Quick Summary

A researcher at NASA discovered a recently formed crater on the Moon named McGetchin, measuring 222 meters wide, believed to have been caused by an asteroid or comet collision in spring 2024. Scientists consider impacts of this scale to be once-in-a-century events. The Lunar Reconnaissance Orbiter (LRO) detected the crater as a bright spot with a dark halo and it is noted as the largest newly discovered crater in the solar system according to a study published on September 16th. This finding aids understanding of lunar geology and prepares future crewed missions to the Moon.

Story summary

NASA’s Lunar Reconnaissance Orbiter (LRO) discovered a massive crater on the moon's near side, larger than the Roman Colosseum, measuring about 728 feet across and up to 141 feet deep, in May 2024. The impact that formed this crater was caused by an asteroid or comet fragment roughly the size of a three- to six-story building. This event is estimated to occur only once every 132 years, making it a rare opportunity for researchers studying lunar geology and future moon missions. The crater was initially missed by Earth-based telescopes but spotted later in data analysis, providing valuable insights into the moon's surface changes as NASA plans to establish a base there.

Narrative

Although the crater had been there for years, it was not discovered until Robert Wagner, a researcher with NASA’s Lunar Reconnaissance Orbiter (LRO), noticed it in a new scan of the Moon’s surface. The crater appeared as a “large bright spot circled by a dark halo” by the LRO probe, which has been studying the Moon since 2009.
