The Most Detailed Map of the Milky Way Ever Made | Gaia Mission #MilkyWay #GaiaMission Using data from the European Space Agency’s Gaia mission, astronomers have created the most precise map of the Milky Way ever produced. Built from nearly three trillion observations of about two billion stars over more than a decade, this data-rich 3D map reveals stellar positions, distances, motions, and hidden structures across our galaxy. Gaia’s map exposes spiral arms, star clusters, stellar streams, and p

Unveiling the Uncharted Milky Way • Completing the Galactic Stellar Map 12.4.25 VIDEO: Reconstruction of the Milky Way based on stellar orbits observed by the APOGEE survey. The colours of the stars approximately represent their ages, with red-yellow indicating older stars and green-blue representing younger stars. The light of all stars along the line of sight was combined, similar to the light observed with telescopes. Highlighted orbits of selected stars illustrate their paths within the Milk
