Welcome to the ST-ECF Hubble Science Data Archive

The following pages, maintained by the Space Telescope – European Coordinating Facility (ST-ECF), provide access to the ST-ECF Science Data Archive, a European copy of the Hubble Space Telescope science data. The ST-ECF archive is the result of a very fruitful and continuous collaboration with the Space Telescope Science Institute (STScI) the Canadian Astronomy Data Centre (CADC), and the European Organisation for Astronomical Research in the Southern Hemisphere (ESO) .

The ST-ECF main archive can be directly accessed through the HST Science Archive Queries item in the navigation menu; further, more specialized query interfaces are also available in a dedicated page.

Through the years, the ST-ECF has been instrumental in the development of many archive value added products, available in the Public Data Products page. Within this framework, as a recent development, all three Hubble archives (STScI, CADC, and ST-ECF) have coordinated their efforts to optimize the future return from their archives. This project, the Hubble Legacy Archive (HLA), offers enhanced data products and new methods of data discovery and access.
