Earth's atmosphere is made up of layers that vary in temperature and pressure. It is where Earth's weather occurs.

A project led by the University of Washington to better understand our atmosphere’s complexity is a finalist for NASA’s next generation of Earth-observing satellites. STRIVE will ...

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace ...

Earth's atmosphere protects the planet in more ways than one. This thin band of air is unique to Earth, and we wouldn't exist without it.

K2-18b probably can’t host life as we know it, but it orbits in a cosmic sweet spot where water vapor in the atmosphere could turn into liquid.

Scientists have discovered a hole in the atmosphere that allows ozone-depleting compounds and other chemicals to bypass the atmosphere’s natural “washing machine” layer.

That same cloud gave rise to our entire solar system, including our star, the sun. Keep reading to learn more about Earth's different layers, its atmosphere, and what makes the "blue planet" unique.

A team of researchers has found pollutant metals in Earth's stratosphere — the second layer of our atmosphere — and traced them back to rockets and satellites.

Earth is the only planet known to support life. Learn about what Earth is made of and where it came from.

New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will continue to warp the environment.

The Earth’s atmosphere is described as a fragile coat wrapping around the planet, comparable in scale to an apple’s skin protecting the fruit. For more than half a century, even before the ...

A Ripple Effect Across Planets The chain reaction of a stellar flare begins high above a planet’s surface. When incoming protons collide with molecular nitrogen in the atmosphere, they create ...
