The Timbie Group at the University of Wisconsin-Madison specializes "in the development and deployment of instruments capable of reaching the exquisite levels of sensitivity necessary to detect the very weak microwave signals constituting the Cosmic Microwave Background" (CMB). The website offers materials about the group's current and recent endeavors, including the Polarization Observations of...

Readers from a variety of backgrounds may enjoy Origins, an award-winning multimedia site published by the University of Wisconsin-Madison in April 2018. Created with general audiences in mind, this engaging and highly visual project focuses on three different aspects of "the quest to understand our beginnings -- of our universe, of life on Earth, of our species," through the university's research...

The Annenberg Media organization has created this wonderful new resource for physics teachers, students, and anyone else who would care to learn more about dark matter, string theory, and other "big topics in modern physics". Produced by the Harvard-Smithsonian Center for Astrophysics Science Media group along with the Harvard University Department of Physics, this 11-part course features 22 case...

The University of California Los Angeles Division of Astronomy and Astrophysics professor Edward Wright maintains the Relativity Tutorial Web site. The site explains the history and general concepts behind relativity. Subjects covered include special relativity, radar, time dilation, general relativity, the principle of equivalence, curved spacetime, and how relativity is important to cosmology....

This Web site contains the virtual version of ScienceTunnel, a museum exhibit currently at the Museum of Science and Industry in Manchester, England. Created by the Max-Planck-Society, ScienceTunnel invites visitors to "travel through the dimensions of this world and onward to the outskirts of our knowledge." Visitors explore twelve orders of magnitude, from the composition of subatomic particles...

This pre-print from the Stanford Linear Accelerator Center (SLAC) covers string theory and dark matter, in particular the baryon/ photon ratio at the time of nucleogenesis. The theories presented are not in disagreement with actual cosmological data, including that from BOOMERANG. This pre-print may be downloaded for free in .pdf or .ps format.

Simeon De Witt's star map has a long and curious history dating all the way back to its completion in 1780. De Witt was a surveyor for George Washington and the Continental Army, and this highly detailed map shows the stars visible from his post in New Jersey. De Witt later said that his work and the time he spent outside watching the stars gave him an appreciation of "the ever shifting scenery of...

This UC-Davis web site promotes its cosmology research, investigators, and related events. Users can find links to the group's four main research projects: Deep Lens Survey, The Great Observatories Origins Deep Survey (GOODS), the proposed development of the Large Synoptic Survey Telescope (LSST), and Faint Images of the Radio Sky at Twenty - cm (FIRST). The site offers extensive descriptions and...

NASA's Wilkinson Microwave Anisotropy Probe mission attempts to reveal conditions as they existed in the early universe by measuring the properties of the cosmic microwave background radiation over the full sky. Visitors can learn more about the particulars of the mission, explore the subjects of cosmology and the "Big Bang Theory" on the Universe link, view images of the probe and its launch in...
