Scientists at Los Alamos National Laboratory, a United States Department of Energy facility in New Mexico, used a supercomputer to model nukes' anti-asteroid effectiveness. They attacked a 1,650-foot-long (500-meter) space rock with a 1-megaton nuclear weapon - about 50 times more powerful than the U.S. blast inflicted on Nagasaki, Japan, to help end World War II.
