Observations of the secondary eclipse of an exoplanet, the moment the planet moves behind its star, allow us measure the radiation emitted by the exoplanet. These measurements enable us to determine atmospheric properties like the temperature and energy redistribution. In this talk I will present our exciting new results from optical and Near-Infrared observations of the day-side emission from exoplanets. Our secondary eclipse measurements in K-band have resulted in the detection of thermal emission from TrES-3b, and our analysis of CoRoT data show the optical phase curve of an exoplanet for the first time.
