In
this
interactive
web
game,
participants
learn
about
the
different
types
of
galaxies
(spiral,
elliptical
and
irregular)
by
viewing
them
in
different
wavelength
bands
(infrared,
visible,
x-ray).
They
then
learn
about
active
galaxies
vs.
quiescent
galaxies
by
examining
visible
light
spectra
together
with
the
multi-wavelength
images.
The
final
challenge
is
to
observe
a
model
of
our
own

This
site
describes
snow
crystals
and
snowflakes.
Although
a
common
meteorological
phenomenon,
snow
crystal
growth
is
a
fascinating
and
poorly
understood
process,
in
which
remarkably
complex
and
beautifully
symmetric
structures
appear,
quite
literally,
out
of
thin
air.
The
many
facets
of
snow
crystals
are
described
here,
along
with
the
attempts
to
understand
their
formation.
