Astronomers at Yale and Harvard have found a galaxy with a heartbeat - and they've taken its pulse. It is the first time scientists have measured the effect that pulsating, older red stars have on the light of their surrounding galaxy. The findings are published in the Nov. 16 online edition of the journal Nature.
