Atmospheric spectra of three hot Jupiters showing water absorption

This graph compares observations with modeled infrared spectra for three hot-Jupiter-class exoplanets. These exoplanets were spectroscopically observed with the NASA/ESA Hubble Space Telescope. The red curve in each case is the best-fit model spectrum for the detection of water vapor absorption in the planetary atmosphere. The blue circles and error bars show the processed and analysed data from Hubble's spectroscopic observations.
