These days, scientists think they have a pretty good idea of
what the universe is made of. By detecting the telltale signatures
of various elements in celestial bodies like stars, asteroids, and
other planets, scientists can estimate how abundant or rare each of
the known elements is. Iron, however, has proven to be tricky to
nail down.

We know iron is abundant on Earth as well as in stars, where the
intense heat allows it to exist in the form of gas. That suggests
that the element should also exist in relative abundance in the
interstellar medium — the space between star systems in galaxies
such as the Milky Way — but scientists haven’t detected much of
it there. So, where is it? A new study published in the Astrophysical
Journal
might have the answer.
