Science Archive Facility
ESO/ST-ECF Science Archive
The ESO/ST-ECF Science Archive Facility is a joint collaboration of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO) and the Space Telescope - European Coordinating Facility (ST-ECF).
The ESO Archive
The ESO Archive contains all observations performed at the La Silla Paranal Observatory on the NTT, MPG-ESO 2.2m, ESO 3.6m, VLT/VLTI and APEX telescopes.To browse the contents of the ESO archive, use the main ESO archive query form.
Following the agreement between ESO and the United Kingdom, the raw data from the UKIRT Infrared Deep Sky Survey (UKIDSS) taken with the Wide Field Infrared Camera (WFCAM) are also available through the main Archive query form to the astronomers from the ESO Member States. Reduced data are accessible here.
In addition, the ESO Archive holds various products: data from commissioning and science verification phases, ESO Imaging Survey and other projects, as well as Advanced Data Products.
Except for a few special cases, ESO data are world-wide available and can be requested after the usual one year proprietary period. Please read the official ESO Data Access Policy.
The HST Archive
The ST-ECF maintains the European copy of the Hubble Space Telescope Archive. The ST-ECF Archive is the result of a continuous collaboration with the Space Telescope Science Institute (STScI), the Canadian Astronomy Data Centre> (CADC), and the ESO's Data Management & Operations Division.In addition to the standard Hubble data, the ST-ECF archive also includes data products associated with special Hubble observing programs (such as the Hubble Ultra Deep Field, the HST/ACS GOODS Treasury Program, and the Hubble Deep Fields). In the near future, the ST-ECF will also release data associated to the Hubble Legacy Archive project (HLA), which will be initially focused to NICMOS grism observations. Similarly to ESO data, Hubble data can be retrieved without any restriction after the one-year proprietary period.
