Scientists Propose Destroying Asteroids with Nuclear Bombs to Save Earth

Humanity is more prepared than ever to face space threats. Chinese researchers led by Wang Xiaowei have proposed an innovative planetary defense strategy to protect Earth: digging a crater into an asteroid, inserting a nuclear warhead, and detonating it. This method, published on July 9, 2026, promises to be the most effective option against devastating impacts.
