  • A team of international scientists have detected traces of phosphine gas in the atmosphere of Venus.
  • On Earth, phosphine is produced by bacteria thriving in oxygen-starved environments.
  • So, the detection indicates the possibility of the presence of lifeforms on Venus.
  • Phosphine also arises non-biologically in certain industrial settings.
  • It was used as a chemical weapon during World War I.
  • Phosphine is still manufactured as an agricultural fumigant.
  • It is used in the semiconductor industry, and is a by-product of meth labs.
