We performed a refined\nanalysis of infrared observations of the nucleus of comet 67P carried out by\nthe VIRTIS-M hyperspectral imager. We found that the overall shape of the 67P\ninfrared spectrum is similar to that of other carbon-rich outer solar system\nobjects suggesting a possible genetic link with them. More importantly, we are\nalso able to confirm the complex spectral structure of the wide 2.8-3.6 micron\nabsorption feature populated by fainter bands. Among these, we unambiguously\nidentified the presence of aliphatic organics by their ubiquitous 3.38, 3.42\nand 3.47 micron bands. This novel infrared detection of aliphatic species on a\ncometary surface has strong implications for the evolutionary history of the\nprimordial solar system and give evidence that comets provide an evolutionary\nlink between interstellar material and solar system bodies.', 'mimetype': 'text/plain', 'lang': 'en'}
