The Helix Nebula is 655 light-years away and three light-years across. When a low-mass star sheds outer material near the end of its life, nebulae like this form. In this sonification, which scans from left to right, red light is assigned lower pitches and blue light is assigned higher pitches.
24 de abr. de 2020 · Hubble image of the Helix Nebula converted to sound. Colour is mapped to pitch (red=low, blue=high) and brightness controls volume. Red indicates the presence of hydrogen and nitrogen and...

The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from Earth's perspective, a helix structure.
Just as the frequencies of light increase from red to blue, frequencies of sound increase from low to high pitches. While there’s no sound in space, sonifications like this help us conceptualize the data in astronomical images in a new, auditory way!

4 de oct. de 2012 · The glow from planetary nebulae is particularly intriguing as it appears surprisingly similar across a broad swath of the spectrum, from ultraviolet to infrared. The Helix remains recognizable at any of these wavelengths, but the combination shown here highlights some subtle differences.
21 de mar. de 2006 · The Helix Nebula, a favorite target for amateur astronomers, is one of the closest planetary nebulae to Earth. Planetary nebulae are shells of gas expelled by dying stars. Explore the science along with the scenery – Image Tours show Hubble pictures through an astronomer's eyes, pinpointing and explaining key features to add ...
3 de sept. de 2020 · This Helix Nebula images contains infrared data from NASA’s Spitzer Space Telescope (green and red), optical light from Hubble (orange and blue), ultraviolet from NASA’s Galaxy Evolution Explorer (cyan), and Chandra’s X-rays (appearing as white) showing the white dwarf star that formed in the center of the nebula.
