For decades people have been trying to explore the universe. GAIA, a space mission of the European Space Agency (ESA) launched in 2013 for the most xtensive survey of our galaxy to date.
With the GAIA space telescope, astronomers are able to take measurements of approximately one percent of all the stars in our Milky Way – an estimated one billion stars – with very high precision. Using these star measurements, researchers will create a three-dimensional map of the Milky Way. This map also contains the positions, distances and movements of the celestial bodies in space. These findings will help scientists clarify the origin of stars and the development of the Milky Way.
