The National Aeronautics and Space Administration (NASA) achieved a groundbreaking advancement in their quest to find signs of life in the universe. They discovered a carbon molecule that is believed to be the fundamental building block for all known life.
The James Webb Space Telescope, operated by NASA, was responsible for this significant breakthrough in detecting carbon molecules in space. In a recent website post, NASA revealed that a team of international scientists used the telescope to identify a new carbon compound called methyl cation (CH3+). This molecule plays a crucial role in the formation of more complex carbon-based molecules. The detection of methyl cation occurred in a young star system called d203-506, located approximately 1,350 light-years away in the Orion Nebula.
NASA emphasized the importance of carbon compounds in the foundation of all known life forms. The discovery of these molecules is of particular interest to scientists seeking to understand the origins of life on Earth and the possibility of life in other parts of the universe. The study of interstellar organic chemistry has captivated astronomers, and the James Webb Telescope’s capabilities have opened up new avenues for exploration in this field.
The James Webb Telescope’s unique features, including its exceptional spatial and spectral resolution and sensitivity, contributed to the successful detection of CH3+. The telescope’s ability to capture key emission lines from the molecule solidified the discovery.
Marie-Aline Martin-Drumel, a professor at the University of Paris-Saclay and a member of the science team, emphasized that this discovery not only confirms the remarkable sensitivity of the Webb telescope but also underscores the presumed central importance of CH3+ in interstellar chemistry.
Although the star in the d203-506 system is a small red dwarf, it is exposed to intense ultraviolet (UV) radiation from nearby hot, young, massive stars. Scientists believe that most planet-forming disks experience a period of such intense UV radiation since stars often form in groups that include UV-producing stars. Typically, complex organic molecules are destroyed by UV radiation, making the discovery of CH3+ a significant achievement.
Interestingly, the team hypothesizes that UV radiation might actually provide the necessary energy for the formation of CH3+. Once formed, CH3+ promotes additional chemical reactions that lead to the development of more intricate carbon molecules. The researchers note that the molecules observed in d203-506 differ from those typically found in protoplanetary disks, and they could not detect any signs of water in this particular system.
