NASA's Chandra X-ray Observatory uses binary code to gather information about Earth's surface. That code, in the form of two numbers (1s and 0s), is then read and converted by computers into images. This two-page handout provides background about Chandra and an explanation of binary code. It also includes a chart showing the binary equivalent of uppercase and lowercase English language alphabet characters. The chart can be used by students to decode or write words using binary data.
