VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a major observatory for gamma-ray astronomy in the 100 GeV-50 TeV energy band. The observatory, located on Mt. Hopkins, AZ, consists of four 12 m-diameter telescopes that detect very high-energy gamma rays via the imaging atmospheric Cherenkov technique. VERITAS became fully operational in Spring 2007 and has embarked on a broad program of observations of galactic and extragalactic sources. I will summarize the major results from the observatory, concentrating on observations of X-ray binaries and extragalactic blazars.
