NOVA | At the Edge of Space

Posted by WMHT Web Editor
At the Edge of Space Preview Can scientists unravel the mysterious phenomena that lurk between Earth and space?

Watch Wednesday, November 20, 2013 at 8pm on WMHT TV.

Take a spectacular exploration to probe the earth-space boundary zone, 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. Discovered in 1989, sprites have eluded capture because they flicker into existence for a mere split-second — 40 times faster than an eye blink. NOVA rides with scientists in a high-flying weather observation plane as they hunt for sprites and finally succeed in snaring them in 3D video, gaining vital clues to unravel their mystery. NOVA also combines advanced video technology with stunning sequences shot from the International Space Station.
