earth atFor the first time, gas was detected in the atmosphere of a super-Earth. Using the Wide Field Camera (WFC3) technology on the Hubble Space Telescope, astronomers found a significant amount of hydrogen and helium on 55 Cancri e, 40 light years away. However, no water vapor was found, making it a dry exoplanet.
