Researchers from the Max Planck Institute have uncovered something fascinating: the building blocks of life might be everywhere in space. Their study, published in The Astrophysical Journal, reveals over a dozen complex organic molecules swirling around a protostar in Orion. This suggests that these crucial chemicals can withstand the chaotic birth of stars, rather than waiting for a perfect planet to form.
Two significant organic molecules detected are ethylene glycol and glycolonitrile. These are important because they are precursors to DNA and RNA. Lead researcher Abubakar Fadul noted, “Our findings indicate a progression of chemical complexity from interstellar clouds to fully developed planetary systems.” So, it seems the seeds of life are already assembled in space, widely available.
Historically, scientists thought organic molecules would be destroyed during a star’s birth, which starts from a cold cloud of gas. During this tumultuous process, a protostar releases intense radiation and shockwaves that were believed to wipe the slate clean of any existing chemicals. The prevailing view held that molecules could only begin forming again once a suitable planet emerged.
But now, co-author Kamber Schwarz challenges that idea. “Our results suggest that these disks inherit complex molecules from earlier stages, and that complex molecules can keep forming during this time,” he said. This means that even amidst the chaos, the spark of life’s building blocks might persist.
Detecting these complex organic molecules isn’t easy, as they’re often trapped in icy dust grains. In the case of the V883 system, the young star is actively blowing out bursts of radiation, heating its surrounding disk. This release enables astronomers to spot the chemicals. The team used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, a powerful network of 66 antennas that worked together to capture these emissions.
Interestingly, the destructive nature of a young star may also help scatter these life-seeding molecules across space. If they can survive such a tumultuous environment, they have the potential to evolve chemically before planets form, making life’s origins in the universe even more possible.
Future observations may shed more light on this topic. Fadul hinted at exploring different parts of the electromagnetic spectrum to discover even more complex molecules. With each new finding, our understanding of life’s building blocks could shift significantly.
For those interested in deeper insights, a recent study by the National Aeronautics and Space Administration (NASA) highlights how organic molecules have been detected in various celestial bodies, emphasizing the possibility of life’s precursors being widespread in our universe.

As we continue to explore the cosmos, the potential for discovering the origins of life keeps expanding. Who knows what new revelations await us in the vastness of space?
