NASA researchers have discovered that a mission to Venus in 1978 may have detected the presence of phosphine behind
The probe collected samples and sent them back toresearchers analyzed them. However, the scientists did not emphasize that the data also contained information about phosphine and other phosphorus-based compounds. The data was still available for re-examination, which the scientists did.
These data also show the presence of phosphorus compounds. Then it turned out that the substance is found mainly in the equator, at an altitude of 53–61 km above the planet's surface.

Venus could be habitable today if not for Jupiter
“The news inspired us to re-analyzedata to search for evidence of phosphorus compounds, the researchers noted. Published mass spectral data correspond to gases at altitudes of 50-60 km or within the lower and middle clouds of Venus - which has been identified as a potential habitat. We find the LMNS data support the presence of phosphine, although the origin of the phosphine remains unknown. ”
NASA admits scientists have discovered phosphine yetfour decades ago, but did not understand it. "This is pretty wild, and makes you wonder what other discoveries were made unknowingly over the decades when NASA and other space agencies conducted missions into space," the BGR reporters note.
