A European space telescope blasted off on Saturday to explore the mysterious dark universe. The European Space Agency’s Euclid observatory was launched by SpaceX and will travel 1 million miles away to the Webb Space Telescope’s neighborhood. After a month-long journey, Euclid will start a six-year survey this fall. Scientists hope Euclid’s observations will provide insights into the dark energy and dark matter that make up most of the universe. Euclid will measure dark energy and dark matter with unprecedented precision. The telescope’s 3D map of the cosmos will help explain the evolution and expansion of the dark universe.
