This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc, volatile gases are frozen out as ice, which contains complex organic molecules. An outburst of energy from the star heats the inner disc to a temperature that evaporates the ice and releases the complex molecules, enabling astronomers to detect it.
Now, astronomers have discovered 17 COMS in the planet-forming disc surrounding V883 Orionis. The team is particularly excited about two molecules: ethylene glycol and glycolonitrile, both important precursors to nucleic acids. The latter, glycolonitrile, is also a precursor to the nucleobase adenine and amino acids glycine and alanine.
The team, based at the Max Planck Institute for Astronomy , were able to identify “tentative” evidence for the presence of COMS such as ethylene glycol and glycolonitrile due to the radio frequencies the molecules emit. These signals, though faint, were collected by the Atacama Large Millimeter/submillimeter Array .
Instead, “Our finding points to a straight line of chemical enrichment and increasing complexity between interstellar clouds and fully evolved planetary systems,” lead author Abubakar Fadul explained in a
