issued a geomagnetic storm watch as experts predicted that the biggest solar storm since 2005 is expected to hit Earth Tuesday morning.
A subset of data that helps map out the sun's magnetic fields was recently released from the Solar Dynamics Observatory (SDO).
Scientists have warned of a major solar storm hitting the Earth that could possibly knock out radio signals. Experts expect radio blackouts for a few days after the radiation from the coronal mass ejection (CME) hits our planet.
