Sonifikasi: Mengubah Data Teleskopik kepada Muzik Kosmik

Sophie Kastner, a talented musical composer, embarked on an extraordinary project that defied conventional boundaries. She decided to translate intricate data from the heart of our Milky Way into a symphony, aptly named “Where Parallel Lines Converge.” The source of her inspiration was a composite image of the Galactic Center, captured by NASA’s Chandra, Hubble, and Spitzer telescopes, which showcased a mesmerizing collection of celestial phenomena.

Kastner’s goal was not to capture the entirety of this complex image but rather to focus on three specific elements: a double star system in X-ray wavelengths, a group of arched filaments, and the enigmatic supermassive black hole, Sagittarius A*. By highlighting these smaller events within the greater dataset, she aimed to draw listeners’ attention to the intricacies of the cosmic landscape.

But how does one convert astronomical data into music? In the vastness of space, sound waves cannot propagate, as there is no air or medium to carry them. However, NASA’s Chandra X-ray Center’s “sonification project” has successfully overcome this challenge by providing an alternative way to experience space exploration. This project takes X-ray telescope data and transforms it into audible sound, allowing for a deeper connection with the cosmos.

Through the sonification project, various astronomical phenomena have been interpreted sonically, including the supernova remnant Cassiopeia A, Stephan’s Quintet of galaxies, and images captured by the James Webb Space Telescope. This approach has been particularly applauded by the scientific community for enabling visually impaired space enthusiasts to engage with the wonders of the universe on a profound level.

It is important to note that the resulting musical compositions associated with these images are not recordings from space itself but rather artistic interpretations of the data. In essence, they serve as an audio representation of the scientific information, much like how the James Webb Space Telescope’s images are visual interpretations of infrared signals.

Sophie Kastner’s composition, “Where Parallel Lines Converge,” follows a unique structure, divided into three parts that traverse from left to right. Each part interprets specific elements of the Galactic Center image, with higher pitches representing objects located towards the top and the intensity of light dictating volume. Stars and compact sources are transformed into individual notes, while extended clouds of gas and dust produce an evolving drone.

By converging the realms of science and music, Kastner invites us to experience the wonders of the cosmos in an entirely different dimension. The sheet music for her composition is even available online, inviting aspiring musicians to take part in this cosmic journey.


Q: What is the sonification project?
A: The sonification project is an initiative by NASA’s Chandra X-ray Center that aims to transform X-ray telescope data into audible sound, allowing for a unique way to experience space exploration.

Q: Are the musical compositions associated with space images actual recordings from space?
A: No, the compositions are artistic interpretations of the data derived from astronomical images, providing an audio representation of the scientific information.

Q: How does sonification benefit visually impaired space enthusiasts?
A: Sonification allows visually impaired individuals to establish a deeper connection with the cosmos, enabling them to engage with the wonders of space exploration on a profound level.
