ASTRONOMER RUBIN TO LECTURE ON DARK MATTER ON NOV. 15

	CHARLOTTESVILLE, Va., Oct. 29 -- Internationally known
astronomer Vera C. Rubin will deliver the 29th annual Karl G. Jansky
Lecture at 8 p.m. on Tuesday, Nov. 15, in the Gilmer Hall auditorium
on the Grounds of the University of Virginia.  The lecture,
sponsored in part by the National Radio Astronomy Observatory
(NRAO), is aimed at non-scientists.
	Rubin, a scientist at the Carnegie Institution of Washington
and winner of the 1993 National Medal of Science, will speak on the
subject of Ôdark matter.Õ RubinÕs studies have focused on the
movements of galaxies.  According to her measurements, galaxies
display a rate of motion that indicates the presence of much more
material than is visible.  The amount and distribution of this
non-illuminated dark matter is a subject of much debate.  According
to NRAO scientist David Hogg, ÒIf Dr. RubinÕs measurements are
correct, and I believe they are, they reveal our lack of
understanding in some fundamental aspects of the universe.Ó
