A chunk of asteroid or comet whizzing through space slammed into the moon and left a 728-foot-wide pit, the largest known fresh crater in the solar system.
Astronomers have named this new crater McGetchin, in honor of lunar scientist Tom McGetchin, whose mathematical model in 1973 predicted how debris scatters after a major space collision.
Meanwhile, McGetchin Crater, which sinks about 141 feet deep, is already beginning to age.
As NASA maps out its future Artemis missions to the moon, some scientists might advocate for a future visit to McGetchin.
A lunar impact of McGetchin's scale is expected only about once every 132 years.
