Dr Lucie & Dr Karl at 15 million degrees (44)

Dr Lucie Green is a Solar Researcher. She studies our natural power source – that Great Nuclear Reactor in the Sky, the Sun.

Come along for the ride with me, Dr Karl, as Dr Lucie helps discover how fusion works, why the light we see is ancient (as old as we are), how to tell if there's an astronomer in your car, and the best place to view planet alignments and magellenic clouds. Shirtloads with Dr. Karl is Out Of This World - with added physics.
