The light we see with our eyes only tells a small part of the Universe's story. To get a complete picture of how the Universe works, astronomers must study objects over the full range of light, the electromagnetic spectrum. This includes gamma rays, X-rays, ultraviolet, visible, infrared, micro- waves and radio waves. Each type of light requires different instruments, and provides unique information about the source that emitted it. Dr. Mulchaey will explain how Carnegie astronomers and their colleagues are combining observations across the electromagnetic spectrum to help solve the mysteries of the Universe.
