Illustration of a rocky exoplanet and its star. The star is in the background at the lower left and appears somewhat, but not significantly, smaller in the sky than the planet. It has a bright orange-red glow, and appears to have an active surface. The planet is in the foreground to the upper right of the star. The left quarter of the planet (the side facing the star) is lit, while the rest is in shadow. The planet has hints of a rocky, partly molten surface beneath the haze of a thin atmosphere. The boundary between the day and night sides of the planet is fuzzy.

NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet

Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.  Renyu Hu from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, is … Continue reading NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet
