Stars Try to Hide Their Age Too

The open star cluster NGC 1755 is located in the Large Magellanic Cloud galaxy, next door to the Milky Way, and is 120 light-years across. The Hubble Space Telescope operated by NASA/ESA gazed into the heart of NGC 1755 to gain a better understanding of how different star populations can coexist in a single cluster.
