Last week, beachgoers off an Iranian island were met by an eerie sight. The sand turned bright red as if the shoreline was ...

The Fe3O4 series borrows the name from the chemical compound of black iron oxide, which presents itself in nature as the ...

The shoreline off an Iranian island turned bright red after getting battered by heavy rains in a scene straight out of the ...

That’s because spacecraft observations of the compounds had not identified traces of water, indicating the iron oxide must have appeared after all of Mars’ ancient lakes and rivers had evaporated.

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.

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 ...

Scientists have uncovered that iron oxides, previously thought to trap phosphorus, actually help convert it into a ...

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 ...

Previous 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 ...
