ESO press releases describe scientific, technical and organisational developments and achievements and results obtained by scientists with ESO facilities. The organisation publishes three types of press releases. Science releases describe results (usually appearing in a peer-reviewed journal) involving data from ESO observatories or staff. Organisational releases cover a range of themes related to ESO operations, including news on current and future observatories, new astronomical instruments and announcements of exhibitions worldwide. ESO also selects its best astronomical images, and presents them publicly in periodic photo releases. All press releases (dating back to 1985) are available online. There are child-friendly versions and press releases translated into the languages of ESO's member countries.
