An international team of astronomers has mapped the movement of stars in the Milky Way - a move which could improve understanding of our galaxy.
A 3-D map of how stars move in the general rotation of our galaxy took the scientists 15 years to build and will be published in the journal Astronomy & Astrophysics.
The results of the study by the Danish, Swiss and Swedish team included more than 1000 nights of observing more than 14,000 Sun-like stars, the so called F- and G-stars.
