Impact craters are formed when an object from space such as a meteoroid, asteroid or comet strikes Earth at a very high ...

An ancient crater lake in the southern highlands of Mars appears to have been fed by glacial runoff, bolstering the idea that the Red Planet had a cold and icy past.

Jezero crater lies exactly on the border between the ancient highland region of Terra Sabaea, where rocks from 4.1-3.7 billion years ago can still be found, and the 3.9 billion year old Isidis ...

The new image reveals a distinct crater south of the basin, and basin walls that gently slope to a depth of around 5,000 feet (around 1,500 meters) below the surrounding Martian surface.

Stretching 1,550 miles (2,500 kilometers) wide and 8 miles (13 km) deep, the South Pole-Aitken basin, as the tremendous hole is known to Earthlings, is the oldest and deepest crater on the moon ...

The South Pole-Aitken basin is the moon's oldest and largest visible crater—a massive geological wound 4 billion years old that preserves secrets about the moon's early history, much like a ...

A view of the moon's largest impact feature, the South Pole-Aitken basin. This region stretches between Aitken crater and the south pole (hence the name).

These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show Crater Hale in the Argyre basin of the southern hemisphere of Mars.
