Euclid, the #DarkUniverse detective🕵️, will map the Universe by observing billions of galaxies out to ten billion light-years over one third of the sky to study dark matter and dark energy.After a flawless launch, Euclid set path to orbit L2 where it joined @ESA_Webb and @ESAGaia to peer into the Universe side by side.Despite some initial obstacles, Euclid has already shown its ability to capture the cosmos in two stunning image releases. 🔗https://www.esa.Euclid_s_first_images_the_dazzling_edge_of_darkness🔗https://www.esa.ESA_s_Euclid_celebrates_first_science_with_sparkling_cosmic_viewsBut what obstacles did Euclid have to overcome?Obstacle one: the Sun☀️After launch, Euclid's first data showed that a minuscule amount of sunlight had crept into its extremely sensitive VIS instrument.However, by avoiding certain angles, the #DarkUniverse detective🕵️could continue its observations, thanks to a team effort to redesign the survey. 🔗https://www.esa.Seeking_Euclid_s_hidden_stars_commissioning_looks_upObstacle two: lost guide stars💾Cosmic rays confused Euclid's tracking software, which tells where the spacecraft is pointed and keeps it stabilised🛜An update was sent up, allowing the #DarkUniverse detective🕵️ to stargaze once again🔗https://www.esa.Guide_stars_found_as_Euclid_s_navigation_fine_tunedObstacle three: ice❄️During its time in space, a very thin layer of water ice formed on some of Euclid's optics.@esaoperationsheated some mirrors and removed the ice, a procedure which has become part of Euclid’s normal operations.🔗https://esa.Operations_begin_to_de-ice_Euclid_s_visionEuclid started its science survey on 14 February and has already covered 883 square degrees of our extragalactic sky.🔗https://esa.Euclid_begins_its_dark_Universe_surveyMore cosmic views to follow in the coming years, revealing more about the secrets of the dark Universe ✨
