Pinpointing Gaia to Map the Milky Way

Caption

This image, a composite of several observations captured by ESO's VLT Survey Telescope (VST), shows the space observatory Gaia as a faint trail of dots across the lower half of the star-filled field of view. These observations were taken as part of an ongoing collaborative effort to measure Gaia's orbit and improve the accuracy of its unprecedented star map.
