Spitzer Telecope Data Suggest that Life's Building Blocks are Abundant

Infrared astronomers are discovering that compounds called polycyclic aromatic hydrocarbons (PAHs) constitute one the largest reservoirs of carbon in space. New observations confirm that PAHs are abundant, even in distant galaxies. Investigator Doug Huggins notes that “This stuff contains the building blocks of life, and now we can say they’re abundant in space. And wherever there’s a planet out there, we know that these things are going to be raining down on it.”
