READING: SUN’S
SOUND
What does the Sun sound like?
Perhaps you have never thought about what kinds of sounds the Sun
makes, but scientists have found out. Researchers from the European
Space Agency, NASA and the Solar and Heliospheric Agency studied 20
years of data to listen to the Sun. They say the Sun produces a
low, deep "heartbeat" sound. The scientists used a solar
observatory to measure vibrations from the Sun. They translated
these vibrations into different sounds. These can tell the
scientists what is happening inside the Sun. They can now
understand more about solar flares, chemical reactions and other
phenomena that happen inside the Sun and on its
surface.
The scientists explained how
they created the Sun's sound. Researchers from the Stanford
Experimental Physics Lab turned data from the space agencies into a
"song". Dr Alex Young said: "We don't have straightforward ways to
look inside the Sun. We don't have a microscope to zoom inside the
Sun, so using a star or the Sun's vibrations allows us to see
inside of it." Dr Young continued: "Waves are travelling and
bouncing around inside the Sun, and if your eyes were sensitive
enough, they could actually see this." He added: "We are finally
starting to understand the layers of the Sun and the complexity.
That simple sound is giving us a probe inside a star. I think
that's a pretty cool thing."
