Riess's colleagues are most impressed with his willingness to challenge his own work. "Instead of making an emotional commitment to the accelerating universe," says Harvard's Robert Kirshner, one of the team's leaders, "Adam is always trying to see whether we've done things right."
Evidently they have. A second group came up with the same result at about the same time, and the journal Science named the accelerating universe Discovery of the Year for 1998. Riess, 30, now at the Space Telescope Science Institute in Baltimore, Md., is trying to push the observations beyond the edge. "In the past year," he says, "we've been finding supernovas further away than ever." Who knows what mysteries these distant beacons might reveal?
