One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin ...

Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...

The James Webb Space Telescope measured a potential moon-forming disk encircling an exoplanet, NASA recently announced, inviting researchers to observe and study moon formation as it happens, while ...

Two immense canyons on the moon's far side that rival Earth's Grand Canyon were produced by a cataclysmic collision nearly four billion years ago, according to new research published on Tuesday.

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

For the first time, the chemical composition of a moon-forming disk around a planet has been revealed. The James Webb Space Telescope has, for the first time, measured the carbon-rich concoction that ...

How did the Moon form? Was it from a collision, as has been the longstanding theory, or could it have been captured by the Earth early in our planet’s formation? This is what a recent study published ...

The moon's orbit isn't a perfect circle. Instead, it's more stretched out, kind of like an oval, which means its distance from Earth varies by about 30,000 miles (48,000 km). The surface of the moon ...
