The Four Light Curves of the K2-187 Exoplanets Converted Into Music @SYSTEMSounds

The four planets of K2-187 were discovered by looking for slight dips in the brightness as each one passes in front of their star (the 'transit' method). We have converted the brightness data into musical notes by assigning the dimmer measurements to lower notes. The data is mapped to the harmonic minor scale to match the actual harmony that these planets produce when their motion is converted into musical pitches (see link below). Melodic and rhythmic patterns emerge as a result of overlaying the data from several transits of each planet.

$Sonification of Every Gravitational Wave Experience the cosmic symphony of gravitational waves! This is a sonification of the first 90 confirmed gravitational wave detections, each the result of merging black holes and/or neutron stars. The extracted waveforms are synthesized and played as audio in the actual sequence they were discovered. In the final seconds of each merger the black holes and neutron stars orbit each other faster and faster, reaching frequencies of 10s or 100s of times per second. These frequencies are within the human hearing range so we can listen to each merger unfold in real time. The increasing frequency of their spiralling dance creates a characteristic chirp sound, marking the moment they finally merge. The time between each merger is compressed to let you experience the rhythm and variety of these remarkable cosmic collisions. The first gravitational wave was detected in 2015 using 4km long laser interferometers called LIGO. The black hole merger that created this wave happened over a billion light years away, and hence over a billion year ago. Over the course of 3 observing runs, 89 more gravitational waves were detected, and at an increasing rate as the sensitivity of the detectors was improved. The 4th observing run started on May 24 2023 and holds the promise of even more astounding discoveries. The black holes and neutron stars involved in these mergers are each 10s of kilometers across and orbit each other at a sizeable fraction of the speed of light. In the final few milliseconds the merger releases energy at a greater rate than all of the stars in the observable universe combined. This energy radiates as gravitational waves, carrying the signature of this cataclysmic event across the universe.
