The Magnetic Sun

Our future literally depends on the sun. The video introduces the sun as a star. It explains the plasma magnetic fields, sunspots, solar flares, coronal mass ejections, and more. It concludes with how we rely on the sun, how we protect...

How does the sun give us light and heat? Discover what's really going on inside the centerpiece of our solar system in a brief video. The content includes common misconceptions about the sun's source of energy, how the simple elements...

Phil takes us for a closer look at the two-octillion-ton star that rules our solar system. We look at the sun's core, plasma, magnetic fields, sunspots, solar flares, coronal mass ejections, and what all of that means for our planet....

Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge...

Solar storms is the topic of part four of the five-part series on the secrets of the sun. Learn about auroras, CMEs, solar flares and the damage it could cause here on Earth. The most interesting fact in this clip is the fact that solar...

Our atmosphere is pretty amazing! How does it minimize the effects of solar weather? Scholars discover Earth's first line of defense against the sun—the magnetosphere. The activity, one of several in a sun unit from NOVA, explains how...

Sunspots, solar flares, coronal mass ejections ... why is the sun so stirred up? Scholars watch animations of the interaction between moving plasma and magnetic fields and discuss the sun's behavior. The activity, part of NOVA's sun...

Learn how sun spots observed by Galileo sparked interest in the sun that continues today. Sun spots, solar wind, new discoveries, and space exploration of the sun are all covered in this informative video. This clip would be a great...

The seventh segment in an eight-part unit promotes the idea of concentrating the sun to increase the power of a photovoltaic panel. Pupils learn about devices used such as reflectors or lenses.

Images and diagrams of the Sun, solar phenomena such as sunspots and flares, space weather, Earth's magnetosphere and upper atmosphere, the aurora, and more.
