Transcript for Instant Index: Space Station and the Moon; Avalanche Buries Skier
Our "instant index" tonight starts with a reminder that we're all just a pin price in the vast universe. Look. That is the moon. And there in the corner of your screen is the international space station. That little dot, a kind of intergalactic mosquito buzzing around the heavenly body. It was snapped by a stargazer in bu has aries. And another jaw-dropping view. A skier making his way down a mountain in greece. Hears a rumble, looks over his shoulder and sees an avalanche coming toward him, gaining ground. Watch it again. It's a wall of snow coming. And he says he was buried by it, but you see him clinging to a tree branch. He eventually digs his way out and the encounter was caught on tape by his helmet camera. And we have proof tonight that one man's trash is another man's really big treasure. This was the mess a man walked into, a new homeowner in new york who bought a bungalow at a bargain for $300,000. The garage was full of trash left there by the previous owner. But it turns out, in that pile, were 70,000 paintings and drawings including a horse, that woman in recline. They are the work of the late armenian artist arthur pa imagine yan. And the work has an estimated worth of $30 million. And the new owner gets to keep the prize. And if you see something out there you love for our "instant index," tweet it to m me @dianesawyer.
