Normal gases, like the air you breathe on Earth, are made up of atoms bouncing around. Atoms consist of a positively charged bundle of particles called the nucleus and negatively charged particles ...

Plus: Why are hurricanes so powerful? Are winds on other planets like they are on Earth? The answer, my friend, is blowin' in ...

High above us, the atmosphere is teeming with life. Birds, bats and insects share the airspace, but divide it into different ...

Weather forecasters talk about wind shear a lot during hurricane season, but what exactly is it? I teach meteorology at Georgia Tech, in a part of the country that pays close attention to the Atlantic ...

Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using ...

Atmospheric motion vectors (AMVs) are derived estimates of wind velocity obtained by tracking the motion of identifiable features, most commonly cloud elements, in sequential satellite imagery. The ...

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet ...

Two decades of observations by a pair of orbiting spacecraft have enabled scientists to track the whirlwinds called "dust devils" that regularly pirouette across the surface of Mars, providing a ...

Artist's rendering of a solar storm hitting Mars and stripping ions from the planet's upper atmosphere. Mars' atmosphere, once as thick as if not thicker than Earth's today, is leaking into space. "We ...
