Astronomy & Astrophysics published the first analysis of a catalog of 84 million individual stars in the Milky Way bulge as a part of the VVV (VISTA Variables in the Via Lactea) ESO public survey. This gigantic data set allows building the largest, deepest, and most accurate color-magnitude diagram ever produced, containing more than ten times more stars than any previous study.
