NASA finds a 'once in a century' lunar crater, bigger than the Roman Colosseum

A researcher at NASA has found a massive, recently-formed crater on the Moon, a rare occurrence that only happens "once in a century or even longer", according to scientists. The crater, dubbed "McGetchin," measures 730 feet (222 metres) wide, NASA said in a blog post. It is believed to have been created in the spring of 2024 from a comet or asteroid colliding with the Moon, with researchers describing the object that caused it to be the size of a building three-to-six stories high. "Scientists estimate that an impact of this magnitude happens on the Moon about once in a century or even longer," NASA said in the blog post.

Such a large-scale event is estimated to occur only once every 132 years, researchers said, making this a treasure trove of information as NASA prepares to build a base for astronauts on the moon. “This event constitutes a statistically rare, effectively once-in-a-lifetime observation,” the scientists wrote in one of two studies appearing on the subject Wednesday in the journal Science Advances. Although the crater had been there for years, it was not discov...
