A recent scientific study has shown that the outer edge of the Milky Way galaxy is closer to Earth than previously expected.

The study conducted by researchers from the University of Insubria in Italy, in collaboration with an international research team, precisely determined the outer edge of the Milky Way galaxy’s disk, discovering that Earth is located 13,300 light-years from this edge. The study, led by Karl Vitini from the University of Insubria, relied on the analysis of data from over 100,000 giant stars to define the end of the “star formation region,” which is the area still witnessing the birth of new stars in the galaxy. The results showed that the edge of the galaxy’s disk is about 40,000 light-years away from the black hole at its center, while Earth is only 13,300 light-years from this edge, meaning it is closer to the outer boundaries of the galaxy than to its core. The researchers noted that determining this edge has posed a significant challenge for many years, as the galaxy does not end with sharp boundaries but rather gradually fades in density, making this discovery the first precise mapping of a clear geographical end of the place we inhabit within this vast universe.
