NASA TO ANNOUNCE EXTRAORDINARY STELLAR DISCOVERY

WASHINGTON - At a NASA Science Update Monday, May 7, at 2 p.m. EDT,
astronomers will announce new findings about a record-breaking
stellar event discovered using NASA's Chandra X-ray Observatory. The
event will be held in the auditorium at NASA Headquarters, 300 E St.,
S.W., in Washington and will be broadcast live on NASA Television and
streamed at http://www.nasa.gov.

Media at participating NASA centers will have the opportunity to ask
questions.

The Chandra X-ray Observatory is the world's most powerful X-ray
telescope. Chandra is designed to observe X-rays from high-energy
regions of the universe, such as the remnants of exploded stars.
Along with the Hubble Space Telescope, the Spitzer Space Telescope,
and the now de-orbited Compton Gamma Ray Observatory, Chandra is one
of NASA's "Great Observatories."

The Smithsonian Astrophysical Observatory in Cambridge, Mass., is
responsible for the day-to-day ?ight operations and science
activities for Chandra from the Operations Control Center and Chandra
X-ray Center facilities.
