Astronomers have identified a new organic molecule, 1-cyanopyrene in interstellar space. This finding gives insights into how carbon-rich compounds form and survive in these regions.
Carbon is important for life on Earth and its presence in space has been a key area of research.
Scientists believe that carbon-rich stars release small carbon molecules that could not endure the harsh conditions of interstellar space.
But, researchers from the Center for Astrophysics | Harvard and Smithsonian (CfA) have challenge this view.
The study, publish in Science, suggests that these molecules can exist and evolve even in extreme environments.
Bryan Changala, a co-author of the study, highlight the importance of this discovery.
Bryan Changala said :
“Our detection of 1-cyanopyrene gives us important new information about the chemical origin and fate of carbon,”.
1-cyanopyrene is part of the Polycyclic Aromatic Hydrocarbon (PAH) family.
As before, PAHs were thought to form only in high-energy environments around aging stars.
They can be find in products like burning fossil fuels on Earth.
In space, studying PAHs helps astronomers understand their life cycles and their role in the interstellar medium.
The molecule was detect in the Taurus Molecular Cloud-1 (TMC-1), a cold interstellar cloud where temperatures are just above absolute zero.
Gabi Wenzel, a postdoctoral fellow at MIT, said that TMC-1 serves as a natural laboratory for studying molecules that contribute to star and planet formation.
The NSF Green Bank Telescope facilitate this discovery by helping researchers identify 1-cyanopyrene through its unique rotational spectrum.
The study showcases the collaboration of chemists, astronomers and modelers in understanding complex molecules in space.
