The light emitted from the most distant galaxies travels for billions of years before reaching us. Astronomers use this to their advantage in order to sample galaxy properties at different cosmic epochs. This rendering of the Hubble UDF shows how the ASPECS team used ALMA to trace the dust and gas emission in galaxies at various distances to reconstruct the evolution of the gas and dust content of galaxies through cosmic time.
