<ul><li>Peptides can form on cosmic dust despite water presence, challenging previous beliefs and suggesting a possible extraterrestrial origin for life's building blocks.</li><li>A research team has discovered that the presence of water molecules is not a major obstacle for the formation of peptides on cosmic dust particles.</li><li>The team replicated outer space conditions in a vacuum chamber and found that the formation of peptides can occur even with water-containing molecular ice.</li><li>While the presence of water slows down the peptide formation process, it is still feasible, indicating that outer space could be a potential source of life's biomolecules.</li></ul>
