LENGKONG, AYOBANDUNG.COM – There is no way to hear you scream while in space. However, on Earth, there are ways to change objects outer space be a sound.
Galaxy, black hole (black holes), and the nebula comes alive through audio, which provides new ways for humans to interact with the cosmos. A team of scientists translated data collected by the American Space Agency’s (NASA) Chandra X-ray Observatory and the telescope outer space others become sound using a process called data sonification.
Reported by Cnet, in this project, musician Andrew Santaguida from System Sounds, a science and arts outreach project was involved. On Wednesday (24/3), NASA released a new audio track that allows listening to observations of Chandra Deep Field, the Cat’s Eye Nebula, and Galaxy Whirlpool. The three of them have different sonic characteristics, ranging from light and subtle to almost creepy.
“This is the deepest image ever taken in X-rays representing more than seven million seconds of Chandra’s observation time,” NASA said.
Chandra Deep Field South, an in-depth view of the southern hemisphere of the sky is at the brighter end of the sound spectrum. Sonification of Deep Field South’s data has the feel of a poppy ’80s science fiction soundtrack.
The dots on the image are mostly representative black hole and galaxy. The wide range of musical frequencies represents all X-ray frequencies that Chandra collects in this region.
Scientists also sonified the Cat’s Eye Nebula. To listen to this data, there is a clockwise radar-like scan that radiates from the center point to produce a tone.
“Light farther from the center sounds a higher tone while brighter light sounds louder,” NASA explained.
The Cat’s Eye Nebula, also known as The Cat’s Eye, appears on the Vangelis soundtrack from Blade Runner.
The third data sonification is Messier 51, which is more popularly known as Galaxy Vortex for the swirling view of Earth’s spiral arms. The radius maps to the notes of the melodic minor scale.
NASA mentions that each wavelength of light in the image is obtained from the telescope on outer space, including infrared, optical, ultraviolet, and X-rays assigned to different frequency ranges.
There is a lot more tension in the sound landscape for Messier 51. This sound could seem appropriate for a scene in a horror film, where a character roams a haunted house.
Data sonification techniques have been used to translate Martian sunrises and suns into sound. The latest Chandra audio release is part of an ongoing project creating telescope data outer space available in new ways.
The experience of the cosmos does not have to be limited to the visuals. The universe can be beautiful and terrifying at the same time, when you take the time to listen to it.
