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.

For years, astronomers have sought a way to directly observe the atmospheres of exoplanets, worlds orbiting distant stars. Unlike indirect detection methods, such as transit observations or radial velocity measurements,

Astronomers used the James Webb Space Telescope to directly capture images of the planets in the star system HR 8799, which will help contextualize our existence in the universe.
