ESA’s Euclid mission sets out to decipher the enigma of dark matter and dark energy, utilizing its exceptional optics to observe billions of galaxies and construct a 3D time-map of the Universe. Through meticulous analysis of the collected data, scientists will gain valuable insights into these elusive entities, advancing our comprehension of the Universe’s expansion and the behavior of gravity on vast scales.
The European Space Agency’s Euclid mission strives to illuminate the concealed aspects of the Universe. Based on observations of galaxy rotations, orbital patterns, and the expansion of the Universe, astronomers infer the existence of two dominant yet unseen components: dark matter and dark energy. However, direct detection of these perplexing elements remains elusive, necessitating a mission capable of closely examining their influence on galaxies, galaxy clusters, and the Universe’s expansion itself. Euclid emerges as the answer to this imperative.
ESA’s Euclid mission aspires to unravel the properties and effects of the enigmatic dark matter and dark energy, which are believed to govern the composition of the Universe but have eluded direct detection. By observing billions of galaxies located up to 10 billion light-years away, Euclid will construct a comprehensive 3D map of the Universe, incorporating time as the third dimension. This extensive mapping endeavor will enable scientists to chart the positions and velocities of galaxies across immense cosmic distances and unveil the dynamics of the Universe’s expansion throughout its history.

With Euclid, ESA’s mission will materialize a 3D map of the Universe, where time plays the role of the third dimension. Galaxies positioned farther away require more time for their light to reach us, offering a glimpse into earlier cosmic epochs. By observing billions of galaxies spanning a distance of 10 billion light-years, scientists will meticulously trace the position and velocity of galaxies across colossal cosmic scales and vast stretches of time. In addition, Euclid’s remarkable optics will uncover subtle distortions in the appearance of galaxies.
Armed with this wealth of new data, astronomers will refine their understanding of dark energy and dark matter, unraveling their properties with unprecedented precision. This pivotal knowledge will aid theorists in comprehending the nature of these enigmatic components and achieving a more nuanced understanding of gravity’s behavior at the largest scales.
