Nuclear weapons might save the world from an asteroid strike – but we need to change the law first

The schlocky 1998 Bruce Willis movie Armageddon was the highest grossing film of that year.

Earth vs. asteroids: humans strike back

Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan’s Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu.
