A half-century-old Moon rock, sealed away since the Apollo era, has just forced scientists to rethink what they thought they knew about our nearest neighbor. By slicing into a sample that had been treated as routine for decades, researchers uncovered a ...

Trivalent titanium occurs only when the amount of oxygen available for chemical reactions is low. Thus, the abundance of trivalent titanium in ilmenite could tell us about the relative availability of oxygen in the Moon's interior when the rock formed, around 3.8 billion years ago.

A subtle chemical trace locked inside ancient lunar samples is reshaping how scientists understand the Moon’s earliest history, pointing to the unexpected presence of oxygen during its formation. Drawing on recent research discussed by The Conversation,

Decades after being sealed away, Apollo-era lunar samples are revealing unexpected chemical signatures that challenge long-standing assumptions about the Moon’s composition.

Lunar rocks collected by Apollo astronauts more than half a century ago are providing a fresh take on the moon's mysterious magnetic field, scientists reported Wednesday.Samples to be retrieved by future moonwalkers in NASA's new Artemis program should ...

The year's first supermoon and meteor shower will sync up in January skies, but the light from one may dim the other. An analysis of feldspar crystals within the oldest magmatic rocks in Australia has provided a unique insight into Earth's ancient mantle ...

MOON rock and meteorite samples have been examined by Keighley schoolchildren. Pupils at Holycroft Primary School had the chance to investigate the specimens as part of a British Science Week project. Through the UK Research and Innovation initiative, youngsters across the school – from nursery to Year 6 – became scientists for a week.
