It's rare for any observatory to directly image a planet beyond our solar system, called an exoplanet, but the powerful James Webb Space Telescope has captured four of them in the stellar system HR 8799.

"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.
