NOVA: Secrets of the Sun DVD - AV Item

AV Benefits:

Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.

Description

• It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the Sun as they never have before and even re-creating what happens at the very center of the Sun in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before--but never in the modern era of satellite communication. Secrets of the Sun reveals a bright new dawn in our understanding of our nearest star--one that might help keep our planet from going dark.
