Barnard 68 appears to pulse once every 250,000 years
A massive molecular cloud in our galatic neighbourhood is pulsating in a way
that is puzzling U.S. astronomers, who said the phenomenon has never seen in
molecular clouds before.
Dr Charles Lada of the Harvard Smithsonian Centre for Astrophysics in Boston
and colleagues studied the dark molecular cloud known as Barnard 68 and found
the signatures of both in-falling and out-flowing material at different
locations across the face of the cloud.
The team described the observations as pulsing, or beating like a heart,
every 250,000 years. A paper describing the find was published yesterday in <A HREF="http://www.journals.uchicago.edu/ApJ/">
The Astrophysical Journal</A>.>>
