Gaia: Gaia's surprising discoveries: From the Sun's neighbourhood to the distant Universe

Gaia news - Sat, 2018-04-21 01:27
Gaia's first data release was not designed to be a full database with which major scientific discoveries could be made. Instead it was foreseen much more as a set of test data that astronomers could practice on and get ready for the second release from ESA's billion-star surveyor – the one that would feature a billion parallaxes and proper motions of stars.
