The stock market is dipping, inflation is on the rise and there is no end in sight to the war in Ukraine. But not all the news is bad: Our planet just got a bit safer, thanks to NASA.

In a feat previously relegated to the realms of science fiction, NASA scientists successfully deflected an asteroid from its path.

On Sept. 26, DART, a spacecraft the size of a commercial dryer, hit a nonthreatening asteroid called Dimorphos — and proved that we humans might be capable of mounting an Earthly defense, should a killer asteroid one day head our way.
