Summary

SAN DIEGO-- In the second week of the new millennium, nearly 3000 scientists and educators gathered here for the 197th biannual meeting of the American Astronomical Society, held in conjunction with the American Association of Physics Teachers. Just a few miles from the city's world-famous zoo, speakers added bizarre new members to the cosmic bestiary, including the first evidence of the "event horizon" of a black hole, the first look at the accretion disk of a massive protostar, a pair of quasars that appear to contradict the big bang theory, and the largest coherent structure in the universe. (For an earlier report from the meeting, see Science, 19 January, p. 409.)
