Mapping one billion stars in our Galaxy may seem like an impossible feat, but that’s exactly what ESA’s Gaia mission aims to do, with the ultimate goal of creating the largest, most precise 3D map of our Galaxy ever made. And now you can follow the mission’s progress with a new app created by the University of Barcelona. Being able to track the progress of this groundbreaking mission via your iPhone, iPad or iPod available for free from the iTunes store in English, Spanish and Catalan.

Repeatedly scanning the sky, Gaia will observe each of its billion stars an average of 70 times each over five years. In addition to positions and motions, Gaia will also measure key physical properties of each star, including its brightness, temperature and chemical composition.

Located at the L2 Lagrange point, 1.5 million km from Earth, Gaia surveys the entire sky as it spins on its axis. By repeatedly measuring the positions of the stars with extraordinary accuracy, Gaia is providing a huge treasure trove of data that enables scientists to tease out their distances and motions through our Galaxy.
“More than 50 billion focal plane transits, 110 billion photometric observations and 9.4 billion spectroscopic observations have been successfully processed to date,” notes Fred Jansen, ESA’s mission manager for Gaia.
