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.
The object formed when a meteorite slammed into Earth more than 800,000 years ago.
