NASA has just released data from the orbiting WISE telescope that indicates there are a lot more asteroids out there that can hit us then they previously new about. While letting us know there is no need to panic, NASA has indicated that they are paying much closer attention then they had before. More asteroids tand larger ones than previously thought are in orbits that potentially could collide with Earth. Impacting with Earth could create a host of environmental hazards not to mention extensive damage and loss of life. A small asteroid of 40 meters in size impacting earth would be equivalent to the detonation of a 3 megaton nuclear bomb.
