Scientists who work on long-term climate patterns usually stay close to Earth. The data is here, the records are clearer, and ...

The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too ...

Thin, seasonal ice may have protected ancient lakes on Mars, allowing liquid water to last for decades despite cold ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

New climate modeling suggests that small lakes on ancient Mars could have stayed liquid for decades, even in a generally cold environment. Small lakes on early Mars may have stayed in liquid form for ...

Researchers uncover how Mars affects Earth’s orbit, offering new insight into the planetary forces behind ice ages.

Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing.
