However, Spilker says the implications of galactic smoke signals are much less disastrous for their cosmic ecosystems.

The data from Webb found the telltale signature of large organic molecules akin to smog and smoke -building blocks of the same cancer-causing hydrocarbon emissions on Earth that are key contributors to atmospheric pollution. “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.” and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy. “By combining Webb’s amazing capabilities with a natural ‘cosmic magnifying glass,’ we were able to see even more detail than we otherwise could,” said Spilker, an assistant professor in the Texas A&M Department of Physics and Astronomy and a member of the George P. The light from the background galaxy is stretched and magnified by the foreground galaxy into a ring-like shape, known as an Einstein ring. Lensing, originally predicted by Albert Einstein’s theory of relativity, happens when two galaxies are almost perfectly aligned from our point of view on Earth. Spilker notes the discovery, reported this week in the journal Nature, was made possible through the combined powers of Webb and fate, with a little help from a phenomenon called gravitational lensing. The galaxy was first discovered by the National Science Foundation’s South Pole Telescope in 2013 and has since been studied by many observatories, including the radio telescope ALMA and the Hubble Space Telescope. Because of its extreme distance, the light detected by the astronomers began its journey when the universe was less than 1.5 billion years old - about 10% of its current age. Using the Webb telescope, Texas A&M University astronomer Justin Spilker and collaborators found the organic molecules in a galaxy more than 12 billion light-years away. At least for galaxies, the new findings cast doubt on the old adage that where there’s smoke, there’s fire. The discovery of the molecules, which are familiar on Earth in smoke, soot and smog, demonstrates the power of Webb to help understand the complex chemistry that goes hand-in-hand with the birth of new stars even in the earliest periods of the universe’s history.
