Phosphine gas (a component of life) has been detected in the atmosphere of a brown dwarf (a failed star) called Wolf 1130C, which is approximately 54 light-years distant. The finding completely contradicts one of the most controversial concepts of astronomy: phosphine is a possible life indicator. The discovery, rather, indicates that this gas could be formed in extreme settings naturally, altering our perception of the potential indicators of life in the universe. Phosphine found on Wolf 1130C According to a paper, in October 2018, an international team observed Wolf 1130C with JWST and detected phosphine in its atmosphere with a concentration of approximately 0.1 parts per million. The presence of phosphine in cool, hydrogen-rich objects had been predicted by atmosphere models and thus was expected to be detected. Notably, the team emphasises the fact that Wolf 1130C is too cold and uninhabitable to support life of any kind, so the phosphine must have been produced non-biologically. ...
