Gaia’s Map of 1.3 Billion Stars Makes for a Milky Way in a Bottle.

Call it a galaxy in a bottle.

Last Wednesday, astronomers in Europe released a three-dimensional map of the Milky Way. It is the most detailed survey ever produced of our home galaxy. It contains the vital statistics of some 1.3 billion stars — about one percent of the entire cosmic panoply of which Earth and the sun are part. Not to mention measurements of almost half a million quasars, asteroids and other flecks in the night.
