The European Space Agency announced it will launch its Gaia mission on . What’s Gaia’s goal? To create a highly accurate 3D map of the Milky Way like never before. The spacecraft sports two telescopes that feed into a nearly billion-pixel digital camera-the largest camera ever flown in space. Gaia will be observing a billion stars to determine their positions in space and their movement through it. It will also use additional instruments to access certain star properties such as temperature, luminosity, and composition. This info will allow astronomers to determine the origin and evolution of the Milky Way Galaxy. The story is in the stars--that sounds nice. ESA says they’re anxiously going through their final checklist and getting ready for the launch.
