Black Hole Mayhem: New Results From Chandra And Xmm-Newton
 
 
New X-ray data from two orbiting satellites, providing the best evidence to date for a spectacular black hole event long predicted by theory but not confirmed until now, will be the subject of the next NASA Space Science Update (SSU).

The SSU starts at 1 p.m. EST on Wednesday, February 18, 2004, in the James E. Webb Auditorium, NASA Headquarters, 300 E St., S.W., Washington.

Science team leaders will present their findings for this discovery, which could provide crucial information about how these black holes grow and affect surrounding stars and gas. The SSU will be carried live on NASA TV with two-way question-and-answer capability for reporters covering the event at participating NASA centers.

Panelists:

    -- Dr. Stefanie Komossa, postdoctoral researcher, Max-Planck-Institute for Extraterrestrial Physics, Garching, Germany.
    -- Dr. Guenther Hasinger, astrophysicist, Max-Planck-Institute for Extraterrestrial Physics.
    -- Dr. Kim Weaver, astrophysicist, NASA Goddard Space Flight Center, Greenbelt, Md.
    -- Dr. Alex Filippenko, professor, University of California, Berkeley, Calif.
    -- Panel Moderator: Dr. Paul Hertz, Senior Scientist for Astronomy and Physics, Office of Space Science, NASA Headquarters, Washington.
