'Mars Went From Habitable To Uninhabitable,' New Study Hints On What Caused The Red Planet To Dry Out

Mars is the 4th planet from the Sun and the Solar System's second-smallest planet. There are numerous mysteries surrounding Mars.

The Red Planet's significant transition from a warm and watery to a chilly and dry planet could have been primarily driven by greenhouse gases apart from carbon dioxide (CO2).

Missions to Mars have discovered riverbanks and deltas, indicating that the planet once had rivers and lakes.

A recent research says that unexpected events in the planet's deep history may have caused it to end up losing its water.

As per the study published in the journal Science Advances, the river-forming environments on early Martian surface were hot and moist at first, then wet and cold later.

The researchers investigated the records of red planet's rivers to learn more about Mars water and atmosphere.

"People have proposed various theories, but we're not sure what made the climate to change so significantly, We'd like to understand why, especially as it's the only celestial body we know has gone from liveable to uninhabitable."
