A seemingly small planetary neighbor may play a larger role in Earth’s climate than previously thought. Mars is only about ...

Mars' gravity has a surprisingly large influence on Earth, affecting our planet's tilt and orbit and thereby contributing to climate cycles lasting hundreds of thousands to millions of years, new ...

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 ...

Mars is half the size of Earth, with one-tenth of our planet’s mass, and at the nearest point in its orbit is over 33 million miles away. Yet new research highlights the extraordinary influence the ...

NASA’s twin ESCAPADE spacecraft will uncover how the Sun stripped Mars of its atmosphere. Mars is a very different world ...

A new study suggests Mars's gravitational pull significantly impacts Earth's orbit, driving the intensity of ice ages and warm periods. Learn how planetary cycles control our planet's long-term ...

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...
