One of the best-preserved craters on Earth lies deep within the SaharaDesert On Asteroid Day, the Copernicus Sentinel -2 satellite objective takes us over the almost-perfectly circular Tenoumer Crater in Mauritania.
Tenoumer Crater, noticeable in the center of the image, is 1.9 km (1.2 miles) large. The rims of the crater increase some 110 m (360 feet) high above the base, however the bottom of the crater is covered with an around 200 to 300 m (650 to 980 feet) thick layer of sediments.
It was long disputed whether the crater was formed by a volcano or meteorite. Scattered rocks around the crater, comparable to basalt, produced the impression of an ancient volcano. Yet a better exanimation of the structure exposed the crater’s solidified ‘lava’ was in fact rock that had actually melted by a meteorite effect.
The crater beings in a huge plain of rocks that are so ancient they were transferred numerous countless years prior to the very first dinosaurs strolledEarth Even though it lives in ancient rock, Tenoumer is much more youthful, varying in age in between 10,000 and 30,000 years of ages.
This Sentinel -2 false-color image, caught on May 16, 2022, reveals the dry landscape surrounding the crater which appears in differing tones of brown, tan, and orange.
Asteroid Day is the United Nations- approved day of public awareness of the threats of asteroid effects, held each year on 30June More than one million asteroids have actually been found in the Solar System, with much more anticipated to be out there. ESA’s Planetary Defence Office, ESA’s Near-Earth Object Coordination Center, and astronomers around the world are admiring keep us safe, collaborating to guarantee we understand well ahead of time if an asteroid is found on a clash.
