Space vacuum does not allow sound to move between two objects in the same way as on Earth. Sound is the vibration emitted by one object that passes through a medium such as air until it is heard by another object. However, scientists were able to circumvent this limitation to invent novels to interpret signals emitted by space. Astronomers at the University of Wisconsin-Madison in the USA have isolated a special type of resonance caused by flashing stars.
These "vibrations" are fluctuations in temperature and brightness on the star's surface.
Powerful telescopes can capture these vibrations and recreate the sound of stars using computer simulations.
Jacqueline Goldstein, a graduate of astronomy in Wisconsin-Madison, said: "Cello sounds like a cello because of its size and shape.
"The vibration of the stars also depends on their size and structure."

However, at incredible frequencies in minutes to days, astronomers need to accelerate vibrations up to a million times to hear the human ear.
As a result, stellar vibrations are referred to as "starquakes," and the new field of study is called "astroseismology."
Astronomers hope the discovery can better understand the composition and structure of stars.
When a star joins hydrogen atoms with heavier elements such as helium, hot plasma or superheated gas causes the star to flicker.

Astronomers who closely observe these flickers can derive the structure of the star and how it will behave over time.
Mrs. Goldstein, who studies stars larger than our Sun, said, "These are the ones that explode and make black holes and neutron stars and all the heavy elements in the universe that make up planets and basically a new life."
“We want to understand how they work and how they affect the evolution of the universe. So these big questions. "
But this is not the first time astronomers have re-created the sounds of the universe.

In July 2018, NASA's Goddard Space Flight Center used data collected by the European Space Agency (ESA) to re-create the Sun's sound.
NASA and the ESA Solar and Heliospheric Observatory (SOHO) have collected data for 20 years during which the Sun's movements were recorded.
The data was then translated into a terrifying and incredibly low hum.
NASA's Alex Young said: "You hear the sun's vibrations. Almost has the heat for it.
“It's just enough where I feel the sound on my skin or on my clothes. I imagine the sun coming near me. "
