Pulsar music based on the data obtained from the Spectr-R space telescope and the Radioastron project. Pulsar is a rapidly rotating ultra high-density neutron star left over from a supernova explosion. Pulsar signals could be used as time references and navigation for satellites. By converting the frequency of pulsar signals into sound waves, you can compose music. Spectr-R is a space observatory launched in 2011. It was in orbit for 8 years, surpassing its warranty period by more than 2.5 times. The Radioastron project made a great contribution to the research of pulsars.
