Antarctica provides a unique environment for astronomy. The cold, dry and stable air found above the high plateau, as well as the pure ice below, offers new opportunities across the photon & particle spectrum. The summits of the plateau provide the best seeing conditions, the darkest skies and the most transparent atmosphere of any earth-based observing site. Astronomical activities are now underway at four plateau sites: the Amundsen-Scott South Pole Station, Concordia Station at Dome C, Kunlun Station at Dome A and Fuji Station at Dome F, in addition to long duration ballooning from the coastal station of McMurdo. Astronomy conducted includes optical, IR, THz & sub-mm, measurements of the CMBR, solar, as well as high energy astrophysics involving measurement of cosmic rays, gamma rays and neutrinos. Antarctica is also the richest source of meteorites on our planet. An extensive range of site testing measurements have been made over the high plateau. We summarise the facets of Antarctica that are driving developments in astronomy, and review the results of the site testing experiments undertaken to quantify those characteristics of the plateau relevant for it pursuit. We outline the historical development of the astronomy on the continent, and then review the principal scientific results to have emerged over the past three decades of activity in the discipline. We discuss how science is conducted in Antarctica, and in particular the difficulties, as well as the advantages, faced by astronomers seeking to bring their experiments there. We also review some of the political issues that will be encountered, both at national and international level. Finally, we discuss where Antarctic astronomy may be heading in the coming decade, in particular plans for IR & THz astronomy, including new facilities being considered for these wavebands at high plateau stations. : Review paper on the field of Astronomy in Antarctica, for publication in The Astronomy and Astrophysics Review. 52 pages, 22 figures
