Incredible!
(Yeah - that "just happened". Palease...
)
An earlier star-mapping ESA mission called Hipparcos—launched in 1989 and concluded a few years later—recorded about 118,000 stars at distances of 300 light years.

3D Map Of The Galaxy
Even with the vast scope of this mission—mapping a billion stars over five years—Gaia is only scratching the surface of what’s out there. The Milky Way contains more than 100 billion stars.
The satellite will record the position, brightness, and color of every “celestial object” within view. In fact, it will measure them repeatedly. That way, astronomers will be able to calculate the distance, speed, and direction of motion of the objects and chart variations in their brightness.
