To sort out the development of the Milky Way through big data astronomy

Sorting out the evolution of our home galaxy, the Milky Way, is a challenge similar to mapping the human genome, according to the European Space Agency (ESA). ESA’s galaxy charter, Gaia, takes trillions of measurements of 2 billion of the brightest stars in the sky. Here we look at what it takes to remove these measurements to reveal the galaxy’s secrets.

June 13, the Gaia Data Processing and Analysis Consortium (DPAC), a collaboration between 450 European astronomers and supporting engineers galaxen-mapping endeavor, released what DPAC chairman Anthony Brown described as “the richest set of astronomical data ever published.”
