Includes summary data, observing tips, and images. By Dennis Webb. - Provides an introduction to the classification of galaxies into spiral, barred spiral, elliptical, irregular, lenticular and radio galaxies. - Determining the distances to nearby galaxies. - HST and ISO Results. - Some useful information about the formation of galaxies. - Galaxies with their descriptions. - Includes a set of notes by Nick Strobel. Topics include the structure of the Milky Way, the characteristics of other galaxies, and finding distances to other galaxies. - Many selected links to websites dedicated to galaxies. - NASA Windows to the Universe. Includes illustrations and introductory information about a variety of galaxies. - Contains information of the types, dynamics, observations, and formation of galaxies. - A review article for non-specialists. - Contains information about the growth of various galaxies. Also includes images, news, and a glossary. - Wikipedia article about the several schemes in use by which galaxies can be classified. - Data, observation notes, and more about globular clusters within the galaxy. - Project at Lawrence Berkeley National Lab to search for supernovas in very remote galaxies. This provides an accurate means of measuring the distances to remote galaxies and thereby determining the age of the universe. - Classifications, properties, and structures and dynamics. - Includes a catalog of globular clusters, photos, and brief description. - Research group at the Ludwig-Maximilians-University Observatory studying the structure and evolution of galaxies, especially stellar dynamics, stellar populations and galaxy formation from the point of view of optical and near-infrared astronomy. - A collection of hundreds of review articles. Topics covered include normal, peculiar and interacting galaxies, as well as galaxy evolution and galaxy clusters. Part of Caltech's "LEVEL 5" knowledgebase of extragalactic astronomy and cosmology. - Java-based viewing tool that allows the user to view galaxy surveys such as the Hubble Deep Field, using their browser. - Spiral galaxies with short descriptions and photos. - Gives mathematical measurements relating this galaxy that orbits the Milky Way. Includes history about first known discoveries and links to photo galleries. - Research group primarily interested in high energy activities in galaxies, particularly the interplay between massive stars and the interstellar medium.
