Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key ...

Researchers have found measurable traces of lithium pollution left in the upper atmosphere when a rocket burned out in space, ...

Fast-flowing jetstream air currents have shifted further southwards, dragging rain-bearing weather away from Australia.

Scientists measured the pollution caused by the SpaceX rocket re-entry fireball in Earth's atmosphere. The team detected a ...

The world is warming. This fact is most often discussed for Earth's surface, where we live. But the climate is also changing ...

In a paradox of air pollution, a decrease in man-made pollutants led to more methane in our atmosphere. And natural wetlands released more of the planet-warming gas at the same time ...

We now have a clearer picture of how the atmosphere cleanses itself of air pollution and harmful gases. With their recent study, an international team headed by scientists from the National Oceanic ...

Pluto’s atmosphere is hard to observe from Earth. It can only be studied when Pluto passes in front of a distant star, allowing astronomers to see the effect the atmosphere has on starlight. When this ...

Carbon dioxide makes up only about 0.04% of the Earth’s atmosphere, but that seemingly small figure ignores threat CO2 poses to the climate. Carbon dioxide accounts for 79% of U.S. greenhouse gas ...

Every day, fragments of Elon Musk’s internet megaconstellation are streaking across the sky and vaporizing long before they ever reach the ground. One to two Starlink satellites are now routinely ...

Our atmosphere is about 78% nitrogen and 21% oxygen, with traces of other things like water and carbon dioxide. It's an odd mix compared to the atmospheres of other planets. Jupiter and Saturn are ...

Since Mariner 4 flew by Mars more than five decades ago, scientists have understood the red planet to be a cold, dry world. Now they know why. After looking at the first six months of data collected ...
