ESASky is a science-driven discovery portal providing full access to the entire sky as observed with all ESA Space astronomy missions. This service provides access to catalogues, observations, and spectra hosted at the ESAC Science Data Centre.
Science images from the HST and HLA collections hosted at ESAC/ESA. All public HST observations in calibrated and science-ready form are synchronised with the MAST services for HST reprocessed public data and corresponding metadata. The European HST archive interface can be accessed at https://hst.esac.esa.int/ehst
This service provides access to tables and catalogues of the ISO ESA mission.
The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths. The two spectrometers (SWS and LWS), a camera (ISOCAM) and an imaging photo-polarimeter (ISOPHOT) jointly covered wavelengths from 2.5 to around 240 microns with spatial resolutions ranging from 1.5 arcseconds (at the shortest wavelengths) to 90 arcseconds (at the longer wavelengths). Its 60 cm diameter telescope was cooled by superfluid liquid helium to temperatures of 2-4 K.
