This model reveals how vastly different the atmosphere was on ancient Earth, and how life may have first emerged. The key to unlocking the secrets of distant planets starts right here on Earth.

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of ...

A team led by researchers at the University of Tokyo has created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. The work has been ...

The Moon may not have much of an atmosphere, mostly because of its weak gravitational field (whether it had a substantial atmosphere billions of years ago is debatable). But it is thought to presently ...

New research suggests Mars' missing atmosphere -- which dramatically diminished 3.5 billion years ago -- could be locked in the planet's clay-covered crust. Water on Mars could have set off a chain ...

Astronomers say they are one step closer to finding a habitable, Earth-like planet beyond our Solar System, with the discovery of an atmosphere on a rocky planet. They detected traces of helium in the ...

Earth's atmosphere is like a protective blanket that surrounds our planet and is composed of a mix of gases. While many trace gases are present in tiny amounts, most of the air we breathe comes from ...

For the first time since its discovery in 1920, Pluto is entering the outer solar system—a journey that’s slowly thinning out its atmosphere.
