This visually-engaging eBook takes a deep dive into the history and science of ultraviolet (UV) astronomy. Astrophysicists find that UV data are of considerable use when they want to study many of the phenomena that occur in distant galaxies, which are often associated with massive black holes at the centers of galaxies. This eBook describes a variety of discoveries in UV astronomy made by space-based observatories since the beginning of the Space Age up to the present day. Ultraviolet Astronomy features notable missions in UV astronomy such as the International Ultraviolet Explorer (IUE), and specialized astronomical observations involving the Wide Field Camera 3 of NASA’s Hubble Space Telescope.
