The European Space Agency unveiled a three-dimensional map of a billion stars in our galaxy that is 1,000 times more complete than anything existing today.

A space-based probe called Gaia, launched in December 2013, has been circling the Sun 1.5 million kilometres (nearly a million miles) beyond Earth's orbit and has been discreetly snapping pictures of the Milky Way.
