Scientists have discovered the EDGE of the Milky Way

"'Inside it, you have the part of the galaxy that is still actively building itself with ongoing star formation. Outside it, you have a disc region populated almost entirely by stars that have drifted there from elsewhere.'"

"As a galaxy forms, star formation begins earliest in the regions near the galactic centre, where gas and dust are densest before spreading out slowly over billions of years."

"The point where stars are at their very youngest marks the outer limit of the galaxy's star-forming region and the 'edge' of the galaxy."

Researchers have determined that the Milky Way's outer edge is about 40,000 light-years from the galactic center, with Earth located 13,300 light-years from this edge. The challenge in identifying the galaxy's edge arises from its gradual transition rather than a distinct boundary. The focus was on the limits of the star-forming region, where new stars are born. The youngest stars are found at the edge of this region, marking the galaxy's outer limits.
