In July, the European Space Agency (ESA) initiated the Euclid telescope’s cosmic expedition, positioning it a remarkable 1 million miles from Earth. This groundbreaking venture aims to unravel the universe’s mysteries through a detailed 3D map of its hidden “dark side.” Euclid’s distinguishing feature is its vast perspective, spanning an area 100 times broader than NASA’s James Webb Space Telescope. The telescope recently shared its inaugural images, showcasing stellar nurseries, expansive galaxy clusters, and distant stars, providing an unprecedented glimpse into cosmic landscapes.

In its cosmic journey, Euclid explored the Perseus Cluster, located 240 million light-years away, and delved into the secrets of the Hidden Galaxy, IC 342, veiled in dust and gas. Euclid’s precision also scrutinized NGC 6822, an irregular dwarf galaxy from the universe’s early days, revealing intricate details about these celestial enigmas. Named after the ancient Greek mathematician Euclid, he embarks on a six-year mission to survey one-third of the celestial sphere. Using its NISP tool, Euclid captures stunning color images, such as the Horsehead Nebula, 1,375 light-years away. This advanced instrument enables Euclid to surpass the achievements of the Hubble Space Telescope, covering more celestial ground in days than Hubble has in its entire existence. Euclid’s ultimate aim is to craft the most extensive 3D map, offering unparalleled insights into the intricate evolution and composition of the vast cosmic tapestry.
