Resumo: The Dark Energy Survey is currently conducting a multi-band imaging survey designed to study the nature of dark energy and help determine the cause of the accelerating expansion of the Universe. The survey consists of a Wide 5000 deg2 survey aimed to study galaxy clustering and weak gravitational lensing and a Deep 30 deg2 supernova survey designed to discover thousands of high-redshift Type Ia supernovae. Although the main goal of the survey is to study dark energy, the data also allow us to search for transient astronomical objects including minor bodies in the Solar System, peculiar stellar explosions, optical counterparts of gravitational-wave emitters, and other rare events. I will describe how we do this in both the Wide and Deep data and discuss some of the interesting transients we have discovered.
