Io-like volcanic moon may have been discovered orbiting exoplanet WASP-4b - YouTube - Space.com - planetary science

Scientists believe they may have discovered a volcanic exomoon orbiting the exoplanet WASP-4b 635 light years from Earth (right next door).The discovery was made at the European Southern Observatory's 3.6 m/11.81 ft telescope at La Silla,Chile.A large cloud of sodium gas,typical of volcanic eruptions,was observed near the exoplanet.Although we lack the technology to observe exomoons directly,their existance can be ascertained by deduction.*Credits:NASA/Jet Propulsion Laboratory-California Institute of Technology

Habitability of exoplanets studied by NASA's Chandra X-ray Observatory and ESA's XMM-Newton - YouTube - Space.com

The NASA Chandra X-ray Observatory and ESA Multilayer Mirror-Newton X-ray Observatory are screening exoplanets for those exposed to harsh radiation that renders them uninhabitale for organisms.ESO's Extremely Large Telescope is under construction.The Habitable Worlds Observatory (HWO) is a concept NASA is studying for a large space-based ultraviolet/optical/infrared telescope slated for launch in the 2040s on a large launch vehicle such as the SLS or SpaceX Starship.*Credit:NASA/CXC/A.Hobart
