Experiment shows that a nuclear explosion could save the planet from a deadly asteroid impact Nature Physics A blast of X-rays from a nuclear explosion should be enough to save Earth from an incoming asteroid,

Scientists and the space community have long wondered how they can defend our precious planet from such a disaster. Now, researchers at US-based Sandia National Laboratories have taken a significant step toward protecting the Earth from large space rocks.
