The James Webb Space Telescope has taken a closer look at a mysterious planet that is like nothing found in the solar system and may have had a watery past.
Astronomers witnessed a young Jupiter-size planet as it carves out spiral-shaped cavities in the disk of planet-birthing gas and dust that surrounds its parent star.
Gaseous planets close to their star could see their hydrogen atmospheres evaporate, leaving behind helium that could be detected by the James Webb Space Telescope.
