Findings from the research may enable Melosh's team toenhance an asteroid impact effects calculator he developed to estimate whatwould happen if asteroids of various sizes were to hit the Earth.

NASA’s Perseverance rover has stunned experts after finding some strange-looking rock composed of spherules on the surface of Mars. The team studying the Perseverance rover’s discoveries were ...

Not all spherules form this way, however. They also form on Earth by rapid cooling of molten rock droplets formed in a volcanic eruption, for instance, or by the condensation of rock vaporized by ...

NASA's Perseverance Rover has stumbled across a rather intriguing rock on the rim of the Jezero Crater on Mars. The rock, which was closely examined and photographed by the rover, appears to be ...

Alternatively, the spherules might be volcanic droplets or impact melt fragments, created by the rapid cooling of molten rock during explosive events like eruptions or meteorite impacts.

This kind of pressure can only be delivered by the catastrophic impact of outer space. In 2023, in the same region, a different team found evidence of impact spherules, suggesting meteorite ...
