With the goal of simplifying the access to science data to scientists and
citizens, ESA recently released ESASky (http://sky.esa.int), a new open-science
easy-to-use portal with the science-ready Astronomy data from ESA and other
major data providers. In this presentation, we announced version 2.0 of the
application, which includes access to all science-ready images, catalogues and
spectra, a feature to help planning of future JWST observations, the
possibility to search for data of all (targeted and serendipitously observed)
Solar System Objects in Astronomy images, a first support to mobile devices and
several other smaller usability features. We also discussed the future
evolution of the portal and the lessons learnt from the 1+ year of operations
from the point of view of access, visualization and manipulation of big
datasets (all sky maps, also called HiPS) and large catalogues (like e.g. the
Gaia DR1 catalogues or the Hubble Source Catalogue) and the design and
validation principles for the development of friendly GUIs for thin layer web
clients aimed at scientists.Comment: 4 pages, 2 figures, ADASS 2017 conference proceeding
