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.

Results from a new study show that the water-rich iron mineral ferrihydrite may be the main pigment behind Mars’ reddish dust.

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.
