The sun's erratic and sometimes volatile behavior has the potential to cause real problems here on Earth, and protecting our planet will require an international effort, according to scientists who gathered recently for a meeting about the effects of solar activity.
Streams of charged particles that fly off the sun can interfere with electronics on Earth and satellites orbiting our planet. For example, during a particularly intense solar storm in 1989, power to an entire Canadian province was knocked out. Since then, other storms have knocked a handful of satellites out of service.
With Earth becoming more and more dependent on technology, the risk from solar flares is only going up, experts say
