Scientists have pinpointed where our galaxy's star-forming region actually ends—about 35,000 to 40,000 light-years from the center—using a clever technique called stellar age mapping. This discovery reveals a clear U-shaped pattern that explains how stars behave at the galaxy's edges, finally answering a question astronomers have puzzled over for years.
