Exoplanet atmospheres detected from earth

Two independent groups have simultaneously made the first-ever ground-based detection of extrasolar planets thermal emissions. Until now, virtually everything known about atmospheres of planets orbiting other stars in the Milky Way has come from space-based observations. These new results, accepted for publication in Astronomy and Astrophysics, open a new frontier to studying these alien worlds and are especially critical because the major space-based workhorse to these studies, the Spitzer telescope, will soon run out of cryogens, highly limiting its capabilities...
