NASA SCHEDULES HUBBLE SCIENCE UPDATE FOR MAY 31 (UPDATE TIME CHANGE)



WASHINGTON -- NASA will host a Science Update Thursday, May 31, at
1:00 p.m. EDT to discuss new Hubble Space Telescope observations that
allow astronomers to predict with certainty the next major cosmic
event to affect our entire galaxy, sun, and solar system.

The news conference will be held in NASA Headquarters' James E. Webb
Auditorium at 300 E St. SW in Washington and be shown live on NASA
Television and on the agency's website.

It has been known for a long time that the Andromeda galaxy is
approaching us. Because of uncertainties in Andromeda's motion, it
has not been possible to determine whether the Milky Way will have a
head-on collision or glancing blow with the neighboring galaxy
billions of years in the future. Hubble's precise observations will
settle this question.

The briefing participants are:
-- Roeland van der Marel, astronomer, Space Telescope Science
Institute, Baltimore
-- Sangmo Tony Sohn, astronomer, Space Telescope Science Institute,
Baltimore
-- Rosemary Wyse, professor, Physics and Astronomy, Johns Hopkins
University, Baltimore
-- John Grunsfeld, Associate Administrator, Science Mission
Directorate, NASA Headquarters, Washington

Media can attend the event or ask questions by phone. For dial-in
information, reporters must send an email listing their name, phone
number and media affiliation to j.d.harrington@nasa.gov by noon on
May 31.

Following the news conference, the panelists also will host a web chat
at 3 p.m. to answer questions from the general public. Participate by
