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 ...

As NASA astronauts aim for landings in 2027, geologists find surprises in recently retrieved samples from the far ...

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 ...

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 ...

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.

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

as well as the hypothesis that the lunar surface early on was an ocean of magma, Kring added.
