"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if ...

Mars is about half Earth’s size and roughly a tenth its mass — not really the sort of planet you’d expect to leave ...

New simulations show red planet affects Milankovitch cycles that shape how solar energy is distributed on Earth over millions ...

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

Study finds Mars helps pace Earth's ice ages through gravity. Remove Mars, and a major 2.4-million-year climate rhythm ...

At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the ...

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

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.

Why did the ice ages occur? If you need a scapegoat, a new study by Stephen Kane of UC Riverside suggests pointing the finger ...

Researchers discovered Mars subtly affects Earth’s orbit and axial tilt. These small changes help trigger ice ages and ...

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