NASA Announces Virtual News Briefing
 
 
NASA is sponsoring a Web-based and telephone news media conference on Thursday, September 23, at 1 p.m. EDT.

Scientists will describe a cosmic hurricane, as two merging galaxy clusters churn high-pressure shock waves leaving thousands of galaxies strewn in the wake. The European Space Agency XMM-Newton observatory observed the event, which captures the essence of how the universe built its hierarchal structure.

Briefing participants:

-- Dr. Michael Salamon, Discipline Scientist, Universe Division, Science Mission Directorate, NASA Headquarters, Washington
-- Dr. J. Patrick Henry, Professor of Astronomy, Institute for Astronomy, University of Hawaii, Honolulu
-- Dr. August Evrard, Professor of Physics and Astronomy, University of Michigan, Ann Arbor, Mich.
-- Dr. Richard Mushotzky, U.S. Project Scientist for XMM-Newton, NASA Goddard Space Flight Center, Greenbelt, Md.

This Web-based news conference is only for news media reporters. Accompanying graphics and images will be available on the Web. Participants will answer news media questions at the end of the briefing.
