Water That’s Out Of This World Detected By Hubble

NASA announced that the Hubble Telescope has identified five alien worlds that have subtle traces of water. Signals may be faint but it’s there, say researchers. These five planets orbit nearby stars and are all hot Jupiters, meaning they orbit close to their host stars. All the planets were hazy making the atmospheres difficult to detect. But, using Hubble’s Wide Field Camera 3, the scientists were able to make observations in a range of infrared wavelengths where the water signature would appear. They compared shapes and intensities of the absorption profiles, and the consistency of the signatures confirmed that they did see water.
