On December 19, 2013, the Gaia space probe was launched from the European Space Port in Kourou, in French Guiana. He did it aboard a Soyuz launcher, and thus began an exciting mission to censor about a billion stars.
A much more accurate map of the Milky Way will be created through the Gaia mission. Gaia will accurately measure the position and displacement of 1 percent of the stars found in our galaxy. The data obtained will help to better understand the origin and evolution of a small part of our Universe.
The map of the stars that Gaia will generate will be three-dimensional and very precise. In addition, Gaia will map the movements of these stars, which will shed light on the origin and evolution of the Milky Way.
The photometric measurements made will provide data such as the physical properties of each star studied, and also its temperature, luminosity, gravitation and its composition in chemical elements. To obtain this data, Gaia will monitor each of the investigated stars about 70 times over a period of five years.
Thanks to the star census developed by the Gaia mission, a good number of quasars and galaxies, extrasolar planets and other bodies of the Solar System can be measured simultaneously.
