The double helix nebula as revelaed in the infrared by NASA’s Spitzer Space Telescope. The spots are infrared-luminous stars, mostly red giants and red supergiants. Many other stars are present in this region, but are too dim to appear even in this sensit

The double helix nebula is approximately 300 light-years from the enormous black hole at the center of the Milky Way. (The Earth is more than 25,000 light-years from the black hole at the galactic center.)

This false-color image was taken by the Multiband Imaging Photometer for Spitzer (MIPS).
