Secrets of the Sun – Nova National Geographic Special Full Documentary. Shooting hot plasma at almost 1 million miles per hour, and containing 99 percent of all matter within our solar system, our Sun is an amazing thing. Its core temperature is a brilliant 27 million degrees Fahrenheit, and it is ever-moving.
Secrets of the Sun explores the sun using new spacecraft and advanced, Earth-based telescopes, allowing scientists to see the sun like never before. The scientists’ work help us understand what is going on in the sun, including new ideas on how to predict and track solar storms that can shut down our communication and power grids. This understanding could help stabilize our infrastructure against the storms in the future, keeping us ‘in the light’ so to say.
