A study suggests that a meteor impact around 56,000 years ago may have triggered a massive landslide in the Grand Canyon, leading to the formation of a paleolake by damming the Colorado River, with evidence found in driftwood and sediments in Stanton's Cave. Further research is needed to confirm this connection.
A study suggests that a giant meteor impact around 56,000 years ago, forming Barringer Crater, triggered a massive landslide in the Grand Canyon that dammed the Colorado River, leading to a significant flooding event and geological changes in the region.
The Aorounga structure in the Sahara Desert, Chad, is an 8-mile-wide impact crater formed by a "city-killer" asteroid around 345 million years ago. Captured in a 2013 photo by an astronaut aboard the ISS, the crater's eye-like appearance is due to its two rings, with migrating sand dunes surrounding it. These dunes, known as barchan dunes, move significantly over time, as tracked by satellite images. The crater may be part of a "crater chain," with smaller craters nearby suggesting fragments of the original meteor impacted the area.
Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has long puzzled scientists about its origin. A recent study using advanced microscopy techniques has identified the glass as originating from a meteorite impact on Earth's surface. The study found minerals in the glass that can only form under high temperature and pressure conditions, providing evidence for the meteorite impact theory. However, the exact location and size of the parental crater remain unknown, leaving more mysteries to be solved.
Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has been identified as originating from the impact of a meteorite on Earth's surface. Advanced microscopy techniques revealed the presence of zirconium oxide minerals, including cubic zirconia and a rare polymorph called ortho-II, indicating high temperatures and pressures consistent with a meteorite impact. However, the location of the parental crater remains unknown, raising further questions for future investigations.
Libyan desert glass, a mysterious yellow glass found in the Libyan desert, has been the subject of debate among scientists for almost a century. Advanced microscopy technology has now revealed that the glass originated from a meteorite impact on Earth's surface. The study identified different types of zirconium oxide minerals in the glass, indicating high temperatures and pressures that can only be achieved through a meteorite impact or atomic bomb explosion. However, the location of the parental crater, where the meteorite hit, remains unknown, posing more mysteries to be solved.
A meteor impact on the moon was captured by multiple telescopes in Japan on February 23, 2023. The resulting crater is estimated to be around a dozen meters in diameter.
