The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars.

Fresh Lunar Craters Discovered

A Southwest Research Institute-led team of scientists discovered two geologically young craters - one 16 million, the other between 75 and 420 million, years old in the Moon's darkest regions.

The discovery of an ancient ring-like structure in southern Alberta suggests the area was struck by a meteorite large enough to leave an eight-kilometre-wide crater, producing an explosion strong enough to destroy present-day Calgary, say researchers from the Alberta Geological Survey and University of Alberta.

Picture this: A massive asteroid almost as wide as Rhode Island and about three to five times larger than the rock thought to have wiped out the dinosaurs slams into Earth.

Large and small, hundreds of thousands of craters scar the surface of Mars, hollowed out by a multitude of asteroids and comets that impacted the Red Planet throughout its history.

A Spectacular New Impact Crater on Mars

Context Camera (CTX) images showed a likely new impact crater formed at this location between July 2010 and May 2012, and now a HiRISE image provides details about this recent impact event.

Newly Named Craters on Mercury

The International Astronomical Union (IAU) - the arbiter of planetary and satellite nomenclature since its inception in 1919 - recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors or other contributors to the humanities.
