Ordinarily, Ellis explains, you could never see small galaxies a mere 500 million years after the Big Bang; they're just too faint for any telescope now in existence. But the universe itself has supplied a way of boosting a telescope's magnifying power. The theory of relativity says massive...
Einstein was wrong. So-called gravitational lenses have become a major factor in modern astronomy. They have revealed, among other things, the existence of tiny planets around stars thousands of light-years away and have created weird optical effects, including multiple images of faraway quasars. If you look at a...
For an hour or so, it looked as though they wouldn't get the chance. They had just this one night at the Keck; the telescope is so overbooked that even an eminent astronomer like Ellis has to wait his turn, and his next observing run isn't until January...
"It's regrettable that we couldn't check the other three," Ellis says a few days later, "but we're now very confident and very excited. If we've found this many in such a tiny area of the sky, there could be enough of these small galaxies to supply...
