Exoplanets evaluated in new light
Berlin, Germany (SPX) Apr 12, 2024 Located 700 light years from Earth in the Virgo constellation, the exoplanet WASP-39b, which completes its orbit around the star WASP-39 in just over four days, has been under the close scrutiny of NASA's James Webb Space Telescope since its commissioning in July 2022. Early observations revealed the presence of water vapor, methane, and, for the first time on any exoplanet, carbon dioxide in WASP-39b's atmosphere. This discovery, while significant, also highlighted discrepancies in the modeling of thes ... read more |

More Planets than Stars: Kepler's Legacy
Washington DC (SPX) Mar 07, 2024 The Kepler mission enabled the discovery of thousands of exoplanets, revealing a deep truth about our place in the cosmos: there are more planets than stars in the Milky Way galaxy. The road to this fundamental change in our understanding of the universe, however, required almost 20 years of persistence before the mission became a reality with its selection in 2001. Astronomers had assumed, but still had not confirmed, the existence of exoplanets when the mission concept that would become Kepler w ... read more
