Bright deposits in permanently shadowed craters on Ceres are thought to harbor water ice. However, the evidence for water ice presented thus far is indirect.
Mars’ tadpole craters are small, young craters whose crater rims are incised by one or more exit breaches but lack visible inlets.
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 […]
After detouring through a dune field to avoid wheel-rattling boulders, NASA’s Perseverance Mars rover reached its latest area of scientific interest on June 9. The route change not only shortened […]
We examine high spatial resolution Galileo/NIMS observations of the young (~1 My – 20 My) impact features, Pwyll and Manannán craters, on Europa’s trailing hemisphere in an effort to constrain […]
Ceres, the largest asteroid in our Solar System, harbors a dark secret: Extremely young ice deposits in permanently shadowed craters near its poles. If that sounds vaguely familiar, it’s because […]
We have performed topographic and geological mapping of 19 large impact features on Ganymede and Callisto in order to gather morphometric and crater age data that allow us to quantify […]
Discrepancies have emerged concerning the application of sulfur stable isotope ratios as a biosignature in impact crater paleolakes.
In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this […]
The ice-exposing impact crater at the center of this image is an example of what scientists look for when mapping places where future astronauts should land on Mars.
