Astronomers using the James Webb Space Telescope discovered evidence of complex organic molecules in a galaxy 12.3 billion light-years away — the furthest and oldest ever detected.
Scientists using the James Webb Space Telescope have spotted a cloud of complicated organic molecules in a galaxy 12.3 billion light-years away — the farthest from Earth that molecules of this kind have ever been detected. The discovery, which was published on June 5 in the journal Nature, might help astronomers piece together a clearer picture of how galaxies develop.
The complex molecules in question are called polycyclic aromatic hydrocarbons . On Earth, PAHs are commonly found in wildfire smoke and car exhaust. In space, they might play a crucial role in star formation. Scientists suspect that they help regulate the temperature of gas clouds in stellar nurseries, thereby managing when and where stars develop, Nature reported.
The team studied this light, and their initial analysis indicated that SPT0418-47 was rich in heavy elements. But the scientists couldn't get a good look at its organic, carbon-containing components using the South Pole Telescope, which doesn't pick up the right wavelength of light.

Early universe crackled with bursts of star formation, Webb Telescope showsAmong the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA's James Webb Space Telescope is already providing new insights into this question. One of the largest programs in Webb's first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will devote about 32 days of telescope time to uncover and characterize faint, distant galaxies. While the data is still coming in, JADES already has discovered hundreds of galaxies that existed when the universe was less than 600 million years old. The team also has identified galaxies sparkling with a multitude of young, hot stars.
