JWST discovers ancient galaxy with complex organic molecules.
Astronomers using the James Webb Space Telescope (JWST) have discovered tangles of huge organic molecules drifting through a faraway galaxy, which suggests that their host galaxy was busy creating stars early in the history of the Universe. The galaxy lies 3.8 billion parsecs (12.3 billion light years) away, and the molecules are hard to spot except in infrared wavelengths of light, which JWST excels at studying. The discovery will force astronomers to rethink how dust first formed and how that shaped the early generations of stars and galaxies.
