Gaia second data release

The second data release of ESA’s Gaia mission has produced an extraordinary catalogue of over one and a half billion stars in our galaxy. Based on observations between July 2014 to May 2016, it includes the most accurate information yet on the positions, brightness, distance, motion, colour and temperature of stars in the Milky Way as well as information on asteroids and quasars. ★ Subscribe: http://bit.ly/ESAsubscribe Learn more: http://bit.ly/GaiaRickestStarMap
