The ‘Euclid’ space telescope detects 900 million galaxies and begins the three-dimensional map of the universe

The Euclid space telescope has detected 900 million galaxies, marking a significant step in mapping the universe. Launched on July 1, 2023, it aims to answer fundamental questions about the cosmos. The telescope's findings, covering an area equivalent to 9,500 full moons, are considered historic by scientists. Euclid utilizes gravitational lensing to observe light from galaxies that emitted it 10 billion years ago, helping to explore dark energy and dark matter, which make up most of the universe. Researchers believe Euclid will revolutionize our understanding of these cosmic mysteries.
