(Phys.org)--A team of researchers, encouraged by the latest discovery of ESA's Rosetta spacecraft of molecular oxygen (O2) on the comet 67P/Churyumov-Gerasimenko, are going over comet 1P/Halley (known as Halley's Comet) with a fine-tooth comb, searching for the traces of this essential molecule. The new study, led by Martin Rubin of the University of Bern, Switzerland, shows that molecular oxygen is also present on 1P/Halley and therefore might be common on other comets.
