The most powerful solar flare in four years exploded over the sun late Monday, according to NASA.
The magnetic instability that caused the flare also unleashed a blast of charged particles that should hit Earth's atmosphere tonight, possibly sparking auroras farther south than usual, experts say.
The most powerful explosions in the solar system, solar flares occur when magnetic field lines on the sun cross, cancel each other out, then reconnect.
These "explosive reconnections" release huge amounts energy as heat—in this case, a short blast measuring roughly 35 million degrees Fahrenheit (19 million degrees Celsius), according to physicist Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory, or SDO. Full Story

Hmm....it's one of characteristic if the earth will be doomsday.....hohoho lol
@Didik: but I hope it won't occur in this age, at least after God call me back :p
