5,000 Exoplanets: 30 years of sonified exoplanet discoveries

Watch more with these video collections:

From 1992 to 2022. From zero to 5,000. By turning NASA data into sound, this Sounds of Discovery animated video celebrates the March 21, 2022 discovery of the 5,000th confirmed exoplanet, beginning with the discovery of two exoplanets in 1992.

“As each exoplanet is discovered, a circle appears at its position in the sky. The size of the circle indicates the relative size of the planet’s orbit and the color indicates which planet detection method was used to discover it. The music is created by playing a note for each newly discovered world. The pitch of the note indicates the relative orbital period of the planet. Planets that take a longer time to orbit their stars are heard as lower notes, while planets that orbit more quickly are heard as higher notes.”

NASA also created this 360Β° data sonification animation:

“Exoplanet detection methods: radial velocity (pink); transit (purple); imaging (orange); microlensing (green); timing variations (red); orbital brightness modulation (yellow); astrometry (gray); disk kinematics (blue).”
