Antoine de Saint-Exupéry, The Little Prince
"I love listening to  the stars at night. It’s like listening to five hundred million little bells . . ."

AstroSounds approaches Astronomy from a different angle. Everyone thinks Astronomy aims mainly at visual observations (like pictures or stellar spectra), but it’s also possible to listen to the stars.
Stars vibrate like musical instruments. Like recognizing a musical instrument by the sound it makes, you can recognize a star by the sound it makes.



AstroSounds is a Citizen Science Project and wants to involve everyone, from all age groups, with this scientific research.

Tens of thousands 

Stars to classify. There are many more stars in our universe, but for now we focus on a small part of the sky.



Sinus curves processed. A star requires around 25 sinus curves to produce a realistic sound.

Why AstroSounds?

AstroSounds approaches Astronomy from a different angle. Everyone thinks Astronomy aims mainly at visual observations (like pictures or stellar spectra), but it’s also possible to listen to the stars.
Stars vibrate like musical instruments. We can recognize these instruments by their specific timbre. Similarly, we can recognize a star by the timbre of the star’s vibrations and sounds.
In other words, our ears are able to filter out data from stellar phenomena that might be less easy to distinguish by eye.
The new generation of space telescopes has generated an explosion of new astronomical data. Could the human ear be equipped to aid us in analyzing the huge influx of data? This hypothesis lies at the base of the AstroSounds Citizen Science Project. Therefore, a large group of people –students, their teachers and citizens in general – will listen to and analyze stellar data. AstroSounds wants everyone, regardless of age, to become an astro-listener.

A series of bookwidgets aids you to become an astro-listener step by step. This way, you help scientists to investigate in which way listening to the stars is helpful in broader Astronomical research.
AstroSounds is a part of the Astronomical research of Prof. Kolenberg (KU Leuven/UAntwerpen/VUB) and the blind researcher Dr. Diaz Merced, who received a PhD in 2013 on the analysis of stellar data based on audio. This scientific component is one of the key elements of AstroSounds.
