Scientists have identified the world's oldest impact crater in Australia's Pilbara region, dating back 3 billion years. Analysis of zircon and apatite minerals in ancient rocks at the North Pole Dome crater provided evidence of a meteorite strike during the Archean eon, offering insights into early Earth.
Un meteorite ha colpito l'Australia occidentale oltre 100 milioni di anni fa, creando un cratere di 4 km e scatenando una pioggia d'oro. La scoperta è stata fatta da geologi vicino a Kalgoorlie.
A meteorite found in the Sahara, NWA 12774, suggests the early solar system may have contained a lost planetary embryo. Analysis of clinopyroxene crystals indicates formation under extreme pressure, implying a parent body much larger than a typical asteroid, possibly approaching lunar size.
Researchers used the James Webb Space Telescope to measure the mass of a 10-billion-light-year-distant dormant black hole, and a Sahara Desert meteorite provided clues about a long-lost protoplanet in our solar system.
Three months after a meteorite struck a house in Koblenz, Germany, scientists are still waiting for access to the largest fragments for official classification. While small pieces have been analyzed, at least 20 grams are needed for international registration.
