The vacuum of space does not allow sound to travel between two objects in the same way as it does on Earth. Sound is a vibration that is emitted by an object that moves through a medium such as air until it is heard by another object. However, scientists were able to circumvent this limitation in order to develop novels in the interpretation of the signals emitted by the cosmos. Astronomers at the University of Wisconsin-Madison in the US have isolated a special kind of resonance caused by flashing stars.
These "vibrations" are temperature and brightness fluctuations on the surface of a star.
Powerful Telescopes Can Record These Vibrations And Create The Sound Of The Stars Through Computer Simulations.
Jacqueline Goldstein, an astronomy student in Wisconsin-Madison, said, "A cello sounds like a cello because of its size and shape.
"The vibrations of the stars also depend on their size and structure. "

But at incredible frequencies in the range of minutes to days, astronomers need to accelerate the vibrations of human hearing by as much as one million To hear.
As a result, the stellar vibrations are called "starquakes" and the new study area is called "astroseismology". [1
When a star combines hydrogen atoms with heavier elements such as helium, hot plasma or superheated gas causes the star to flicker.

Astronomers attentive to this flicker can derive the structure of a star and its behavior over time.
Ms. Goldstein Studying Stars Bigger Than Our Sun said, "These are the ones that explode, forming black holes and neutron stars, as well as all the heavy elements in the universe that make up planets and essentially new life.
"We want to understand how they work and how they affect the evolution of the universe. So these really big questions. "
But this is not the first time that astronomers have recreated the sounds of the cosmos.

In July 2018, NASA's Goddard Space Flight Center used data collected by the European Space Agency (ESA) to recreate the sound of the sun.
The Solar and Heliospheric Observatory (SOHO) of NASA and ESA) collected data over a 20-year period in which solar motion was recorded.
The data was then translated into an eerie and unbelievably quiet buzz.
Alex Young of NASA said, "You actually hear the vibration of the sun. It has almost a warmth.
"It's just enough where I can feel the sound on my skin or on my clothes. I can imagine the sun running next to me. "
