The ESO Science Archive is a powerful scientific resource for the entire astronomical community, contributing to about 40% of the overall ESO science output as quantified by refereed papers. It stores both the raw data generated by all ESO instruments, as well as selected processed data. These come from ESO public surveys, large programmes and from bulk processing of selected instruments. They are processed to a level where can be used directly for scientific measurements. An added service is also browsing and retrieval of ALMA data, conjointly with those of La Silla-Paranal Observatory. User access services and capabilities are provided to make this rich content discoverable to the science community in the face of the ever increasing volume and complexity of the archive holdings. In this presentation, the capabilities, archive user services, the diversified data holding and user community statistics, including scientific publications, of the ESO Science Archive are briefly illustrated. It highlights the legacy of the ESO archive as a resource in support of future multi-wavelength multi-messenger time-domain investigations of the Southern Sky. |
