Hubble survey builds largest dataset on massive stars in early galaxies

A University of Utah-led Hubble Space Telescope survey has produced the largest dataset of its kind on massive stars in early galaxies. The data may explain the unusual properties of ancient galaxies through differences in their stars compared with the Milky Way.

• Survey led by the University of Utah using Hubble
• Focus on massive stars in early-universe galaxies
• Data may explain the puzzling traits of ancient galaxies
