Spirograph Nebula (IMAGE) University of Arizona Caption In this picture of the Spirograph Nebula, a dying star about 2,000 light-years from Earth, NASA's Hubble Space Telescope revealed some remarkable textures weaving through the star's envelope of dust and gas. UArizona researchers have now found evidence that complex carbon nanotubes could be forged in such environments.
