NASA Telescopes Find Clear Skies and Water Vapor on Exoplanet

A Neptune-size planet with a clear atmosphere is shown crossing in front of its star in this artist’s depiction. Image credit: NASA/JPL-Caltech Astronomers using data from three of NASA’s space telescopes — Hubble, Spitzer and Kepler — have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system. The planet is about the size of Neptune, making it the smallest planet from which molecules of any kind have been detected. “This discovery is a significant milepost on the road to eventually analyzing the atmospheric composition of smaller, rocky planets more like Earth,” said John Grunsfeld,…
