Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

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

Mars is a cold, dry, desert-like planet. But billions of years ago, scientific evidence suggests that it had a thick atmosphere, which kept it warm enough to support flowing water on its surface. So, ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

Scheduled to launch late this year, the Mars Atmosphere and Volatile Evolution (MAVEN) will be the first mission devoted to understanding the upper atmosphere of Mars. The goal of MAVEN is to ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
