Scientists can mine the dataset to determine the distances to individual galaxies and place them into the 3D structure of the Universe, connecting them to the vast, invisible mesh of the cosmic web. This distance-measuring and mapping is something Euclid does via spectroscopy\u2014by splitting the light from galaxies into \u2018rainbows\u2019 that tell us about their distance (and for especially bright ones, their origin and composition too).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While enormous, the dataset only covers about 14% of the total sky area Euclid will survey. The full Data Release 1, to come in mid-2027, will build on today\u2019s release and add more crucial parts to the cosmic puzzle, including observations of weak lensing to complement the strong ones, and calculations of how galaxies and galaxy clusters fit into the cosmic web.<\/span><\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text module_class=&#8221;section-title&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; header_2_font=&#8221;|700|||||||&#8221; header_2_font_size=&#8221;25px&#8221; hover_enabled=&#8221;0&#8243; header_2_font_size_tablet=&#8221;23px&#8221; header_2_font_size_phone=&#8221;23px&#8221; header_2_font_size_last_edited=&#8221;on|phone&#8221; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h2>The Spanish contribution to Euclid<\/h2>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; link_font=&#8221;|700|||on||||&#8221; hover_enabled=&#8221;0&#8243; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<p><span style=\"font-weight: 400;\">Euclid has a 1.2 metre diameter telescope and two instruments on board: VIS (VISible instrument) and NISP (Near-Infrared Spectrometer and Photometer).
