Core Insights - A multinational team, including Associate Professor Zhang Zenghua from Nanjing University, has confirmed the detection of phosphine on an exoplanet, Wolf 1130C, which is expected to enhance the understanding of the chemical environment in the universe [1][2] - The research, published in the journal "Science," is considered a milestone, as phosphine has previously been detected in the atmospheres of Jupiter and Saturn, but not in other exoplanets [1][2] Group 1 - The detection of phosphine on Wolf 1130C, located 54 light-years away in a trinary star system, marks the first observation of this compound on an exoplanet [2] - The atmospheric modeling indicates that approximately 1 in every 10 million molecules in Wolf 1130C's atmosphere is phosphine [2] - The team is investigating two hypotheses for the presence of phosphine: one suggests a lack of sufficient oxygen on Wolf 1130C allows phosphorus to bond with hydrogen, while the other considers the possibility of phosphine originating from the neighboring stars [2][5] Group 2 - The international team, led by Professor Adam Burgasser from the University of California, San Diego, is planning new observations to search for phosphine on other brown dwarfs to further validate their theoretical assumptions [5]
