Between the blue sky above and the infinite blackness beyond lies a frontier that scientists have only just beballoon to investigate. In "At the Edge of Space", NOVA takes viewers on a spectacular exploration of the Earth-space boundary that's home to some of nature's most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites. Only discovered in 1989, sprites have eluded capture because they exist for a mere split-second-40-times faster than an eye blink. NOVA rides with scientists in a high-flying weather observation plane on a hunt for sprites, finally snaring them in 3D video and gaining vital clues to unraveling their mystery. Combining advanced video technology with stunning footage shot from the International Space Station, "At the Edge of Space" probes the boundary zone and offers an entirely new perspective on our home planet.
