An international research team has identified the specific origins of most of the Martian meteorites that are now on Earth. They’ve traced the meteorites to five craters where they were […]
Geoscientists from the University of Cologne have led an international study to determine the origin of the huge piece of rock that hit the Earth around 66 million years ago […]
[University of Cologne] Scientists have pinpointed the origin and composition of the asteroid that caused the mass extinction 66 million years ago, revealing it was a rare carbonaceous asteroid from […]
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began.
Mars’ tadpole craters are small, young craters whose crater rims are incised by one or more exit breaches but lack visible inlets.
Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have […]
To investigate impact vaporization for planetary atmosphere formation, we have studied the thermodynamic state generated by the shock wave due to a high-velocity impact, called the shock field.
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, including young […]
Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth’s atmosphere 12,800 years ago, causing a widespread […]
Ammonites were not in decline before their extinction, scientists have found.
