The James Webb Space Telescope took a closer look and found that TOI 5205b's atmosphere has fewer heavy elements than planets like Jupiter or Saturn, which hints at some unusual building blocks.
The planet might have formed in a totally unexpected way, with heavy elements moving inward as it grew.
Discovered by Carnegie astronomers, this planet is making astronomers rethink how planets form, especially around stars that don't have much material to work with.
As researcher Anjali Piette put it, There may be more massive planets around red dwarfs than we previously thought.
