        The Threat to Earth

        In this video from NOVA’s Sun Lab, learn how a major solar storm could affect life on Earth. Earth’s magnetic shield and thick atmosphere protect it from solar particles; however, a large solar storm could overwhelm these natural defenses. In 1859, unusual space weather resulted in strong auroras and dangerous currents in telegraph lines. Today, society is more at risk because of its reliance on technology that is susceptible to disruption from solar storms. A better understanding of the Sun and improved space weather forecasts can help minimize the potential damage from a large solar storm.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
