New footage of a meteorite exploding across the sky over the Russian region of Cheliabinsk near the Ural mountains.<br/> <br />Amateur videos continue to emerge days after the meteorite struck the area, damaging buildings, shattering glass and sending more than 1,000 to hospital with cuts and scrapes.<br/> <br />Search teams have descended on Lake Cherbarkul, where the meteorite crashed Friday, to look for remains, but have been unable to find any large pieces so far.<br/> <br />Residents have also joined the search and claim to have found a few fragments themselves.<br/> <br />The Russian space agency said the fireball was travelling 30 km per second and although it did not kill anyone, the meteorite caused around $33 million in damage.<br/> <br />This prompted scientists on Monday to discuss the possibility of an early warning system for the planet that would encompass telescopes and anti-asteroid missiles.<br/> <br />(SOUNDBITE) (Russian) VLADIMIR LIPUNOV, HEAD OF THE SPACE MONITORING LABORATORY WITH MOSCOW STATE UNIVERSITY, SAYING:<br/> <br />"How many telescopes do we need? That depends on the field of view. It is now possible to build telescopes of 4 to 8 square degrees. We need 10 to 20 telescopes around the Earth, dozens of them."<br/> <br />NASA estimates the meteorite was 17 metres across and weighed about 10,000 tonnes before entering Earth's atmosphere and exploding with nuclear bomb force.
