A newly studied exoplanet, TOI-5205 b, orbiting a small red dwarf star has shown an atmospheric composition that challenges current theories of planet formation.

Using observations from the James Webb Space Telescope, scientists detected gases like methane and hydrogen sulfide but found a surprising lack of heavier elements in its atmosphere.

This is unusual because gas giants are typically expected to have atmospheres enriched with heavier elements, often more than their host stars.

Researchers suggest the planet may have formed in a way that caused heavy elements to sink into its interior, leaving the atmosphere unusually light and chemically distinct, the Daily Galaxy has reported.

The findings suggest that giant planets may be more complex than previously thought and could require new models to explain their formation and internal structure.
