Summary

New observations, combined with a new trick for estimating a galaxy's distance from its colors, show that starbirth peaked at about 12 times the current rate when the universe was about a third its current age. Because this peak is both higher and later than many astronomers had suspected, it's sending the theoreticians back to revise their models of galaxy formation.
