Researchers from the University of Birmingham detected ‘resonant acoustic oscillations’ inside stars in ‘M4’, one of the oldest known clusters of stars in the Galaxy, some 13 billion years old.
The ‘sounds’ lead to tiny changes or pulses in brightness – and could allow us to understand some of the most ancient stars in our galaxy.
Professor Bill Chaplin, from the University of Birmingham said: ‘Just as archaeologists can reveal the past by excavating the earth, so we can use sound inside the stars to perform Galactic archaeology.’
Dr Andrea Miglio of the University of Birmingham said: ‘We were thrilled to be able to listen to some of the stellar relics of the early universe. The stars we have studied really are living fossils from the time of the formation of our Galaxy, and we now hope be able to unlock the secrets of how spiral galaxies, like our own, formed and evolved.’
It sounds an awful lot like the kind of music Krugman posts on Friday night as his blog.
