Gaia Space Observatory

The Gaia Space Observatory is a spacecraft launched by the European Space Agency to create a detailed 3D map of our galaxy, the Milky Way. It precisely measures the positions, distances, and motions of over a billion stars, allowing scientists to understand the galaxy’s structure, formation, and evolution. Gaia's data also helps identify star clusters, exoplanets, and provides insights into dark matter and cosmic history. Operating from space avoids atmospheric distortion, enabling unprecedented accuracy in charting the universe. Its mission enhances our knowledge of the universe's composition and dynamics on a grand scale.
