Millions of charged particles are rushing toward earth after a gigantic solar flare on Tuesday.Bad news for NASA’s latest mission, but good news for sky-watchers: Those charged particles also collide with the earth’s atmosphere to produce the ethereal-looking northern lights.
Normally, northern lights, or auroras, are only visible at or near the pole, to which solar particles are channeled by the earth’s magnetic field. But when the massive solar storm reaches the earth tonight, northern lights could be seen as far south as Boston and Cleveland.
