Africa-Press – Rwanda. <\/strong><\/span>The mechanism explored by the authors of the new research may explain why some of Jupiter\u2019s moons have oxygen but do not host life.<\/p>\n

The presence of oxygen on exoplanets may not necessarily be a sign of life thriving on those distant worlds, a study published in Science Advances has suggested.<\/p>\n

Produced in vast quantities by plants and bacteria on our planet, oxygen is vital to life on Earth. The new research, however, points out that this gas is not necessarily produced through photosynthesis, but can also come from an abiotic source.<\/p>\n

One such source, the researchers postulated, is sulfur dioxide, a substance that can be ejected into the atmosphere during volcanic eruptions and which is found on many planets.<\/p>\n

Subjected to stellar radiation of sufficient power, molecules of sulfur dioxide could undergo double ionization, which may result in sulfur atoms breaking up, \u201cleaving behind a simple positively charged oxygen molecule O2+\u201d, a press release by the University of Gothenburg noted.<\/p>\n

That molecule can then be neutralized by receiving an electron from another molecule, thus resulting in the creation of abiotic O2.<\/p>\n

This mechanism may explain the presence of oxygen on apparently lifeless moons of Jupiter such as Io, Europa and Ganymede, the press release informed.<\/p>\n

\u201cWe also suggest in our article that this happens naturally on Earth,\u201d said Raimund Feifel, one of the authors of the new study.<\/p>\n

The researchers now seek to determine whether other molecules might behave in a similar way if subjected to double ionization.<\/p>\n

\u201cWe want to see if it also happens then, or if it was just a happy coincidence with sulfur dioxide,\u201d Feifel remarked.<\/p>\n
