🔊Sound on to hear the dulcet tones of the Milky Way.✨

The images of space you often see are visual representations of data captured by telescopes, with different colors for different elements or types of energy. Now scientists are turning that data from the @nasachandraxray—operated by the Smithsonian Astrophysical Observatory—and other telescopes into sound.

This sonification is of the center of our Milky Way galaxy, about 26,000 light years from Earth and 400 light years across. The translation moves left to right across the image, with sounds representing the position and brightness of the sources: xylophone for X-ray, violin for optical and piano for infrared light. Stars are individual notes, while extended clouds of gas and dust are a drone. Listen for the crescendo at the bright region on the lower right, the home of our galaxy’s supermassive black hole called Sagittarius A*.
