The European satellite Gaia has been continuously scanning the firmament for nearly ten years, charting it with unparalleled detail. Indeed, the spacecraft's observations and data have allowed us to make significant advances in our understanding of the galactic environment. However, the new data promises to expose even more remarkable information that go far beyond Gaia's original objectives. The Italian Space Agency and the National Institute of Astrophysics have been crucial in all of this. Today, just over a year after the publication of its most recent catalog, which contains the positions and characteristics of nearly two billion stars, the European Space Agency's satellite is prepared to open a new window on the Milky Way. Gaia, in fact, has determined the positions, movements on the plane of the sky, and parallaxes of over 500,000 stars all contained in a single star cluster, Omega Centauri, the largest globular cluster visible from Earth and an example of how a typical cluster of this type can look. These places, which are among the oldest in the Universe, are true cosmic fossils that can reveal important information about the origins of our galaxy. Gaia had not studied the area of sky occupied by Omega Centauri since it looks to be very densely populated with stars. Rather than focusing solely on individual stars, Gaia activated a special mode to truly map a larger area of sky surrounding the cluster's core each time the cluster appeared in view, allowing it to collect valuable information for each of the 500,000 stars in the cluster at the end of the process.
