March solar storms heated Earth's atmosphere

The recent solar activity did more than spark pretty auroras around the poles. Researchers say the solar storms of March 8th through 10th dumped enough energy in Earth’s upper atmosphere to power every residence in New York City for two years. Although the influx of

What does a solar storm sound like?

To get an idea what does a solar storm sound like, a University of Michigan researcher has created a "sonification" of measurements from two spacecraft during the most recent storm. The researcher who created it is Robert Alexander, a University of Michigan de

Radiation storm and CME heading toward Earth, geomagnetic storm and aurora events expected

A solar radiation storm is in progressaround Earth. At the moment, the storm is classified as minor, which means it has little effect on our planet other than to disturb HF radio transmissions at high latitudes. Bigger effects, however, may be in the offing. The

Sun blasted CME toward Mars

A bright CME blasted off the sun on Oct. 22nd, and it appears to be heading for Mars. Analysts at the Goddard Space Weather Lab expect the cloud to reach the Red Planet on Oct. 26th (forecast track). A brief discussion of what CMEs can do to Mars follows this SOHO
