Giant stars also live fast and die young, burning through their fuel reserves in only a few million years. In comparison, the sun is less than halfway through its 10-billion-year lifespan. The combination of densely packed stars, relatively short lifetimes and vast astronomical distances makes distinguishing individual massive stars in clusters a daunting technical challenge.
