  From life on other planets to virtual classrooms this thesis spans a wide
array of research topics all based on how we see other worlds. Our
understanding of everything from moon phases, the planets in our Solar System,
and exoplanet atmospheres come from our interpretation of light and one day,
our knowledge of light will be used as evidence for the discovery of life on
another planet.
  In the time before we scattered rovers, landers, and brave souls across the
Solar System we only knew of the planets and moons from the light they
reflected from the Sun back to us. We are in much the same situation with
exoplanets today. Our telescopes can gather the light from distant worlds but
they are too far out of reach to confirm our observations with in-situ
measurements. Soon we will be able to gather light from even smaller exoplanets
and eventually Earth-sized exoplanets orbiting in their star's habitable zone.
As a reference guide to these upcoming observations what better place to
compare to than our own Solar System. What we've done is take measurements of
planets in our own Solar System and treat them as exoplanets to determine how
different surface types can be differentiated. The result is a database of the
spectra, geometric albedos, and color of 19 Solar System objects for use as an
exoplanetary field guide.
  A step beyond the field guide is a way to explore worlds only physics and our
imaginations are limited by. By using computer models, we can create thousands
of planets to determine the physical and chemical stability of any environment.
One parameter domain of interest is the role of surface color on a planet's
habitability. Different materials have unique thermal properties that either
cool or heat a surface depending on their color and the light that hits them.
Dark oceans absorb light well and heat up while white sand is highly reflective
and keeps cool...
