ViaLactea is a toolkit of visual analytics interfaces for the Astrophysics and Planetary sectors facilitating exploitation of multi-wavelength (from near infrared to the radio spectrum) observations of the Milky Way [VSB+18].

The underlying ecosystem is strongly driven by FAIR principles and Open Science practices and is integrated within the European Open Science Cloud (EOSC). ViaLacteaWeb (VLW) is a recently developed toolkit component for an integrated web solution for cloud-based visualisation functionality. The aim is to provide a testbed for realising remote and interactive correlation analysis workflows to study star formation processes in the Milky Way. VLW sports a rich web UI supporting multiple user scenarios exploiting a remote knowledge database that provides object catalogues and spectral energy distribution model outputs (VLKB). The overall performance is limited only by the remote visualisation scalability capacity of the underlying infrastructure and it can be CPU and/or GPU based. VLW is accessed via a dedicated client running in common web browsers and is based on specific VLKB queries to perform sophisticated interactive visualisation operations remotely.
