This one is a little scarier warnings from the past!
If astronomers are right, all life on this planet could be extinguished in less than 30 years from now. Scientists at NASA's Jet Propulsion Laboratory have detected a large object the size of Manhattan possibly on a collision course with Earth. Using their Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), the 10-mile wide object was found approximately 51 million miles from Earth. Scientists believe that during a close encounter with Mars, the asteroid was nudged slightly off its usual orbit and may currently be on a high speed collision course with our fragile planet.
