• # 53 - The exclusion of a significant range of ages in a massive star cluster
  • Hubble Space Telescope observations of the stellar cluster NGC 1651, which is approximately two billion years old, show that the colour–brightness distribution of stars old enough to have left the main sequence can be explained only by a single-age population, despite having a feature usually interpreted to indicate an age spread of more than 300 million years.
