Marcy, Geoffrey W. (1954–)
Professor of astronomy at the University
of California, Berkeley who, together with Paul Butler
and other colleagues, has been responsible for the discovery of well over
half the presently known extrasolar planets
and for obtaining evidence that (a) the solar system may be unusual in its
makeup, and (b) that brown dwarfs in
orbit around stars are surprisingly rare. Since 1998, Marcy has served on
the NASA working groups concerned with the Terrestrial
Planet Finder and the origin of the solar system. He obtained a B.A.
from the University of California, Los Angeles (1976), and a Ph.D. from
the University of California, Santa Cruz (1982).
