Kepler-442c shows strong biosignature indicators, including liquid water and an oxygen-rich atmosphere, making it one of the most promising habitable-zone candidates discovered to date.
Next Steps for Researchers
Scientists plan follow-up observations using the James Webb Space Telescope's spectrograph to confirm the atmospheric composition and search for additional biosignature gases such as methane and ozone.
If confirmed, Kepler-442c would become one of the strongest candidates yet in the search for life beyond our solar system.
