The interacting pair of galaxies M51 (bottom) and NGC 5194 (top) as viewed through ESASky, ESA's interactive portal to access astronomical data from space science missions. The green squares are footprints on the sky of different instruments on board the NASA/ESA Hubble Space telescope.
ESASky is a discovery portal that provides full access to the entire sky. The open-science application contains over half a million images, 300 000 spectra and more than one billion catalogue sources.
ESASky features an easy-to-use interface to explore, visualise and download science-ready data from any position in the sky by zooming and panning.
