Oxygen-rich laboratory melts retained extra oxygen under pressure, revealing a possible transport mechanism within Earth.

New research reveals that molten rock can absorb far more oxygen than expected, potentially helping explain how Earth's ...

Earth's shape can be tested in surprisingly simple ways without relying on space photographs. The strongest part of the ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...
