Scientists have discovered a large polycyclic aromatic hydrocarbon called cyanocoronene in deep space, indicating that complex organic molecules necessary for life can form even before stars are born, which could have significant implications for understanding the origins of life in the universe.
Scientists have discovered the largest aromatic molecule, cyanocoronene, in interstellar space within the Taurus molecular cloud, doubling the size of previous records and suggesting complex organic chemistry occurs even before star formation, with implications for understanding the origins of organic molecules in the universe.
A study using JWST data reveals that closed-shell polycyclic aromatic hydrocarbons (PAHs) in space survive extreme conditions through a mechanism called recurrent fluorescence, which efficiently dissipates excess energy and explains their abundance in interstellar clouds.
Recent research has revealed that polycyclic aromatic hydrocarbons (PAHs), organic molecules considered as prebiotic building blocks for life, can form in the cold regions of space with temperatures around 100 K, challenging the previous belief that they only formed in warmer environments near stars. This discovery, made through the study of asteroid Ryugu and the Murchison meteorite, suggests that these molecules predate the Solar System and opens up new pathways for understanding the chemical evolution of life on Earth and potentially other celestial bodies.
Astronomers have discovered the most distant organic molecules in the universe using the James Webb Space Telescope. The molecules, called polycyclic aromatic hydrocarbons (PAHs), are considered the basic building blocks for early forms of life. The discovery was made in a galaxy more than 12 billion light years from Earth, and the light used to make the observation likely began traveling when the universe was less than 1.5 billion years old. The researchers used gravitational lensing and the James Webb telescope's sensitive instruments to differentiate between infrared signals produced by larger dust particles and those produced by PAHs.
