Just over twenty years ago, it was realized that our Milky
Way Galaxy and thousands of galaxies nearby are moving
through the universe at a speed of about two million
kilometers per hour. The best explanation is a massive
structure, some 200 million light-years away, that was named
the "Great Attractor". Studies of large scale structure have
revealed both that the Great Attractor is a massive 'wall'
of galaxies and that an even more massive collection of
galaxies exists still farther away, called the Shapley
Supercluster. Dr. Radburn-Smith will explore the history of
and new discoveries about these structures in a quest to
uncover the gravitational influences responsible for our
motion through the universe.


Lectures on a diverse selection of cosmic topics are held
the first Tuesday of every month at 8 PM in the STScI
Auditorium, located at 3700 San Martin Drive on the Homewood
campus of Johns Hopkins University. Admission is free and free
parking is available in the lot across the street.

This lecture will be webcast live. The recorded webcast will
also be available for viewing online the following day. To
