Mars is not just a colder, dustier version of Earth. It is a planet soaked in high‑energy particles that batter rock, metal, ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt. These variations, known as Milankovitch cycles, ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the ...

Despite its small size, Mars seems to have a huge impact on the orbital cycles that govern Earth’s climate, especially those ...

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 extent to which Mars is quietly tugging on Earth's orbit and shaping the ...

Just as the Moon's gravity drives the oceans' tides, Mars's gravity is now understood to play a significant role in shaping ...

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position ...
