NASA’s Webb Detects Carbon Dioxide in Exoplanet Atmosphere

Posted by in category: space

It’s a big step forward in understanding exoplanets.

Humanity’s giant space telescope has captured evidence of carbon dioxide in a planet outside of the solar system for the first time. According to a Thursday press release.

The detection was made using Webb’s Near-Infrared Spectrograph (NIRSpec) and took the form of a small bump between 4.1 and 4.6 microns on the spectrum related to the exoplanet’s atmosphere. The evidence helps shine a light on how planets are formed.


NASA’s James Webb Space Telescope has captured the first clear evidence for carbon dioxide in the atmosphere of a planet outside the solar system. This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet.
