The objects Marcy looks at aren't especially faint: he and his collaborators find planets by looking for stars that wobble under the gravitational tug of unseen companions. But the wobbles are so subtle that a lesser telescope can barely detect them. "With a 10-m telescope," says Marcy, "we...
Indeed, Marcy announced last year that he'd found a planet the size of Saturn--the smallest yet discovered. "We think we can get down to the level of Neptunes," he says, "which are only 10 times as massive as Earth." Despite having so many planets in hand, Marcy and...
George Djorgovski is using the Keck as well, but where Marcy's quarries are no more than 200 light-years way, Djorgovski's are closer to 10 billion. A professor at Caltech, Djorgovski has lately been concentrating on gamma-ray bursts--mysterious flashes of high-energy radiation that have baffled...
UCLA astronomer Andrea Ghez, meanwhile, has focused her attention on the center of our home galaxy, the Milky Way, far closer than Djorgovski's gamma-ray bursts but hundreds of times farther away than Marcy's planets. Shrouded in thick clouds of dust, the galactic core is invisible to ordinary...
