SUMMARY: The European Space Agency is working an ambitious new space observatory that will be capable of precisely mapping a billion stars in our galaxy. Called Gaia, the spacecraft will launch in 2010 and observe the sky for a period of five years. Astronomers will compile this detail into a 3D map of a billion stars, including their position, motion and even composition. With such a comprehensive map of the sky, Gaia will turn up all kinds of new objects, and give astronomers plenty of future targets to study with more sensitive instruments.
