Strange sounds of the oldest stars

British scientists successfully reproduce the sound of some of the oldest stars in the Milky Way.

According to Cnet, the sound cannot travel through the vacuum of space, but some other forms of information in the universe such as radio waves and electromagnetic noise emitted from the star can be recorded and converted into sound. bar.

Scientists at the University of Birmingham, England, recreated the "music" of some of the oldest stars in the Milky Way, located in the Messier 4 globular cluster of about 12.2 billion years old.

The team used asteroseismology technique , which translates as seismic , to understand the resonant resonance of stars . Minor changes in star brightness caused by thermal energy are converted into kinetic energy in light pulses. This allows scientists to study the internal structure and age of stars, like the seismic field that explores the inner structure of the Earth.
