NASA’s Webb Maps Weather on Planet 280 Light-Years Away
By Space Telescope Science Insitute An international team of researchers has successfully used NASA’s James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b. Precise brightness measurements over a broad spectrum of mid-infrared light, combined with 3D climate models and previous observations from other telescopes, suggest the presence of thick, […]
NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere
Astronomers using NASA’s Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. “This would be the first time that we can directly show through […]
