The earth-space boundary zone is home to some of nature’s most puzzling and alluring phenomena.
Between the blue sky above us and the infinite blackness of space lies a frontier full of enigmas that scientists have only just begun to investigate.
“At the Edge of Space” takes viewers on a spectacular exploration to probe the earth-space boundary zone, home to some of nature’s most puzzling and alluring phenomena: the shimmering aurora (pictured), 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.
