A vast impact crater near the moon’s south pole was formed by an asteroid moving at more than a kilometre a second, releasing energy when it struck equivalent to 130 times that of all the nuclear ...

The Moon’s biggest scar does not sit quietly in the background. The South Pole-Aitken basin is a vast impact structure more ...

Eons ago, in the frigid depths of our solar system, a dramatic collision occurred between two icy worlds. Instead of a catastrophic smash-up, the two bodies "kissed," merging temporarily like a ...

To our best of our understanding, the Moon formed from Earth following a colossal impact. A Mars-sized world we nicknamed Theia slammed and merged with the primordial Earth, throwing material into ...

A half century after NASA's Apollo 17 lunar module lifted off the moon's northeastern near side quadrant, planetary scientists still don't completely understand when or how our moon first formed. They ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Earth and the Moon both record evidence of a 'lost' period of bombardment. (NASA) Tiny crystal grains trapped inside a ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun. Artist’s impression of the collision between ...

The study of our Moon has experienced a renaissance in recent years, particularly through ongoing and planned sample return missions, which allow us to study lunar rock samples at unprecedented detail ...

Even though humans have pondered the moon since the first of us looked skyward, there is still much we still don’t know about it. One of these unsolved questions is its origin story. We think the moon ...

Research into the formation of the moon was conducted by scientists at the Weizmann Institute of Science in Rehovot, Israel and the Technion-Israel Institute of Technology located in Haifa. Results of ...
