"We have observed giant gas planets, such as Jupiter or Saturn, but in another solar system," explains the leader of this research on the HR 8799 system, located 130 light-years away. The study confirms that the James Webb can directly analyze the chemistry of exoplanet atmospheres.

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies.
