MEXICO: Astronomers recently provided the details of unprecedented life story of Milky Way galaxy evolution through a movie by studying how galaxies like our own formed.
The most comprehensive multi-observatory galaxy surveys to date led by Texas AandM University’s Casey Papovich , astronomers have come up with the next best thing, the evolution of the Milky Way in pictures, pieced together using data from NASA and European Space Agency space telescopes and ground-based telescopes as well as thousands of snapshots of galaxies similar in mass to the Milky Way.
Papovich, along with Texas AandM postdoctoral researchers Vithal Tilvi and Ryan Quadri and roughly two dozen astronomers around the world, spent a year studying carefully selected distant galaxies similar in mass to the progenitor of our own Milky Way that were found in two deep-sky program surveys of the universe, the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and the FourStar Galaxy Evolution Survey (ZFOURGE).
