NASA’s project presents astronomical data in a format we’re not accustomed to: music

Let’s get this clarification out of the way: space telescopes don’t record sounds. Sound is a mechanical wave that needs a medium, such as air, to propagate The space is empty. However, during the pandemic, NASA began working with musicians and digital artists to “record” observations from one of its space telescopes.

In addition to having an unoriginal name, Galactic center It is hidden from the naked eye by stardust, but the Chandra telescope is able to capture in a variety of wavelengths (X-ray, infrared and visible light) the gas swirls and lines woven by magnetic fields in this place on the Milky Way planet, where there is a supermassive black hole. .
