Heliophysics - Space Weather Topics

  • Severe Space Weather--Social and Economic Impacts

    2009April 6, 2011

    A new NASA-funded study details what might happen to our modern, high-tech society in the event of a 'super solar flare' followed by an extreme geomagnetic storm. Some of the conclusions might surprise you.

  • Fake Astronaut Gets Hit by Artificial Solar Flare

    2009April 6, 2011

    Researchers are about to subject a fake astronaut complete with blood cells and simulated human tissue to an artificial solar flare. How the unlucky volunteer emerges from the radiation storm will reveal for the first time how much of a threat severe solar flares pose to Astronautsen route to The Moonand Mars.

  • NASA Sees the Dark Side of the Sun

    2009April 6, 2011

    Today, NASA researchers announced an event that will transform our view of the Sun and super-charge the field of solar Physicsfor many years to come.

  • The Sun's Sneaky Variability

    2009Sept. 20, 2011

    It might not be obvious to the naked eye, but the sun is a variable star. A sensor slated for launch onboard the Solar Dynamics Observatory will probe the sun's "sneaky variability" with better time and spectral resolution than ever before.

  • Sunbathing at Solar Max

    2000April 6, 2011

    NASA scientists say that Solar Maximum is now in full swing. Does that mean you're more likely to catch a sunburn at the beach? The answer is "no," and this story explains why.

  • Solar Storm Warning!

    2000April 6, 2011

    An interplanetary shock wave from a solar coronal mass ejection is expected to pass our planet this Thursday. The disturbance could trigger aurora at middle-latitudes. This story includes animations of the CME and associated solar flares, as well as observing tips for aurora borealis.

  • Small Sunspot, Big Flare

    2000April 6, 2011

    One of the biggest and brightest optical flares of the current sunspot cycle erupted this weekend. The flare was a whopper, but the sunspot group it came from wasn't.

  • Space WeatherMission Nears Launch

    2000April 6, 2011

    An innovative satellite called IMAGE, slated for launch on March 15, 2000, will revolutionize our understanding of Earth's magnetosphere and improve Space Weatherforecasting.

  • Coming Soon: Better Space Storm Warnings

    2000April 6, 2011

    In the past, predicting the onset of a geomagnetic storm was difficult. Forecasters couldn't say with much precision how long it would take for a solar coronal mass ejection to reach Earth. Now scientists have created a model that reliably forecasts the arrival of these billion-ton gas clouds in the vicinity of our planet.

  • The RADAR Cop in Space

    2000April 6, 2011

    NASA's IMAGE satellite, scheduled for launch on March 25, will revolutionize our understanding of Earth's magnetosphere. Space Weatherdata from the innovative spacecraft will be freely available to the public on the web and elsewhere. NASA scientists are developing plans for down-to-earth listening stations that HAM radio operators can build to capture the data themselves.
