Astronomers have identified a rare planetary system 190 light-years from Earth featuring a hot Jupiter sharing its orbit with a mini-Neptune closer to the star. This configuration was once considered nearly impossible. New observations from the James Webb Space Telescope provide fresh insights into how the planets formed.

Astronomers using the James Webb Space Telescope have detected thick water ice clouds on Epsilon Indi Ab, a cold gas giant resembling Jupiter. The finding, led by researchers at the Max Planck Institute for Astronomy, reveals less ammonia than expected in the planet's atmosphere. This challenges existing models and advances techniques for studying distant worlds.
