VISTA finds hidden feature of Milky Way

Astronomers using the VISTA telescope at ESO’s Paranal Observatory have discovered a previously unknown component of the Milky Way. By mapping out the locations of a class of stars that vary in brightness called Cepheids, a disc of young stars buried behind thick dust clouds in the central bulge has been found.

This video shows the locations of the newly discovered Cepheids (red dots) in an artist’s rendering of the Milky Way.
