DESCRIPTION
"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe. Most objects in the universe are so distant from us that we can only study them through light. Filters allow us to block some energy levels of light and isolate others; each energy of light can offer new information about the object of study. In "Filtered Light," participants discover how colored filters can help reveal more about an image. They can also make and study colorful images of their own.
