Astronomers believe streaks on Mars may be dust, not water

Mars (NASA / CNN) -- New research suggests that signs of water on Mars may not actually be water at all.

Back in 2011, astronomers discovered dark streaks on the slopes of Mars. Instead of water, according to a new study published by the journal "Nature Geoscience", those streaks may actually be the result of granular flows like sand and dust. Courtesy: NASA / CNN

Back in 2011, astronomers discovered dark streaks on the slopes of Mars.

It had some believing that there could be water beneath the surface, allowing life to exist on the red planet.

But according to a new study published by the journal "Nature Geoscience", those streaks may actually be the result of granular flows like sand and dust.

So does that mean there's no water on Mars after all? Not exactly.

Researchers say there's plenty of evidence for water on Mars, such as ice on the planet's subsurface and poles.
