Scientists have learned to read the history of galaxies from their photographs, like detectives from clues. It turns out that shape and color tell about age and dust more accurately than expensive spectra. The new method combines both approaches and promises a revolution in cosmic surveys.
🎯 Dust in galaxies doesn't just hinder observations — it tells its own story of star birth and death, because it consists of heavy elements ejected by old stars.
