Time for Thorns

An independent view on life.

Galactic archaeology…

Professor Bill Chaplin,  from the University of Birmingham,  says we can use the sounds coming from inside of stars to learn about them,  much the same way archaeologists excavate the earth to uncover the past.   This makes sense if you consider that they just recorded  ‘resonant acoustic oscillations’  inside stars in ‘M4’,  one of the oldest known clusters of stars in the Galaxy,  some 13 billion years old.

These  ‘sounds’  lead to tiny changes or pulses in brightness,  and though they have been compared to the odd groans malfunctioning computers make,  I prefer to think of them as the  stars singing.
