" Makemake is one of the largest and brightest icy worlds beyond Neptune, and its surface is dominated by frozen methane,” said SwRI’s Dr. Silvia Protopapa, lead author of a new paper soon to be published in The Astrophysical Journal Letters. “The Webb telescope has now revealed that methane is also present in the gas phase above the surface, a finding that makes Makemake even more fascinating. It shows that Makemake is not an inactive remnant of the outer Solar System, but a dynamic body where methane ice is still evolving.”

Methane gas could indicate atmosphere or activity on distant dwarf planet at edges of Solar System
