Space - Terzan 5: uncovering a fossil fragment in our galaxy
Space · 0:45
In the crowded central bulge of the Milky Way, astronomers studying the stellar system Terzan 5 have reclassified it from a globular cluster to a bulge fossil fragment. Combining data from the Webb and Hubble space telescopes, researchers identified four distinct stellar populations spanning billions of years. Stars formed roughly 12.5, 4.7, 3.8, and 2.5 billion years ago. Packing two million times the mass of the Sun into just a few tens of light-years, Terzan 5 reveals how the galaxy's central bulge evolved over cosmic history.
