"Webb Telescope Uncovers Geothermal Activity on Eris and Makemake in Solar System's Outskirts"

The James Webb Space Telescope has provided evidence suggesting that dwarf planets Eris and Makemake in the Kuiper Belt may be geologically active, despite their frigid, icy origins. By analyzing the infrared spectrum of sunlight reflected off these objects, the telescope was able to identify differences in the hydrogen isotopes found on their surfaces, indicating ongoing geological activity. This discovery challenges previous assumptions about the lack of significant heat sources in the outer Solar System and sheds light on the potential for active geology in distant celestial bodies.
