The Gaia mission is tracking a billion stars


Today’s Video of the Day from the European Space Agency describes the Gaia mission, which was launched in 2013 in an effort to observe over a billion stars across the Milky Way galaxy.

The movement in the positions of these stars will be measured with unprecedented accuracy, providing scientists with new details about stellar systems.

A data release from 2016 has already informed hundreds of scientific studies, as the mission continues to reveal new secrets about our Universe.
