The rise and fall of galaxy formation

more »
Astronomers have charted the rise and fall of galaxies over 90 percent of cosmic history. The FourStar Galaxy Evolution Survey has built a multicolored photo album of galaxies as they grow from their faint beginnings into mature and majestic giants. They did so by measuring distances and brightnesses for more than 70,000 galaxies spanning more than 12 billion years of cosmic time, revealing the breadth of galactic diversity.
