IT’S OKAY TO BE SMART

The Auroras

  • Aired: 03/06/2013

  • Rating: NR
Space might seem like an empty place, but the area surrounding Earth is constantly being bombarded by waves of charged particles released by the Sun: The solar wind. 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. The visual result? The Auroras.
