That’s the debut record from an artist that’s been making music for billions of years.


According to Time, scientists at Sheffield University in the UK have discovered that the sun makes music. The recording posted above is a reproduction of what one would hear if it was possible to stand inside what’s called the solar corona, the upper layer of the sun’s atmosphere.

The solar corona is filled with 60,000-mile-long plasma structures known as coronal loops. These loops sometimes vibrate side-to-side and other times stretch and contract along their lengths, producing what a physicist would call transversal oscillations and longitudinal oscillations — in other words, music (Plucking a stringed instrument produces transversal oscillations; longitudinal oscillations occur when you blow into a wind instrument).

The reproductions of solar songs are pretty accurate representations. Scientists at Sheffield compiled a catalog of high-resolution videos and still images of the sun shot by satellite observatories, then used a computer algorithm that converted the visual data to acoustical information and sped up the frequency so the sound would fall within the human auditory range. This process is essentially an audio version of what is done in order to convert raw digital images from interplanetary probes into vivid color.

The solar music will allow scientists to better understand the sun’s atmosphere, and in turn predict solar storms. These storms can cause disruptions to power grids and electronic communications on earth. Careful analysis of the sun’s music could actually help us continue to enjoy recorded music on earth.

There’s something sort of intimidating about reviewing the sun’s music, so we’re not gonna get into detail, but if you ask us, it totally sounds like an Aphex Twin rip-off.

That is quite cool. KSUN broadcasting from the center of the solar system.

Music in the brain
For the first time, scientists identify a neural population highly selective for music.

Scientists have long wondered if the human brain contains neural mechanisms specific to music perception. Now, for the first time, MIT neuroscientists have identified a neural population in the human auditory cortex that responds selectively to sounds that people typically categorize as music, but not to speech or other environmental sounds.

“It has been the subject of widespread speculation,” says Josh McDermott, the Frederick A. and Carole J. Middleton Assistant Professor of Neuroscience in the Department of Brain and Cognitive Sciences at MIT. “One of the core debates surrounding music is to what extent it has dedicated mechanisms in the brain and to what extent it piggybacks off of mechanisms that primarily serve other functions.”

The finding was enabled by a new method designed to identify neural populations from functional magnetic resonance imaging (fMRI) data. Using this method, the researchers identified six neural populations with different functions, including the music-selective population and another set of neurons that responds selectively to speech.

“The music result is notable because people had not been able to clearly see highly selective responses to music before,” says Sam Norman-Haignere, a postdoc at MIT’s McGovern Institute for Brain Research.

“Our findings are hard to reconcile with the idea that music piggybacks entirely on neural machinery that is optimized for other functions, because the neural responses we see are highly specific to music,” says Nancy Kanwisher, the Walter A. Rosenblith Professor of Cognitive Neuroscience at MIT and a member of MIT’s McGovern Institute for Brain Research.

Norman-Haignere is the lead author of a paper describing the findings in the Dec. 16 online edition of Neuron. McDermott and Kanwisher are the paper’s senior authors.
