>>> these pictures were captured by nasa, scientists say from the look of things, the planet earth got very lucky this weekend. they say this amounted to a tsunami on the surface of the sun a few days back. waves of radiation larger than our earth was wide. but luckily it was aimed away from us and thus, wouldn't disrupt communications. scientists fear a large enough solar storm in the next year or two could cripple the power grid on earth.
