Data from ESA (European Space Agency) and NASA's Solar and Heliospheric Observatory (SOHO) has captured the dynamic movement of the Sun's atmosphere for over 20 years. Today, we can hear the Sun's movement -- all of its waves, loops and eruptions -- with our own ears.
This sound helps scientists study what can't be observed with the naked eye.
"Waves are traveling and bouncing around inside the Sun, and if your eyes were sensitive enough they could actually see this," said Alex Young, associate director for science in the Heliophysics Science Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Data from SOHO, sonified by the Stanford Experimental Physics Lab, captures the Sun's natural vibrations and provides scientists with a concrete representation of its dynamic movements.
"We don't have straightforward ways to look inside the Sun. We don't have a microscope to zoom inside the Sun," Young said. "So using a star or the Sun's vibrations allows us to see inside of it."
These vibrations allow scientists to study a range of complex motions inside the Sun, from solar flares to coronal mass ejections.
"We can see huge rivers of solar material flowing around. We are finally starting to understand the layers of the Sun and the complexity," Young said. "That simple sound is giving us a probe inside of a star. I think that's a pretty cool thing."
The sounds of the Sun are on display at the NASA Goddard Visitor Center in Greenbelt, Maryland. An immersive art installation, called Solarium, uses vivid imagery and sonification to transport listeners to the heart of our solar system.

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
