Lifting the veil on a dark galaxy

6 febrero 2015

A cluster of young, pulsating stars discovered in the far side of the Milky Way may mark the location of a previously unseen dark-matter dominated dwarf galaxy hidden behind clouds of dust. A team used data collected by the ESO’s VISTA to find four young stars approximately 300,000 light years away. These young stars are Cepheid variables, the most distant found close to the plane of the Milky Way.
