NASA spacecraft discovers a huge new crater on the moon

<p>Scientists have discovered a crater on the Moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.</p> <p>The steep-sided hole — about 222 metres across and up to 43 metres deep — is the solar system’s biggest known impact crater carved out in recent times.</p> <p>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.</p> <p>“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.</p> <p>NASA’s Lunar Reconnaissance Orbiter spotted the crater on the moon’s near side in May 2024, soon after it was formed by an incoming fragment of an asteroid or comet.
