论文摘要
从其他行星上的生活到虚拟教室，这一论文涵盖了许多基于我们如何看待其他世界的研究主题。我们对月阶段，太阳系中的行星以及系外行星气氛的所有理解来自我们对光线和一天的解释，我们对光线的了解将被用作在另一个星球上发现生命的证据。 在我们散布漫游者，兰德斯和勇敢的灵魂之前，我们只知道他们从太阳从太阳回到我们身边的光线和卫星。今天，我们与系系相同的情况。我们的望远镜可以从遥远的世界中收集光线，但它们太远了，无法通过原位测量来确认我们的观察结果。不久，我们将能够从较小的系外行星中收集光，并最终在其恒星的宜居区中绕着地球大小的系外行星。作为对这些即将到来的观察的参考指南，比我们自己的太阳系更好地比较了。我们所做的是对自己的太阳系中的行星进行测量，并将其视为系外行星，以确定如何区分不同的表面类型。结果是光谱，几何反照率和19个太阳系对象的颜色的数据库，以用作系型野外指南。 超越现场指南的一步是探索世界物理学的一种方法，我们的想象力受到限制。通过使用计算机模型，我们可以创建数千个行星来确定任何环境的物理和化学稳定性。感兴趣的一个参数域是表面颜色在行星宜居性中的作用。不同的材料具有独特的热能性能，可以根据其颜色和击中其光冷却或加热表面。黑暗的海洋可以很好地吸收光线并加热，而白色的沙子高度反射并保持凉爽...
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...
