Earth would certainly be different without its rusty red neighbor. No Mars in the night sky, no target for future human exploration. Now, however, scientists say this scenario would result in much ...

The idea that Mars could affect Earth’s climate sounds dramatic, since climate change is usually linked to cars, factories, forests, and oceans, not distant planets. Yet Earth is part of a solar ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy lifting was more challenging than I initially thought." When you purchase ...

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 ...

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 ...

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, ...
