The water frost on Mars' volcanoes is only about as thick as a human hair, but it’s a lot of water – the equivalent of 60 Olympic-sized swimming pools, researchers found.

A team of scientists has detected patches of water frost on Mars’ tallest volcanoes, challenging existing ideas of the Red Planet’s climate dynamics and providing key insights for future exploration. According to a news release from Brown University, the discovery was made atop Mars’ Tharsis volcanoes, the tallest volcanoes in the entire solar system. Volcanoes in the Tharsis region are up to 100 times larger than those anywhere on Earth, according to NASA.

"What we're seeing may be a remnant of an ancient climate cycle on modern Mars, where you had precipitation and maybe even snowfall on these volcanoes in the past."RELATED: Mars rover camera hit with charged particles after solar flare reaches planetThe study says frost forms for only a few hours after sunrise before it evaporates in sunlight.

Water frost on Mars: On the top of immense volcanoes, a briefly icy landscapeThe formation of water frost is common on Earth, especially in winter when atmospheric water vapor condenses and freezes on the surface. On Mars, the atmosphere is about 100 times less dense than on Earth, but it too contains water vapor.
