Digital Access to a Sky Century @ Harvard (DASCH) is a unique project at the Harvard College Observatory that aims to digitize the majority of the Astronomical Photographic Plate Collection's 500,000 glass plate negatives and produce full photometry results for the entire sky. The DASCH project is uniquely designed for Time Domain Astronomy/Astrophysics, which is one of the most prioritized fields of study in astrophysics today. The stars photographed on glass plates between 1880s-1990s operate as time capsules, allowing astronomers to study how the sky has changed over one hundred years.
