Life's Building Blocks are Common in Space

[FLO]

NASA researchers have found that many of the basic building blocks for life here on Earth are common throughout the Universe. Using the Spitzer Space Telescope, the researchers observed that complex organic molecules called polycyclic aromatic hydrocarbons (PAHs) are everywhere they looked: in the Milky Way and in the most distant observable galaxies. Most of these molecules contain nitrogen, which is the key requirement for life.
