The U.S. Senate has dropped a House-approved plan that would prepare the United States to defend itself from an attack from any electromagnetic pulse source - whether it would be from a natural solar flare or the detonation of a space-located nuclear weapon by enemies intent on destroying America's infrastructure, according to a representative who

On September 1, 1859, a vast coronal mass ejection from the Sun hit the Earth. It was so powerful that telegraph equipment caught fire from the induced electromagnetic flux, and people merely standing near metal objects received serious electrical shocks. It could happen again at any time -- and this time, it could shut down our high-tech

Finally, some excitement from the Sun! On August 1, 2010, the entire Earth-facing side of the sun erupted with all sorts of activity. There was a C3-class solar flare, a solar tsunami, multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio

The first of possibly two incoming CMEs hit Earth's magnetic field today at approximately 1740 UT (1:40 pm EDT). As a result of the impact, a moderate (Kp=6) geomagnetic storm is underway. High-latitude sky watchers should be alert for auroras after nightfall

For ages, people have been saying: “Solar is a great, clean, renewable energy source, but it is just too expensive. Other energy sources, like nuclear, may have some (or serious) environmental risks, but they are cheaper

The solution to the problem of continued use of petroelum products to generate energy and for use in transportation has been with us for some time. This is solar energy collected above the atmosphere via satellites, then beamed down to collection points on Earth for redistribution to where it is needed. Above the atmosphere, where there is

This morning around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was sunspot 1092. At about the same time, an enormous magnetic filament stretching across the sun's northern hemisphere erupted. NASA's Solar Dynamics Observatory recorded the action:
