A Cosmic Chemical Breakthrough: Astronomers Discover New Building Blocks for Complex Organic Matter

National Radio Astronomy Observatory — Thu, 24 Oct 2024 14:00:00 EST

The element carbon is a building block for life, both on Earth and potentially elsewhere in the vast reaches of space. There should be a lot of carbon in space, but surprisingly, it's not always easy to find. While it can be observed in many places, it doesn't add up to the volume astronomers would expect to see. The discovery of a new, complex molecule (1-cyanopyrene), challenges these expectations, about where the building blocks for carbon are found, and how they evolve. This research was published today in the journal Science.
