Karen C. Fox, NASA's Goddard Space Flight Center A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. Scientists track sunspots that are part of active regions, which often produce large explosions on the sun such as solar flares and coronal mass ejections, or CMEs. Each time an active...

X-class solar flare

[ Watch the Video: SDO Observes Strong X-class Solar Flare ] Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically...

[ Watch the Video: What's Causing Crazy Weather On Venus? ] Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the Journal of Geophysical Research, space weather around Venus is much harsher than what is experienced around Earth. Scientists have discovered that the space weather around Venus can have such large explosions that they are bigger than the entire planet. They also said that these giant explosions can happen multiple times per day....

Mid-Level Solar Flare Emitted By Sun Feb. 3, 2014
2014-02-04 12:12:58

Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST. NASA released images of the flare as captured by NASA's Solar Dynamics Observatory. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere...
