To watch: PBS NOVA on Russian Meteor Strike debuts tonight, March 27

"A blinding flash of light streaked across the Russian sky, followed by a shuddering blast strong enough to damage buildings and send more than 1,000 people to the hospital."

Tonight, the PBS program NOVA explores the science questions behind the mysterious events of February 15, 2013, when a 7,000-ton asteroid crashed into Earth's atmosphere.

"Is our solar system a deadly celestial shooting gallery with Earth in the crosshairs? And what are the chances that another, more massive asteroid is heading straight for us?"
