Kuiper belt
The Kuiper belt is a donut-shaped region of icy bodies extending beyond the orbit of Neptune. It is home to Pluto and the most known dwarf planets.

Significance
JWST has been instrumental in examining celestial bodies and exoplanets. The latest findings provide insights into the Kuiper Belt and into the solar system.

Findings
The study revealed light hydrocarbons and complex organic molecules on the surfaces of these dwarf planets, which are believed to be the result of methane irradiation.

Theory
Researchers believe that methane is processed inside these objects and regularly resupplied to their surfaces, supporting studies on other Kuiper Belt Objects.
