Scientists found Halley's Comet ejected traces of molecular oxygen during the ESA's Giotto probe in 1986, suggesting that O2 is common in other comets in the solar system.
Space December 11, 2015
The European Space Agency's Rosetta spacecraft has detected traces of molecular oxygen on the 67P/Churyumov-Gerasimenko comet. Scientists are now trying to determine how the gas was formed on the comet when earlier theories suggest that it should have been annihilated during the formation of the solar system.
