SOHO and Hinode Offer New Insight Into Solar EruptionsGreenbelt MD (SPX) Jan 28, 2015 The sun is home to the largest explosions in the solar system. For example, it regularly produces huge eruptions known as coronal mass ejections - when billions of tons of solar material erupt off the sun, spewing into space and racing toward the very edges of the solar system. Scientists know that these ejections, called CMEs, are caused by magnetic energy building up on the sun, which suddenly releases. But the details of what causes the build up and triggers the release are not precisely understood. ... read more |

 NASA-funded FOXSI to Observe X-Rays From Sun An enormous spectrum of light streams from the sun. We're most familiar with the conventional visible white light we see with our eyes from Earth, but that's just a fraction of what our closest star ... more | .. |
 DSCOVR to Observe Space Weather and Earth from Afar News reports of hurricanes forming and predictions about storm paths are familiar occurrences. Less familiar are reports about solar wind and magnetic fields from the sun which can also have an impa ... more | .. |
 Sun's rotating magnetic field may pull lightning toward Earth The push and pull of the sun's magnetic field may encourage lightning strikes by bending the Earth's own magnetic field, allowing an influx of electric particles. Over a five-year period, researchers at the University of Reading recorded a 50 percent increase in lightning strikes when the Earth's magnetic shield was manipulated by the sun. ... more | .. |
 Sun's rotating 'magnet' pulls lightning towards UK The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmo ... more |

Sunspot continues to shoot out solar flares It's no longer just the largest sunspot in more than 20 years; it's the sunspot that just won't quit. The solar region, known as Active Region 12192 (or AR 2192), has been ripping off solar flares for more than a week now, and has shown no signs of slowing down. ... more | .. |
