A new study suggests the iron oxide responsible for the red planet's distinctive hue is ferrihydrite, pointing to the bygone presence of water, an important ingredient for life ...
Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.
The Fe3O4 series borrows the name from the chemical compound of black iron oxide, which presents itself in nature as the ...
It contains iron oxide, a chemical compound humans traditionally associate with a different reddish-orange substance: rust. Indeed, this mineral exists on our planet, often in volcanic settings ...
The iron oxide is no longer a pure metal, it is a dull, dark-coloured, metal compound. When you burn magnesium in the air in the same way that the iron did, the magnesium reacts with oxygen to ...

The Red Dust on Mars Might Be a Different Mineral Than Scientists Thought, Shedding Light on the Planet's PastPrevious studies of Martian dust suggested the specific mineral in question was hematite, an iron oxide that can form without water. That’s because spacecraft observations of the compounds had ...
