===================================

**Perseus Cluster:
Chandra "Hears" a Supermassive Black Hole in Perseus
For the first time, sound waves have been detected from a supermassive
black hole by using NASA's Chandra X-ray Observatory. The "note" is the
deepest ever detected from an object in the Universe. The tremendous
amounts of energy carried by these sound waves may solve a longstanding
problem in astrophysics.

===================================

++ Top Ten for Chandra's Fourth:
Among its array of revelations in the past 12 months, news about black
holes pulled in most of the headlines with four of the top five stories
from Chandra during its fourth year in operation. But it was the
venerable Crab Nebula, with the spectacular Chandra/Hubble movie
production of its amazing pulsar and dazzling tornado of high-energy
particles and magnetic fields, that captured first place as our most
popular image.
