Astronomical Sonification

Converting astronomical data into sound

Sonification represents real astronomical data through audio:

  • Alternative exploration method that can potentially reveal patterns less prominent in visual representations
  • Creates aurally pleasing and scientifically accurate representations of cosmic signals
  • Valuable tool for outreach and public engagement with astronomy
TXS 0506+056

🔊 Remember to play with sound! Sound-only MIDI available.

Sonification of real observations of the TXS 0506+056 blazar – the first known source of high-energy neutrinos:

  • Lightcurves spanning from gamma-rays (🛰️ Fermi) to multifrequency radio (📡 RATAN-600)
  • Each lightcurve is represented by a 🎹 piano note — higher frequencies mapped to higher pitches
  • Neutrino arrival (🧊 IceCube) marked by 🥁 cymbals
  • 👂 Listen for:
    • Gamma-ray peak aligns with neutrino arrival
    • Radio flares are delayed, with higher frequencies/pitches arriving before lower frequencies
