The topic of this episode was the Aurora. The
first topic of discussion was the visual aspect of the aurora. The reason we see the aurora is
because of Earth's magnetic field. They expressed Earth as basically a bar
magnet with looping magnetic field lines. Atomic oxygen is found in the upper
atmosphere where it is closer to the suns radiation. This makes the atmosphere extremely radioactive, giving the ability to corrode most metals. Because of the way
they are created, we are now able to predict these aurora with greater and greater accuracy.
