Astronomers have detected the most distant known organic molecules in the universe using the James Webb Space Telescope. It’s the first time Webb has detected complex molecules in the distant universe.
The complex molecules were found in a galaxy known as SPT0418-47, located more than 12 billion light-years away. The discovery sheds light on the chemical interactions that occurred within the earliest galaxies in the universe and how they relate to star formation. On Earth, the molecules, called polycyclic aromatic hydrocarbons, can be found in smoke, soot, smog, engine exhaust and forest fires.
“That level of magnification is actually what made us interested in looking at this galaxy with Webb in the first place, because it really lets us see all the rich details of what makes up a galaxy in the early universe that we could never do otherwise,” said Spilker, who is also a member of Texas A&M’s George P. and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy.
