Episode notes

Stars go through different stages of evolution, from main sequence to red giant and eventually to white dwarf. Neutron stars form after a supernova and may become pulsars if they spin rapidly. Red dwarf stars are smaller, cooler, and can potentially exist for up to 14 trillion years. Brown dwarf stars are not massive enough to emit light. The Sun, nearing middle age at 4.5 billion years old, will expand in size over time, eventually engulfing inner planets before its demise. The cyclical nature of celestial events brings a sense of calm and acceptance of the transient existence of life.

Sunset flimflam! Auroras! Eclipse tips! Let’s get to know the center of our solar system, the Sun, as the April 8th eclipse approaches. What is it made of? How big is it? Will it explode soon? Why can’t I stare at it? And why is it wearing sunglasses? Dr. Michael Kirk and almost-Dr. India Jackson are brilliant and charming Heliologists who have both worked with NASA’s heliophysics departments. Get to know them and also the giant hot plasma ball we revolve around. You’ll never (not look at it) the same.
