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.
