BRIEFING SEPT. 28 PRESENTS CHANDRA DISCOVERY 
OF RING AROUND COSMIC POWERHOUSE IN CRAB NEBULA

A new image from NASA's Chandra X-ray Observatory, to be presented 
at a Space Science Update at 1 p.m. EDT, Tuesday, Sept. 28, 
reveals a brilliant ring around a cosmic powerhouse at the heart 
of the Crab Nebula, the spectacular remains of a stellar 
explosion.  The briefing will be held in the James E. Webb 
Auditorium at NASA Headquarters, 300 E St. SW, Washington, DC.  
The ring is the first such structure ever discovered, and, along 
with observations from the Hubble Space Telescope, provides 
important clues to the puzzle of how the neutron star powerhouse 
energizes the Crab Nebula.
