Our Sun could erupt at any moment, spewing a vast wave of charged particles toward Earth that could leave millions of people without power for up to a year. Learn about the latest missions to protect our planet from this potentially devastating threat.

Our Violent Sun

The birth of our Solar System was both violent and chaotic. As planets formed around our Sun, gravity and luck determined their fate: some are tossed into the Sun, others thrown into interstellar space, never to return. It is survival of the fittest, on an interplanetary scale.
