The Sun Unleashes a Wide, but Benign, CME
NASA’s Solar and Heliospheric Observatory captured this image of a particularly wide coronal mass ejection (CME) that erupted from the sun at 10:23 p.m. EDT on Sep. 27, 2012. The leading edge of the...

On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled away...
NASA’s orbiting Solar Dynamics Observatory (SDO) has recorded more spectacular activity in the Sun’s atmosphere, with a solar flare whipping half a million miles into space, and sending a cloud of electrically charged particles...
Looking more science fiction than just straight science, an amazing tentacle-like eruption on the face of the sun has been captured by NASA’s Solar Dynamics Observatory (SDO). Measuring half a million miles long and...
A new video from a sun-watching spacecraft shows just how much our star has woken up in the last three years. The video gives a side-by-side comparison of footage shot exactly three years apart...
The Radiation Belt Storm Probe mission (RBSP) will explore the Van Allen Radiation Belts in the Earth’s magnetosphere. The charge particles in these regions can be hazardous to both spacecraft and astronauts. Project Scientist...
The Solar Dynamics Observatory (SDO) captured this image of the sun during an M6.1 flare that peaked at 7:44 AM EDT on July 5, 2012. The image is shown in the 304 Angstrom wavelength,...
(multimedia) The sun sent out a flare powerful enough to disrupt radio communications over Europe today, along with an eruption of electrically charged particles that just might sweep past Earth’s magnetic field in time to...
(multimedia) A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet...
An active sunspot is amping up the sun’s activity, and has already unleashed two strong solar flares that triggered weekendgeomagnetic storms on Earth, NASA officials say. The M-class solar flares set off two coronal mass ejections (CMEs) that erupted from the sun on last Wednesday...
