Scientists have confirmed that an impact crater in Australia's Pilbara region is Earth's oldest known asteroid strike, dated at over 3 billion years old. The findings challenge previous estimates and reveal how ancient collisions shaped our planet's geological history.
·Australian Pilbara crater confirmed as world's oldest asteroid impact site through multiple recent studies
·Impact crater dated at more than 3 billion years old, with previous estimates off by up to half a billion years
·Ancient asteroid impacts created geological features now being studied to understand early Earth conditions
·Moon's largest impact crater contains valuable materials that NASA's Artemis missions may explore
·Pluto's unexpected young, smooth plains discovered by New Horizons suggest geological complexity beyond simple impact scarring
