The Perseus Molecular Complex is only visible when viewed through infrared instruments, and tryptophan gives off an identifiable light reading when observed in this way.
Amino acids have been found in the depths of spaceiStock
Dr Susana Iglesias-Groth is from the Instituto de Astrofísica de Canarias and was lead author on the new research.
"The evidence for tryptophan in the Perseus molecular complex should encourage additional effort to identify other amino acids in this region, and in other star-forming regions,” Dr Iglesias-Groth said.
“It is a very exciting possibility that the building blocks of proteins are widely present in the gas from which stars and planets form – it may be key for the development of life in exoplanetary systems.”
It comes after research showed that life forms could potentially be able to survive in the conditions in the clouds above Venus.
The key point revolves around the presence of the biosignature gas phosphine, which is often identified as a sign of life. It also posits the idea that potential life forms on the planet could use sulphuric acid the way life forms on Earth use water.
