The DES has completed its survey operations in 2019 and has imaged 5,000 square degrees of the night sky in 5 optical bands to a depth of i-mag ~24. The DES Collaboration is focussing on the science analyses of this exciting data set and will continously publish results in cosmology, galaxy formation, transients, Milky Way, and Solar System science over the coming years.


DES data provides an exciting opportunity to explore cosmic acceleration now and it is an ideal testing ground for the LSST analysis, in particular for LSST Year 1, which is comparable in depth to DES.
