Movie Summary

As we watched this movie about the sun, I realized that while the sun is a main source of life on Earth, it can also be a huge threat to our survival. The sun frequently emits CME's (Coronal Mass Ejections), which are magnetic solar flares that contain at least 25,000,000 J of energy. These flares can be as large as a third of the sun; big enough to surround the whole Earth. Scientists say that if one flare makes direct contact with the Earth, it would cause an apocalyptic crisis. It will burn out and shut down 99.9% of all Earth's energy and electricity. Without any electricity or energy, there will be no power, no water or food, no gas, and no transportation. Without these everyday necessities and appliances, the human population will perish quickly.

Another thing I found interesting about this movie was how magnetism plays a huge role in both the Earth and the Sun. The earth has what is called a magnetosphere, which protects the Earth from the magnetic solar flares that come its way. However, if too many flares hit the magnetic field, it will cause the polarity of the magnetosphere to reverse direction and eventually disappear.
