Euclid space telescope

The Euclid space telescope is a European observatory launched to map the structure of the universe by observing billions of galaxies across 10 billion years of cosmic history. By measuring how galaxies are distributed in space and how the universe's expansion has accelerated over time, Euclid helps scientists understand the nature of mysterious dark matter and dark energy that make up most of the universe. Think of it as creating the largest 3D map of the cosmos ever made, revealing the invisible forces shaping everything we see.
