Unlocking the secrets of the cosmos, venturing into the unknown, and shining light on the mysteries that lie beyond welcome back, space lovers. Today, we start on an extraordinary journey with ESA's groundbreaking mission, Euclid, as we discover the dark side of the universe. ESA's Euclid mission is meant to bring the dark side of the universe to light. You see, astronomers have long suspected that two unseen entities rule the composition of our cosmos, dark matter and dark energy, yet directly spotting these enigmatic forces has eluded us. Based on the way galaxies rotate and orbit one another, and the way in which the universe is expanding, scientists have inferred the presence of dark matter and dark energy. However, it's time to delve deeper and gain a more thorough understanding of these cosmic enigmas. Enter Euclid, the project that will revolutionize our understanding of the universe. This incredible spacecraft will build a 3D map of the cosmos, with time itself as the third dimension. By watching billions of galaxies, some located up to 10 billion light years away, Euclid will unlock the secrets hidden within the fabric of space and time. Scientists will chart the position and velocity of galaxies over immense distances, drawing a vivid picture of cosmic history. The further away, a galaxy is located, the longer its light has taken to reach us, showing the earlier stages of the universe. Through Euclid's extraordinary optics, we will discover subtle distortions in the appearance of galaxies, giving crucial clues about the nature of dark matter and dark energy. From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter with unparalleled accuracy. This will be a major leap forward in our understanding of the universe, allowing theorists to refine their models and unravel the mysteries that have perplexed us for so long. The secrets of the universe await, and Euclid is our path to unlocking them. Join us on this cosmic adventure as we witness the birth of new knowledge, showing the true nature of our vast universe.
