Detection of water vapor in the atmosphere of a hot jupiter

Although liquid water covers a majority of Earth’s surface, scientists are still searching for planets outside of our solar system that contain water. Caltech researchers have used a new technique to analyze the atmospheres of such exoplanets, making the first detection of water in the atmosphere of the Jupiter-mass planet orbiting the nearby star tau Boötis. This technique could help researchers learn about how many planets with water — like Earth — exist within our galaxy.
