You
may
think
there's
not
much
of
anything
in
between
the
stars,
but
of
course
you
would
be
wrong.
We
speak
of
an
interstellar
medium
,
full
of
interesting
atoms,
molecules,
and
dust
grains.
The
study
of
the
atoms
and
molecules
found
in
interstellar
space
is
essential
to
the
understanding
of
how
stars
are
born,
how
they
live,
and
how
they
die.
Let’s
take
a
look
at
a
few
of
the
more
visually interesting emission nebulae
.
Here are just a few of the broad categories of objects found out between the stars of our galaxy.
•
Hydrogen Clouds
•
