| 説明 | This Hubble Space Telescope image of a sparkling jewel box full of stars captures the heart of our Milky Way galaxy.Aging red giant stars coexist with their more plentiful younger cousins, the smaller, white, Sun-like stars, in this crowded region of our galaxy’s ancient central hub, or bulge. Most of the bright blue stars in the image are probably recently formed stars located in the foreground, in the galaxy's disk. Astronomers studied 10,000 of these Sun-like stars in archival Hubble images over a nine-year period to unearth clues to our galaxy’s evolution.The study reveals that the Milky Way’s bulge is a dynamic environment of variously aged stars zipping around at different speeds, like travelers bustling about a busy airport.The center of our galaxy is about 26,000 light-years away.Credit: NASA, ESA, Tom M.
