The Earth’s atmosphere is experiencing an accelerated rate of atmospheric escape, leading to a faster loss of gases into space than previously observed. This revelation, founded on recent scientific ...

Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and possibly tens of millions — of years, according to data released Thursday by the National Oceanic and Atmospheric ...

"Everything we have ever designed to go into space has been one mission, one life. It's sort of crazy." The world at large is working to stop the fast-progressing degradation of Earth's environment.

High-resolution isotope data show that a modern-like, oxygen-rich atmosphere was not established until 410 million years ago, supporting a 2-billion-year transitional oxygenation of Earth’s surface.

The global average concentration of CO2 surged by 3.5 parts per million to reach 423.9 ppm last year, fuelling worries that ...

A rocky, Earth-size planet located in our Milky Way galaxy may have an atmosphere around it, according to new research, raising the possibility that it could also have liquid water on its surface and ...

Telluric lines, once an astronomer's bane, have a new purpose. Astronomers are known for peering deep into the universe, but now, their observations might also help us better understand what's ...

A European company that seeks to develop orbital spacecraft for cargo, and eventually humans, took a step forward this week with a test flight that saw its “Mission Possible” vehicle power up and fly ...

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 ...

New reports out of the NOAA and Scripps Institution of Oceanography suggest that the carbon dioxide (CO2) levels in Earth's atmosphere haven't been this high in millions of years. It's a striking ...
