The James Webb Space Telescope (JWST) is currently the major space science observatory after a successful launch and commissioning phase. The ESAC Science Data Centre (ESDC) has been in charge of providing a European JWST Science Archive (eJWST) with the aim of boosting the science return of this great observatory. Within the established partnership of NASA, ESA and CSA, all JWST metadata and public data is being synchronised in near real time mirroring the Mikulski Archive for Space Telescopes (MAST) JWST archive at the Space Telescope Science Institute (STScI). The ESDC provides a carefully designed graphical user interface plus several backend services based on Virtual Observatory (VO) protocols to access both private (data stored at STScI) and public observations (data also stored at ESDC).

In this demo we will show how eJWST enables a quick, straightforward and user-friendly access to Webb’s data. We will explore the sky putting JWST observations data and metadata in the context of multi-wavelength science with the integration of the ESASky tool. Quick preview of data is also possible by means of archive data viewers.

We will also illustrate how the eJWST Archive provides several means to accelerate science by providing users access with searches based on the ADQL query language and dedicated python modules in packages such as an eJWST-specific Astroquery module. This package is included in the JWST area in ESA Datalabs, the new science exploitation platform developed by the Data Science and Archives Division at ESAC. A tour of the analysis, on-line processing and collaborative research that this platform offers will also be demonstrated.
