Presents information from the big bang to the end of the universe.

MAP is a MIDEX class mission, selected by NASA in 1996, to probe conditions in the early universe. MAP measures temperature differences ("anisotropy") in the cosmic microwave background radiation.

An illustrated introductory guide to the topic, attempting to summarize modern discoveries on the origin, current state, and future of the Universe.

Extensive CMB information from the University of British Columbia.

A dedicated 2.5 meter telescope which uses sensitive electronic light detectors to systematically map a quarter of the sky, building a catalog of celestial objects, galaxies, and quasars.

Primary aim is to test the hypothesis that a significant fraction of the dark matter in the halo of the Milky Way is made up of objects like brown dwarfs or planets: these objects have come to be known as MACHOs, for MAssive Compact Halo Objects.

Following in the footsteps of the famous April 1920 'Great Debate' between Harlow Shapley and Heber Curtis, this series of debates among leaders in the astronomical community highlight major quests in astronomy and astrophysics in an open forum at the turn of the millennium.

This Berkeley labs site is based on observation of red shift in stars going supernova.

A series of scientic experiments flying as balloon payloads in Texas and Antarctica, designed to measure the medium-scale anisotropy of the cosmic microwave background radiation (CMBR).

Companion site to the PBS mini-series, discussing the challenge to traditional Christian views posed by the scientific understanding of cosmological evolution, and ways in which they might be reconciled.

Dedicated to summarizing the research of Paul Shapiro's cosmology group. Of interest mainly to specialists.
