X-ray observatories Chandra and XMM-Newton study nearby stars' radiation to assess exoplanet habitability.

NASA's Chandra X-ray Observatory and ESA's XMM-Newton are being used to explore whether nearby stars could host habitable exoplanets based on radiation emitted. Astronomers use X-ray data to determine exoplanet habitability concerning lethal radiation from their host stars. This research will guide future telescope observations in finding habitable planets like Earth.
