Tormod Posted October 31, 2005 Report Share Posted October 31, 2005 The idea that comets and meteorites seeded an early Earth with the tools to make life has gained momentum from recent observations of some of these building blocks floating throughout the cosmos. Scientists scanning a galaxy 12 million light-years away with NASA's Spitzer Space Telescope detected copious amounts of nitrogen containing polycyclic aromatic hydrocarbons (PANHs), molecules critical to all known forms of life. "This stuff contains the building blocks of life, and now we can say they're abundant in space," Hudgins said. "And wherever there's a planet out there, we know that these things are going to be raining down on it. It did here and it does elsewhere."
