A new study claims that a mineral found in Mars' dust called ferrihydrite, which forms in the presence of cool water, is likely what gives the planet its reddish hue.

The conclusion suggests that Mars may have rusted earlier in history than previously thought, during a time when water was still present on the surface. Because ferrihydrite forms rapidly in cool ...

Scientists analyzed a sample, which likely contained fatty acids, that transformed into alkanes during the heating process ...

A study suggests Mars takes its red hue from a type of mineral that forms in cool water, which could reveal insights about whether Mars was ever able to support life.

A new plan is forthcoming by the end of the year. Original article source: Cool rocks: NASA's Mars rover shows off its rock core collection ...

Ferrihydrite typically forms quickly in the presence of cool water and so must have formed early on ancient Mars when the planet was still wet. "We are not the first to consider ferrihydrite as ...

Nasa has shared a video of some pretty cool-looking clouds, spotted above the planet Mars. Their Curiosity rover - a robot helping scientists learn more about Mars - captured this amazing video ...

The new analysis points to a different type of iron oxide that contains water called ferrihydrite, which forms quickly in cool water — and likely formed on Mars when water could still exist on ...

Mars' distinctive red color comes from the mineral ferrihydrite, which only forms in the presence of cool water, a new study claims. Ferrihydrite also forms at a lower temperature than other ...
