Astronomy Sky's the Limit!

Planet Earth is an oasis of life, but without the Sun, our home planet would be a drastically different, inhospitable place. The Sun’s electromagnetic energy makes life on Earth possible; solar power also generates clouds, cleans our water, and drives ocean currents, thunderstorms, and hurricanes. For three decades, NASA scientists have studied the unique relationship between the Sun and the Earth, and they are particularly interested in the role of the Sun in Earth’s energy balance. This short film explores the vital connection between the Earth and the Sun, and includes an interview with Dr. Robert Cahalan, head of the NASA Goddard Climate and Radiation Branch.
