Euclid observar\u00e1 miles de millones de galaxias a 10 mil millones de a\u00f1os luz para crear el mapa 3D m\u00e1s grande y preciso del Universo, con la tercera dimensi\u00f3n representando el

representing time itself.<\/p>\n<p>This detailed chart of the shape, position and movement of galaxies will reveal how matter is distributed across immense distances and how the expansion of the Universe has evolved over cosmic history, enabling astronomers to infer the properties of dark energy and dark matter.<\/p>\n<p>This will help theorists to improve our understanding of the role of gravity and pin down the nature of these enigmatic entities.<\/p>\n<p>To achieve its ambitious scientific goal, Euclid is equipped with a 1.2-m reflecting telescope that feeds the two innovative scientific instruments: VIS, which takes very sharp images of galaxies over a large fraction of the sky, and NISP, which can analyse galaxies\u2019 infrared light by wavelength to accurately establish their distance.<\/p>\n<p><iframe loading=\"lazy\" title=\"Euclid | Lift-off\" src=\"https:\/\/www.youtube.com\/embed\/S_oJcqXty4c\" width=\"580\" height=\"326\" frameborder=\"0\"

data Euclid will acquire, ESA\u2019s Estrack network of deep space antennas has been upgraded.<\/p>\n<p>\u201cThe successful launch of Euclid marks the beginning of a new scientific endeavour to help us answer one of the most compelling questions of modern science,\u201d said ESA Director General Josef Aschbacher.<\/p>\n<p>\u201cEuclid has been made possible by ESA\u2019s leadership, the effort and expertise of hundreds of European industrial and scientific institutions, and through collaboration with international partners.\u201d<\/p>\n<p>\u201cThe quest to answer fundamental questions about our cosmos is what makes us human.\u201d<\/p>\n<p>\u201cAnd, often, it is what drives the progress of science and the development of powerful, far-reaching, new technologies.\u201d<\/p>\n<p>\u201cESA is committed to expanding Europe\u2019s ambitions and successes in space for future generations.\u201d<\/p>\n<p>\u201cThe Euclid mission is the result of the passion and expertise of those who contributed to designing and building this sophisticated space telescope, the competence of our flight operations team, and the inquiring spirit of the science community,\u201d said Euclid project manager Giuseppe Racca, a researcher with ESA.<\/p>\n<p>\u201cThere have been many challenges during the project, but we have worked hard and now we have successfully reached this launch milestone together with our partners in the Euclid Consortium and NASA.\u201d<\/p>\n<p>\u201cWe are thrilled about the successful launch of ESA\u2019s Euclid mission and are eager to see the science it returns,\u201d said Nicola Fox, associate administrator for NASA\u2019s Science Mission Directorate.<\/p>\n<p>\u201cBy studying the \u2018dark side\u2019 of our Universe, Euclid is not only paving the way for NASA\u2019s Roman Space Telescope, it is igniting a new golden age of survey astronomy that will help us understand our Universe\u2019s history and structure in ways that were not possible before.\u201d<\/p>\n<p>\u201cToday we celebrate the successful launch of a ground-breaking mission that places Europe at the forefront of cosmological studies,\u201d said Carole Mundell, ESA\u2019s Director of Science.<\/p>\n<p>\u201cIf we want to understand the Universe we live in, we need to uncover the nature of dark matter and dark energy and understand the role they played in shaping our cosmos.\u201d<\/p>\n<p>\u201cTo address these fundamental questions, Euclid will deliver the most detailed map of the extragalactic sky.\u201d<\/p>\n<p>\u201cThis inestimable wealth of data will also enable the scientific community to investigate many other aspects of astronomy, for many years to come.\u201d<\/p>\n<p>\u201cThis is a great moment for science, one that we have long been looking forward to: the launch of Euclid, on a mission to decipher the puzzle of dark matter and dark energy,\u201d said Euclid project scientist Ren\u00e9 Laureijs, a researcher with ESA.<\/p>\n<p>\u201cThe big mystery of the fundamental constituents of the Universe is staring us in the face, offering a formidable challenge.\u201d<\/p>\n<p>\u201cThanks to its advanced telescope and powerful scientific instrumentation, Euclid is poised to help us unravel this mystery.\u201d<\/p>\n<p>In the next four weeks, Euclid will travel towards Sun-Earth Lagrange point 2, an equilibrium point of the Sun-Earth system located 1.5 million km from Earth (about four times the Earth-Moon distance) in the direction opposite from the Sun.<\/p>\n<p>There, Euclid will be manoeuvred into orbit around this point and mission controllers will start the activities to verify all the functions of the spacecraft, check out the telescope and finally turn on the scientific instruments.<\/p>\n<p>Scientists and engineers will then be engaged in an intense two-month phase of testing and calibrating Euclid\u2019s scientific instruments and preparing for routine observations.<\/p>\n<p>Over six years Euclid will survey one third of the sky with unprecedented accuracy and sensitivity.<\/p>\n<p><strong>Fuente:<\/strong> <a
