Astronomers have discovered key components of life’s building blocks swirling around remote baby stars, suggesting that life’s stuff is much more common than once thought.
The material that swirls the 1,300 light-year-old Protostal V883 Orionis from Earth in the constellation Orion is made up of 17 complex organic molecules, including ethylene glycol and glycolonitrile.
The discovery, published July 23rd in The Astrophysical Journal Letters, could encourage scientists to rethink how common chemical pioneers are. Similar compounds have been discovered elsewhere in the universe, but astronomers have previously assumed that many of these will be destroyed by the violent birth of stars, and only rare planetary systems capable of breeding them are scattered with seeds of life.

In a statement, Kamber Schwarz, co-author of the study, an astrochemist at the Max Planck Institute for Astronomy in Heidelberg, Germany, said in a statement. “Our results suggest that protoplanetary discs inherit complex molecules from previous stages, and that complex molecule formation can continue at the protoplanetary disc stage.”
Scientists have long tracked the fundamental chemicals of the origin of life across space. So far, this search has produced molecules in front of comets, asteroids, and comets floating in gases and dust in interstellar space.
The stars start with clouds of gas and dust. The stars slowly collapse and heat up, and eventually form a protos and prototar and protonatera discs comets, asteroids and planets. However, this process is a violent process, with the shocked gas and intense star radiation efflux producing enough energy to destroy and reset the stable chemical concentration that leads to complex organic molecules.

Or that’s what scientists think. Using Atacama’s Large Millimeter/Sub-Millimeter Array (ALMA), a collection of 66 wireless telescopes in northern Chile, the scientists behind the new study discovered a Telltail emission line from clusters of organic molecules within the protozoa of V883 Orionis. The young star is still screaming at its nucleus of fusion fire, leading to a powerful burst of radiation.
“These explosions are strong enough to heat the surrounding disks into an ice-like environment to release any chemicals we detect,” Abubakar Fadul, a graduate student at the Max Planck Institute for Astronomy Institute, said in a statement.
This means that instead of destroying these organic compounds, the growth of stars may release them from the ice surface where they normally form, referring to “the increasing complexity between the linear lines of chemical enrichment and interstellar clouds and fully evolved planetary systems.”
The results are exciting, but scientists warned that they will remain tentative. Researchers should obtain high-resolution data to confirm detection and conduct in-depth research into how well these compounds are retained as the host stars grow.
“Perhaps we’ll need to look into other regions of the electromagnetic spectrum to find more advanced molecules,” Fadur said. “Who knows what else we will discover?”
