| The properties of worlds orbiting other stars are now accessible to us, using the Spitzer and Hubble Space Telescopes. Many exoplanets emit strongly in the infrared, and Spitzer has directly measured this infrared light for the class of transiting extrasolar planets. Cryogenic Spitzer investigations have produced orbital phase curves, a temperature map, and spectra of "hot Jupiter" exoplanets, as well as measurement of thermal emission from a Neptune-sized planet orbiting the M-dwarf GJ436. Future studies using the James Webb Space Telescope will measure spectral features from the atmosphere of a habitable planet orbiting a nearby M-dwarf star. |
