By looking at the most distant Universe, astronomers are hoping to learn what kinds of galaxies formed first, leading through mergers to the mature galaxies we see today. The more galaxies you look at, the better the predictions. A team of French and Italian astronomers have used the VIsible Multi-Object Spectrograph (VIMOS) instrument on one of the ESO's 8.2 m telescopes to image and measure thousands of galaxies. They found 2 to 6 times as many early galaxies with vigorous star formation than astronomers had previously expected.
