Webb spots a building block of life on Jupiter`s moon Europa
-----------------------------------
Organic compounds were thought to be fundamentally different from man-made
ones until this experiment in 1828:

"Before this experiment, most investigators believed that a "life force"
motivated or influenced all substances found in
plants and animals. They therefore contended that any substance produced by
a life process could not be made
from inorganic chemicals."
The classification "organic" stuck although it now means both natural and
synthetic carbon compounds.
In 1952 this experiment showed that electricity could create the building
blocks of proteins from cosmically abundant simple gases:

"Most of the natural amino acids, hydroxyacids, purines, pyrimidines, and
sugars have been made in variants of the Miller experiment."
Electricity separates molecules into smaller reactive parts (radicals) that
recombine with whatever they randomly encounter. Like seeing shapes in
clouds almost anything is possible, chemical thermodynamics is a study of
the probability.
Detecting organic molecules in the absorption spectra of celestial objects
is very far from an indication of life. It seems the media isn`t yet up to
date on what chemists learned almost 200 years ago.
