Dr. 雷切尔·史密斯是一位观测天文学家，对我们的太阳系和其他行星系统如何随着时间的推移形成和演变感兴趣. 她使用了一些最大的地面光学红外望远镜, including the 10-meter Keck Observatory on Mauna Kea in Hawaii, to study the chemistry of protoplanetary material — the gas, ice, 以及最终构成行星和生命前化合物的尘埃，这些尘埃围绕着银河系中正在形成的恒星. Dr. 史密斯使用Keck II望远镜上的高分辨率光谱仪NIRSPEC来详细评估一氧化碳气体（CO）中碳和氧的同位素, the same molecule in car exhaust). This gas is abundant in protoplanetary systems, 其中许多类似于我们太阳系形成时的情形.57 billion years ago.
Dr. 史密斯与加州理工学院的科学家合作, Jet Propulsion Laboratory, Space Telescope Science Institute, NASA Ames, and the American Museum of Natural History.
从这些观测得到的数据可以与陨石和太阳相比较, 这是我们从早期太阳系中获得的最古老的物质——为了了解早期形成行星的基本化学途径, and eventually, life.
Dr. 史密斯目前正在分析一个来自比太阳质量更大的年轻恒星的大型数据集，以便更多地了解恒星和行星形成在银河系不同环境下的变化. 她最近还参加了平流层红外天文观测站，作为一个旨在观察大质量年轻恒星中二氧化硫的项目的一部分.
Dr. 史密斯负责管理博物馆的陨石收藏. She is currently working on building the collection, examining meteorites in thin section, as well as exploring other visualization tools.
View Meteorite Collection Database.
Additionally, she oversees the visual content of the Astronomy & Astrophysics Research Lab (AARL), 目前是一个令人兴奋的项目的一部分，该项目使用名为“开放空间”的新开源宇宙飞行软件来创建交互式节目和数字内容. 该软件的开发是美国宇航局与纽约市美国自然历史博物馆合作的一部分, and also includes other museum and institutional partners.
Dr. 史密斯教授两门本科课程，她也为阿巴拉契亚州立大学开发：天体生物学：探索宇宙中的生命（春季/秋季交替学期）, and Star Formation (alternating fall semesters). 这些课程有助于介绍天体物理学和太空探索的核心基本概念, and the many facets of searching for life beyond Earth. Dr. 每年夏天，史密斯都会为有兴趣加入她的研究和/或推广项目的本科生提供几个实习机会.
Courses Taught at Appalachian State University:
- 天体生物学：在宇宙中寻找生命（春季/秋季交替）
- Star Formation (Alternating Fall)
