Shenzhen's recently unveiled mega-scale cultural facilities, including the Natural History Museum, are attracting Hong Kong residents for weekend trips. This trend signifies an evolution in northbound spending beyond dining, with visitors like Raymond Leung planning cultural excursions to see attractions such as dinosaur fossils and meteorites.
Amateur astronomer Joël Lapointe discovered a 390-million-year-old meteorite impact crater in a remote part of Quebec using Google Maps. Initially skeptical, scientists, including Gordon Osinski of Western University, confirmed the discovery through an expedition, finding shatter cones and impact melt rock. The crater, named Uhackatik in collaboration with the Ekuanitshit Innu council, is a significant find for Canadian earth science.
Researchers from UBC and international teams used advanced nickel isotope analysis to identify the meteorite that wiped out dinosaurs 66 million years ago as a rare CO chondrite, solving a decades-old puzzle about the extinction event.
Lake Bosumtwi in Ghana, a near-perfect blue circle, is a 10.5 km wide meteorite impact crater formed ~1 million years ago. Revered by the Ashanti as the 'Lake of Souls', it holds spiritual significance and has concentrated valuable minerals like gold due to geological alterations from the impact.
Scientists found that soil studied by India's Chandrayaan-3 rover closely matches the chemical makeup of ALHA 81005, the first meteorite confirmed to be from the Moon. The finding links measurements from the "Shiv Shakti Statio" to the meteorite found in Antarctica, suggesting both represent the same broad category of magnesium-rich lunar crust material.
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.
