In the spring of 2024, a comet or asteroid the size of a mid-rise building struck the Moon, carving a crater 728 feet wide into its ancient surface — an event of this scale occurring only once every century or so. The impact went unwitnessed and unnoticed until NASA scientist Robert Wagner, reviewing archival photographs from the Lunar Reconnaissance Orbiter in late 2025, recognized the unmistakable signature of something new. Named McGetchin, this crater reminds us that the solar system is not a finished place — that even familiar celestial neighbors are still being quietly, violently remade.
