Aladin Desktop allows the user to view archival sky atlases, astronomical images, surveys, and more.

It is comprehensive, with 20 000+ data collections (DSS, SDSS, PanSTARRS, Skymapper, Gaia, Simbad, NED, VizieR, etc.). Aladin is provided as an interactive sky atlas software allowing the user to visualize digitized astronomical images, superimpose entries from astronomical catalogs or databases, and interactively access related data and information from the Simbad database, VizieR service, and other archives for all known sources in the field.

Created in 1999, Aladin has become a widely-used VO tool capable of addressing challenges such as locating data of interest, accessing and exploring distributed datasets, visualizing multi-wavelength data. Compliance with existing or emerging VO standards, interconnection with other visualization or analysis tools, ability to easily compare heterogeneous data are key topics allowing Aladin to be a powerful data exploration and integration tool and a science enabler.
