Luckily, thanks to Earth s swirling, molten core (and the magnetic field it provides), we are protected from this planet-sterilizing onslaught like an invisible force field All that science has a beautiful side effect: It makes the auroras! The Northern and Southern lights are the result of the solar wind and its dance with Earth s magnetic field and polar atmosphere. It s Earth s own cosmic light show!
