Wonders of the Chemistry of Life in Space: Proteins

[kit_hung]

New experiments have shown that protein building blocks can form naturally in deep space, under the extreme cold and intense radiation. Scientists have discovered that simple amino acids combine to form peptides on the surface of stardust, long before stars and planets came into existence.

The discovery challenges the idea that the complex chemistry of life occurs only on Earth. It also raises the possibility that the building blocks needed for life are widespread throughout the universe, opening the door to new hope for the origin of life beyond Earth.
