Sound in space: Astronomers REVEAL what the stars sound and will AMAZE you | Contact Us | News

The void of space does not allow sound to travel between two objects in the same manner as on Earth. Sound is a vibration emitted by an object, which travels through a medium, such as air, until it is heard by another object. Scientists, however, were able to circumvent this limitation to invent novels of interpretation of the signals emitted by the cosmos. Astronomers at the University of Wisconsin-Madison in the United States have isolated a peculiar kind of resonance caused by blinking stars.

These "vibrations" are fluctuations in temperature and brightness on the surface of a star.

Powerful telescopes can capture these vibrations and, through computer simulations, recreate the sound produced by the stars.

Jacqueline Goldstein, a Wisconsin-Madison graduate astronomy student, said, "A cello sounds like a cello because of its size and shape.

"The vibrations of stars also depend on their size and structure."

But at incredible frequencies in the range of minutes to days, astronomers need to accelerate vibrations by up to a million times for the human ear to hear.

As a result, stellar vibrations are being called "starquakes" and the new field of study has been dubbed "astrossismology."

Astronomers hope the discovery will help them better understand the composition and structure of stars.

When a star fuses hydrogen atoms into heavier elements, such as helium, hot plasma or overheated gas, it causes the star to glisten.

Astronomers who watch these oscillations closely can deduce the structure of a star and how it will behave with the passage of time.

Ms 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 form planets and essentially a 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 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 Sun's sound.

The NASA and ESA Solar and Heliospheric Observatory (SOHO) collected data over a 20-year period, during which the sun's movements were recorded.

The data was then translated into a sinister and incredibly low buzz.

Alex Young of NASA said, "You're really listening to the vibration of the sun. It's almost too hot for that.

"It's just enough where I can feel the sound on my skin or my clothes. I can imagine feeling the sun moving beside me.
