Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object, co-developed between NASA and NSTA, is the first of five Science Objects in the Universe SciPack. It explores the methods and tools used by astronomers to study the universe and the various objects that make up the known universe. What we know about the universe today is a result of increasingly sophisticated technologies that allow astronomers to capture and study incoming light from the universe across many different wavelengths of the electromagnetic spectrum, as well as use computers to analyze data. Astronomers study the position and motion of objects, as well as the color and intensity of the light coming from those objects. These observations help determine the distances of those objects, their composition, and the processes at work.
