https://www.livescience.com/space/cosmology/scientists-find-ultra-rare-collection-of-molecules-in-2-ancient-galaxies-from-the-early-universeA treasure trove of molecules has turned up in
two galaxies that we see as they were over
12 billion years ago, revealing information
about how the ancient realms form stars.
...
Among the 13 different types of molecules
detected are carbon monoxide, carbon monosulfide,
the cyano radical (a radical is a molecule with
an unpaired electron in the outer shell of one
of its constituent atoms), the formyl cation (a
cation is positively charged ion), hydrogen
cyanide, hydrogen isocyanide, nitric oxide and
water. Yang's team also detected five molecules
that haven't been seen before in the early
universe: Cyclopropenylidene (a highly reactive
organic molecule also found on Saturn's moon
Titan), diazenylium (formed of molecular
nitrogen and a hydrogen ion), radicals of the
organic molecule ethynyl, hydronium ions
(formed from a water molecule and a hydrogen
ion) and radicals of methylidyne (a highly
reactive organic molecule).
All of these molecules are commonly found in
interstellar gas in our Milky Way galaxy, and
each provides clues about the environment in
which they are found in — an environment we see
forming lots of stars.
