An article published in the journal “Nature Astronomy” reports a study on the interstellar comet 2I/Borisov focused in particular on its chemical composition which highlights the abundance of carbon monoxide and hydrogen cyanide. A team of researchers led by Martin Cordiner and Stefanie Milam of NASA’s Goddard Space Flight Center used the ALMA radio telescope to examine the comet’s emissions detecting that carbon monoxide is present in its coma in an amount that is between 9 and 26 times that estimated for the solar system’s comets. This suggests that it formed in a very cold area of ​​its origin system.
