A staff of researchers has claimed to have found glycine – an amino acid molecule that kinds proteins in dwelling organisms – within the environment of Venus. Lead writer of the research Arijit Manna, a PhD Analysis Scholar from the division of Physics at Midnapore School in West Bengal, India, alongside together with his staff of researchers used the Atacama Massive Millimeter/ submillimeter Array (ALMA) to detect glycine within the environment of Venus utilizing spectroscopy. The researchers detected glycine concentrations within the mid-latitudes, close to the equator, the place the sign was strongest. No glycine was discovered close to the poles.

Writing concerning the research, researchers wrote that the detection of glycine within the environment of Venus could also be one of many keys in direction of understanding the formation of mechanisms of prebiotic molecules in Venus’ environment.

“The higher environment of Venus could also be going by almost the identical organic methodology as Earth billions of years in the past,” researchers added.

Whereas there are about 500 recognized amino acids, solely 20 p.c are current within the genetic code of which glycine is the only kind. The outcomes of the research is on the pre-print web site Arxiv.org.

This isn’t the primary time that researchers discovered a biosignature on Venus. Researchers reported discovering phosphine within the higher environment of Venus in mid-September.

Scientists at MIT, Cardiff College, and elsewhere, led by Jane Greaves of Cardiff College, detected in Venus’ atmosphere a spectral fingerprint, or light-based signature, of phosphine. The researchers made the invention utilizing Hawaii’s James Clerk Maxwell Telescope (JCMT), and the Atacama Massive Millimeter Array (ALMA) observatory in Chile.
