Black Hole Mayhem: New Results From Chandra And XMM-Newton
The Space Science Update (SSU) originally scheduled for 1 p.m. EST Wed. Feb. 18, will be delayed one hour and will begin at 2 p.m. EST Wed. Feb. 18, in the James E. Webb Auditorium, NASA Headquarters, 300 E St., S.W., Washington.
The SSU will be web cast live on: http://www.nasa.gov
Reporters not participating at NASA Centers can phone in with questions at: 202/358-7020 and 202/358-7021.
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 SSU.
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.
