Biosignature Spotted on Venus

A team of astronauts said that phosphine is present on Venus, which could be originated geologically and not biologically. However, their researches have suggested that phosphine is often associated with microbes which could come from the volcanic eruptions on the surface of Venus.

Last year, a scientific debate announced that they had detected the presence of phosphine in’ atmosphere. However, further findings complicated the outcomes as the gas was not phosphine but Sulphur dioxide, according to another team. The recent findings were published in the journal Proceedings of the National Academy of Sciences.

Biosignature Spotted on VenusThe principle being indicated is that Venus’ deep covering could contain phosphorus compounds called phosphides. This could be burped into the atmosphere by volcanoes in the form of volcanic dust.Jonathan Lunine, a planetary scientist at Cornell University and co-author of the research paper, said that phosphine is not telling about the biology of Venus. It is instead describing the geology.

Science is indicating a planet that has active volcanic eruptions in the recent past. However, the mystery of Venus having phosphine or not is far from being settled. The tectonics of Venus are challenging to observe because of the planet’s dense atmosphere, which conceals its surface. Nevertheless, data released earlier showed that the planet might have active volcanic eruptions.

Three upcoming missions are set to talk more about Venus. Around 2030, NASA’s DAVINCI+ and VERITAS orbiter and the European Space Agency’s EnVision orbiter will all study its atmospheric makeup and surface tectonics, among other features of the nearest planets surrounding it.
