National and International Facilities
Yale astronomers are routinely awarded time on NASA and ESA space-based telescopes, including the Hubble Space Telescope, Kepler, the X-ray telescopes CHANDRA and RXTE, the infrared Spitzer and Herschel telescopes, and the gamma-ray telescope Fermi. There is significant scientific synergy between these space-based missions and Yale's ground-based telescopes. In addition, Yale astronomers frequently utilize the facilities available at the national and international optical and radio observatories, including Kitt Peak, Gemini, ALMA and Arecibo.
