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.

WASHINGTON (Reuters) - Astronomers for the first time have deciphered the three-dimensional structure of the atmosphere of a planet beyond our solar system, revealing three layers like a wedding cake ...

Each day, radio signals from key communications and navigation satellites travel freely through a layer of Earth’s atmosphere known as the ionosphere. Floating 50 to 400 miles (80 to 643 kilometers) ...

An asteroid was pegged to hit Earth “imminently,” according to NASA’s Center for Near Earth Object Studies (CNEOS). Fortunately, this one wasn’t big enough to land a team of deep-core drillers on, and ...

Between 50 and 100 kilometers (30–60 miles) above the Earth's surface lies a largely unstudied stretch of the atmosphere, called the mesosphere. It's too high for airplanes and weather balloons, too ...

Astronomers have uncovered the secrets of an alien atmosphere on an exoplanet far beyond our Solar System, and it’s unlike anything we’ve ever seen before. In a scientific first, an international team ...

In a major international project, researchers have conducted the first search for an atmosphere and surface habitability of TRAPPIST-1e with the JWST, the fourth planet in the red dwarf star system ...

Between 30 and 60 miles above Earth’s surface lies a largely unstudied stretch of the atmosphere. It’s too high for airplanes and weather balloons, too low for satellites and nearly impossible to ...
