every time you get this new image it's
just like unwrapping a present to
basically see what there is to see
so it's a pretty exciting experience
but before we get the chance to
appreciate these mesmerizing images
they need to be tweaked
the human eyes can only see a very
narrow part of the spectrum you know
you're blue to red but there's light on
either of the other sides of that
spectrum and of course jwst is infrared
so it's on the red side of light right
so Webb is an infrared telescope so it's
sensitive to light that is beyond what
our eyes can see
so that's two layers of adjustments it's
the job of the data image developer
part science geek part artist to take
this invisible infrared light
translate it into colors our eyes can
see
jwst takes multiple images of the same
celestial object with different infrared
filters represented here in black and
white we've taken light of different
infrared wavelengths and split it up and
so there's long wavelength infrared
medium wavelengths a little bit shorter
and then shorter wavelengths now those
infrared waves are translated into the
colors of the rainbow we try to adhere
to a philosophy of colorizing the data
that we call chromatic ordering so we're
capturing these wavelengths in infrared
light and we're shifting them into the
visible part of the spectrum and we are
assigning colors that represent shorter
to longer wavelengths just like we would
see them
think of it like a song played on a
piano
transposed so we're hearing it in a
different key but it's still the same
song so the longest wavelength is going
to be red so I will make that red
the next longest wavelength I'll assign
that green
and then the shortest wavelength and
that'll be blue
in this case we actually have four
filters one of them is a narrow band
filter that is really isolating a very
specific kind of light
and that one we color orange
so after pulling everything together I
see that the initial color composite
image here and it's really interesting
that there's a lot of potential here but
I also see that it's very flat and it
needs some some compositional work
and then this where it kind of goes into
the subjective and more into the
artistic the Stars can look very
different
the quality of the nebula can look very
different there isn't really like a hard
point where it becomes you know going
from science to Art it's sort of the
whole process
the science is always there we're always
respecting the data
we're not trying to introduce things
that weren't there in the data to begin
with and we're not trying to remove
things that are there
so the whole goal of this is to create
an aesthetically pleasing image that
will capture someone's attention and
hopefully Inspire them to want to learn
more about this region in space
