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 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 team discovered that each type of iron oxide exhibited varying degrees of ... While the researchers initially hypothesized that the phosphorus compounds' surface structure would play a role ...

“The start of the heavy rain of the famous Red Beach of Hormoz. Serasima tourists seeing this rain is amazing,” read the caption. The reel has left Instagram users amazed. Many have responded with red ...

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 ...
