LISTEN UP: CHANDRA DETECTS POWERFUL BLACK HOLE SOUND WAVES

NASA's Chandra X-ray Observatory detected sound waves coming from a super massive black hole. The first of its kind discovery found these sound waves carry enormous
amounts of energy.

At NASA's next Space Science Update (SSU), an international team of scientists will discuss this unique discovery of black hole sound waves and its implications. The SSU isTuesday, September 9, at 1:00 p.m. EDT from NASA's James E. Webb Auditorium, 300 E St., S.W., Washington.

SSU panelists:

-- Dr. Andy Fabian, professor, Institute of Astronomy, Cambridge, U.K.
-- Dr. Steve Allen, astrophysicist, Institute of Astronomy, Cambridge, U.K.
-- Dr. Kim Weaver, astrophysicist, NASA Goddard Space Flight Center, Greenbelt, Md.
-- Dr. Bruce Margon, associate director for science, Space Telescope Science Institute, Baltimore.
-- Panel Moderator: Dr. Anne Kinney, director of the Astronomy and Physics Division, Office of Space Science, NASA Headquarters.

The SSU will be carried live on NASA Television with two-way question-and-answer capability for reporters covering the event from participating agency centers. NASA TV is broadcast on AMC-9, transponder 9C, C-Band, located at 85 degrees west longitude. The frequency is 3880.0 MHz.
Polarization is vertical, and audio is monaural at 6.80 MHz. Audio of the SSU is available on voice circuit from the Kennedy Space Center at: 321/867-1220.
