Webb Detects The Universe’s Most Distant Complex Organic Molecules
Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth – the most distant galaxy in which these molecules are now known to […]
![Central panel: ammonia 14N/ 15N map in L1544. The contours show the total gas density at levels N(H2) = [1, 1.5, 2, 2.5] × 1022 cm−2 , obtained from Herschel SED fitting (Spezzano et al. 2017). The black circles show the three offsets (labelled with capital letters) where we compute average spectra to improve S/N. The averaged 15NH3 (1,1) lines are shown in the surrounding panels (black: observations, red: best-fit models, obtained as described in App. B). These panels are labelled in their top-left corner, whilst in the top-right corners we indicate the measured 14N/ 15N. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2023/06/Nitrogen.png?resize=1200%2C720&ssl=1)
