Nearby pulsating star cloud puzzles astronomers

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.
