Methane gas revealed on dwarf planet Makemake by JWST observations
Los Angeles CA (SPX) Sep 11, 2025 A Southwest Research Institute-led research team has made the first detection of gas on Makemake, a distant dwarf planet in the outer Solar System, using NASA's James Webb Space Telescope (JWST). The discovery marks Makemake as only the second trans-Neptunian object after Pluto to show confirmed gaseous emissions, identified as methane. "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 au ... read more |
