Basic introduction to modern cosmology, aimed at a general audience. This NASA site is part of the outreach efforts for the WMAP space probe, which measures an "Echo of the Big Bang": the cosmic microwave background radiation.

Article from Christian Science Monitor about Paul Steinhardt and his work on the "Ekpyrotic Universe", a speculative model which uses concepts of string theory to arrive at a periodically repeating series of big bangs.

Companion website to the PBS-Thirteen/WNET six-part series of the same name. Includes information about many facets of cosmology and the researchers involved, as well as a Teacher's Guide.

A fairly complete overview of current cosmological models, from the cosmological principle to cosmic expansion and the physics of the early universe. Uses very simple formulas.

Companion website for a PBS NOVA program originally broadcast in 2000, which examines the size, future and fate of the universe. Contains background material on mapping the universe, supernovae as standard candles, and a virtual tour of the universe.

Site maintained by a UCLA astronomy professor, which features an introduction to cosmology (which uses no more than high-school level mathematics), links to resources, a section on "fads and fallacies", and comments on latest developments.

Extensive collection of articles, monographs, data bases, tools and essays related to extragalactic astronomy and cosmology. Maintained by Barry F. Madore (Caltech and Carnegie Observatory).

Lecture notes by David H. Lyth (Lancaster University), with a special emphasis on large scale structure, the anisotropies of the cosmic microwave radiation, and inflation. Presupposes basic knowledge of physics at an undergraduate level, as well as some familiarity with particle physics.

Condensed lecture notes at graduate-student level on standard cosmology, the physics of the early universe, and inflation. Based on lectures given by G. Lazarides (Aristotle University of Thessaloniki) at the 1998 Corfu Summer Institute on Elementary Particle Physics.

Companion site to the PBS mini-series "Faith & Reason". The cosmology section discusses the challenge to traditional Christian views posed by the scientific understanding of cosmological evolution, and ways in which they might be reconciled.

Online book from the National Academy of Sciences, published in 1995 by the National Research Council's Board on Cosmology as a re-assessment of the cosmological research earlier examined by the Physics Survey Committee. Includes chapters on the cosmic background radiation, the large scale structure of universe, and the physics of the early universe.

Overview of cosmology, suitable for a general audience, from Patricia Schwarz's Official String Theory Website. Includes information on big bang models, inflation, and, naturally, on the connection between cosmology and string theory.

Entry in Eric Weisstein's World of Physics. Contains many links to related entries, and a list of useful materials.

Collection of articles about various aspects of cosmology, from the physics of the big bang phase to the shape of the universe. Part of the "Spotlights on Relativity" series on Einstein Online; written for a general audience.

Lecture notes for graduate-level lectures originally given at the 1998 Cargese summer school, by George Ellis and Henk van Elst. The notes give a systematic presentation of a 1+3 covariant approach to studying the geometry, dynamics, and observational properties of the cosmological models of general relativity.

Webpages created by the Cambridge University cosmology group for a general audience, with information about black holes, the big bang models, cosmic strings, galaxies and galaxy clusters, and inflation.
