Most Detailed Map of the Milky Way Unveiled

After 13 years of observations, astronomers from the European Southern Observatory (ESO) have unveiled the most detailed map of the Milky Way ever made, covering 1.5 billion stars, moons, and planets. The VISTA Variables in the Vía Láctea extended (VVVX) survey, compiled from over 200,000 images, used infrared light to peer through the gas and dust that typically obscure the galaxy's core. This vast map, capturing the movement and birth of stars as well as extremely cold objects, provides unprecedented detail on the Milky Way's structure, evolution, and hidden mysteries. The data, comprising 500 terabytes, will serve as a foundation for future astronomical research, offering insights into phenomena like ancient star clusters and free-floating planets. Researchers are now upgrading the telescope for even deeper exploration.
