NASA's James Webb Space Telescope (JWST) has captured direct images of carbon dioxide in the atmosphere of planets outside our solar system.
The discovery was made in a planetary system called HR 8799, located 130 light-years away, providing evidence that the planets formed similarly to Jupiter and Saturn.
The images were captured using Webb's coronagraph, blocking the light from stars to observe faint nearby planets and detect specific gases like carbon dioxide.
Understanding the formation of giant planets helps researchers comprehend the potential habitability of smaller, Earth-like planets in the future.
