ESA Science & Technology - An all-inclusive astronomical atlas

All-sky view of the content of ESASky, ESA's interactive portal to access astronomical data from space science missions.

By zooming out to see half of the sky and displaying the footprints from all the missions (visualised as squared in different colours), the users get a coverage map of all observations ever done from the X-ray to the far-infrared in one single map.

ESASky is a discovery portal that provides full access to the entire sky. The open-science application contains a universe of data – over half a million images, 300 000 spectra and more than one billion catalogue sources.
