If the scientists could very precisely measure the proportions of lutetium and halfnium in moon rocks compared to other ...

This theory, known as the lunar magma ocean (LMO) model, describes how the debris from the impact of Theia coalesced to form the moon, with the energy from this event causing the newly formed moon ...

This is consistent with the Lunar Magma Ocean hypothesis — known as the LMO — which holds that the moon’s crust formed as magma cooled roughly 4.4 billion years ago. The moon was much closer ...

The moon quickly began to cool. Most of the lunar magma ocean solidified almost right away by geologic standards—about a single millennium. But once about 80% of the magma had solidified ...

Our planet's Moon might look dead and stagnant from our vantage point here on Earth, but a new study suggests it was moving ...

NASA's Juno spacecraft has discovered a giant volcanic hot spot on the surface of Jupiter's hellish moon Io. The eruptions in ...

Ancient lunar basins that formed within about 100 million years after the lunar magma ocean solidified have fully relaxed, owing to the high temperature of the lower crust, and thus escaped detection.

"Whereas Arizona’s Grand Canyon was carved by water over the last 5 to 6 million years and from integrated paleocanyons that ...

The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power ...

Another explanation is that, following the impact that formed the basin, a huge ocean of metal-rich magma pooled inside of the lunar crust and solidified into a dense slab.

A NASA spacecraft orbiting Jupiter has just witnessed some of the most extreme volcanic eruptions ever seen in the solar system, coming from a giant underground magma chamber on the "tormented" Jovian ...
