1. Illustration of Absorption by Intergalactic Gas
In this artist's rendition, X-rays from a distant quasar traveling toward Earth and the Chandra X-ray Observatory are shown as waves of colored light. As they pass through a cloud of intergalactic gas, which appears as the white, filamentary structure, some of the X-rays are absorbed. (Illustration: SAO/CXC/A.Hobart)
