Sound in Space: Astronomers ReveEal What Stars Sound Like and That Will AMAZE You Science | news



The vacuum of space does not allow the voice to move between objects in the same way it does on Earth. The sound is a vibration emitted by one object, which travels through a medium such as the air until it is heard by another object. However, scientists have succeeded in circumventing this limitation to create novels of interpretation of the signals emitted from the cosmos. Astronomers from the University of Wisconsin-Madison in the United States have isolated a strange type of resonance caused by flashing stars.

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

Powerful telescopes can lift these vibrations using computer simulations to reproduce the sound of the stars.

Klein Goldstein, a Wisconsin-Madison graduate astronomer, said: "It sounds like a lot to him because of its size and shape.

"The vibration of the stars depends both on their size and structure."

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

As a result, the staric vibrations are being referred to as "earthquakes" and the new field of study has been dubbed "astroseismology".

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

When a star unifies hydrogen atoms heavier elements such as helium, hot plasma or heated gas causes the jitter of a star.

Astronomers looking closely at these flashes can infer the structure of a star and how it behaves as time passes.

Ms. Goldstein, who studied stars bigger than our sun, said: "These are the exploding and making black holes and neutron stars and all the heavy elements in the universe that make up planets and actually a new life.

"We want to understand how they work and how they affect the evolution of the universe, so these are really big questions."

But this is not the first time astronomers have reproduced the sounds of the universe.

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 observations of NASA and ESA (SOHO) have collected data for 20 years, during which the sun's movements were recorded.

The data was then translated into a strange and frightening buzz.

NASA Alex Young said: "You actually hear the vibration of the sun. She almost has a fever.

"It's enough where I can feel the sound on my skin or on my clothes, I imagine how the sun flows next to me."
