Mars may have significant amounts of water underneath the surface

In 2018, scientists made the incredible discovery that they had found a "stable body of liquid water" on Mars.

A new study takes that one step further and suggests that the water thought to be responsible for dark streaks on the Red Planet may be coming from well below the surface.

The new study, published in Nature Geoscience, suggests that the recurring slope lineae (RSL) may have a "deep underground origin" and not flows of water either on or just underneath the surface, as previously thought.

"We suggest that this may not be true," the study's co-author, Essam Heggy, said in a statement.

"We propose an alternative hypothesis that they originate from a deep pressurized groundwater source which comes to the surface moving upward along ground cracks."
