"James Webb Space Telescope Detects Methane and Water on 'Warm Jupiter' Exoplanet"

The James Webb Space Telescope (JWST) has detected methane and water vapor in the atmosphere of a "warm Jupiter" exoplanet located around 163 light-years away. This is a significant discovery as the detection of methane using space-based spectroscopy has been rare. By observing the planet's transit in front of its parent star, astronomers were able to analyze the combined spectra and identify the presence of specific molecules. The team also used thermal emissions during the planet's eclipse to further study the atmosphere. The findings provide insights into the exoplanet's features, formation history, and potential for supporting life.
