The European Space Agency successfully put its Gaia satellite into orbit, with the hopes of unrolling a stunning map of the Milky Way in 3D.

The Milky Way is about to be seen in a whole new way.
The European Space Agency has successfully launched its Gaia satellite into orbit, bringing a 1 billion-pixel camera detector to map our galaxy in 3D.
The stargazer lifted off on Thursday aboard a Soyuz-Fregat rocket from a launch pad at Sinnamary in French Guiana. Its mission is to map the precise location of over a billion stars.
Its instruments are expected to help discover planets, asteroids, and supernovas, as well as reveal a better understanding of the origin and structure of the Milky Way.

Yea I heard about this too, sounds amazing!

Btw does Gaia make MW@H 3D mapping obsolete?

My quick take would be that it makes MW@H more relevant than ever. The Sloan Digital Sky Survey that they currently use is massive and nice but I imagine this will trump it by over an order of magnitude. The base data will be similar (star positions and magnitudes), just more. So, the algorithms and processing flow the fine folks at RPI have pioneered here would probably be the only tractable means for processing this new data set.
