March 20, 2020. (Click HERE for high-resolution view.) In the vastness of one of the world’s oldest deserts lies a relatively recent geologic feature: the Roter Kamm crater (“Red Comb” in German). An astronaut onboard the International Space Station photographed the crater while orbiting over the Namib Desert. It is […]

SwRI scientists studied the composition of a small shard of a meteoroid to determine that it likely originated from a previously unknown parent asteroid. This false-color micrograph of the meteoroid sample shows the unexpected amphibole crystals identified in orange.

Credit: © Museum für Naturkunde Berlin, Ansgar Greshake Donwilhelmsite is important for understanding the inner structure of the earth. A team of European researchers discovered a new high-pressure mineral in the lunar meteorite Oued […]

Fireball meteorite illustration. On the night of January 16, 2018, a fireball meteor streaked across the sky over the Midwest and Ontario before landing on a frozen lake in Michigan. Scientists used weather radar to find where the pieces landed and meteorite hunters were able to collect the meteorite quickly, […]

Artist’s impression of the collision of two protoplanets. Credit: NASA/SOFIA/Lynette Cook International research team solves theory of how diamonds formed inside protoplanets. Geoscientists from Goethe University have found the largest extraterrestrial diamonds ever discovered – a few tenths of a millimeter in size nevertheless – inside meteorites. Together with an […]

Asteroid 4-Vesta is the second-largest body in the asteroid belt. Uranium-lead dating and other analytical methods tell researchers which meteorites come from Vesta and also when. Credit: NASA It is generally accepted that the inner region of the early solar system was subject to an intense period of meteoric bombardment […]
