New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. Scientists found that simple amino acids bond into peptides on interstellar dust, long before stars and planets exist. This challenges the idea that complex life chemistry only happens on planets. It also boosts the odds that life-friendly ingredients are widespread across the universe.
