Gaia spacecraft

The Gaia spacecraft, launched by the European Space Agency, is an observatory designed to create the most detailed 3D map of our galaxy, the Milky Way. It measures the positions, distances, and movements of over a billion stars with extraordinary precision. By doing so, Gaia helps scientists understand the history, structure, and evolution of our galaxy. Using advanced instruments and precise measurements, Gaia’s data also contribute to studying dark matter, star formation, and the universe’s overall dynamics, providing insights into the cosmos that were previously unimaginable.
