Spitzer Finds Life Components in Young Universe
JPL — NASA’s Spitzer Space Telescope has found the ingredients for life all the way back to a time when the universe was a mere youngster.
Using Spitzer, scientists have detected organic molecules in galaxies when our universe was one-fourth of its current age of about 14 billion years. These large molecules, known as polycyclic aromatic hydrocarbons, are comprised of carbon and hydrogen. The molecules are considered to be among the building blocks of life.
