Hubble Space Telescope/Chandra X-ray Observatory
Image of Cheshire Cat gravitationally lensed galaxies
Image of Cheshire Cat gravitationally lensed galaxies produced by combining Chandra X-ray data with Hubble Space Telescope optical data. Gemini spectroscopy provided critical spectroscopic data for characterizing the foreground lensing cluster and understanding its history and likely fate as a "fossil group."
