What does a high 'metallicity' measurement in a star system suggest about the material it formed from?
Answer
It formed from material recently recycled through several supernova events
High metallicity implies a greater percentage of elements heavier than hydrogen and helium, indicating the gas cloud had already been enriched by the deaths of previous stellar generations.
