M-class Solar Flare
2014-04-03 06:12:35

Karen C. Fox, NASA's Goddard Space Flight Center On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event. 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 in the layer where GPS and communications signals travel. To...

University of Cambridge Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created. New footage put together by an international team led by University of Cambridge researchers shows how entangled magnetic field lines looping from...

An NJIT physicist is a collaborator in the discovery of a new structure in Earth’s inner radiation belt -- a zebra-striped structure of highly energized electrons that could endanger humans in space and also damage low-earth navigation and communication satellites. Newark, NJ (PRWEB) March 19, 2014 An NJIT physicist is a collaborator in the discovery of a new structure in Earth’s inner radiation belt -- a zebra-striped structure of highly energized electrons that could endanger humans...

Van Allen Probes Helping To Refine Space Weather Computer Models
2014-03-10 07:45:30

redOrbit Staff & Wire Reports - Your Universe Online Data from the Van Allen Probes has been combined with a high-powered computer model to help researchers test and improve the forecast model to determine how the two giant near-Earth radiation belts they orbit can affect technology in space, NASA officials reported on Friday. The Van Allen radiation belts, which are teeming with rapidly-moving particles and a space weather system that varies in response to incoming solar particles...

sunspot
2014-03-01 05:57:56

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
2014-02-25 08:24:39

[ 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...

Space Weather Around Venus Is Harsher Than That Around Earth
2014-02-21 14:01:57

[ 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....
