![]() ![]() N ISP is a near infrared (NIR) camera that does double duty as a photometer (YJH) and a spectrometer (three 1.25-1.85 microns red grisms and one 0.92-1.3 micron blue grism, 0.55 sq deg FoV, 0.3 arcsec pixels, R~380 for 0.5 arcsec radius objects). VIS is an optical camera for photometry (550-900nm, 0.56 sq deg FoV, 0.1 arcsec pixels). Euclid consists of a 1.2m space telescope with two instruments: VIS and NISP. The launch is planned for July to September 2023.Įuclid will map the large-scale structure of the Universe with photometry and spectroscopy over approximately 15,000 square degrees of the extragalactic sky - or nearly half of the full sky excluding the regions dominated by the stars in our Milky Way galaxy. ![]() ![]() On October 20, 2022, the official ESA feed of the Euclid mission, tweeted: “Few hours ago the ESA Council made the decision about the launcher: ESA’s proposal to use the SpaceX vehicle Falcon 9 was approved for a launch in 2023” (click here to see the original tweet). The Euclid mission will investigate dark energy, the unknown cause of the accelerating expansion of the Universe, as well as dark matter, invisible but holding cosmic large-scale structure together with its gravity. ![]()
