Harlan Smith, chairman of the University of Texas's Astronomy Department, discusses a mobile lunar laser ranging station which could help determine the exact rates of movement between continents and help geophysicists understand earthquakes. He also discusses its application for studying fundamental concepts of cosmology and physics. (Editor/RK)

Discusses the embargo hypothesis--the theory that Earth is apparently free from alien exploitation because of a presumed cosmic quarantine against this planet--which implies that, instead of being only a few hundred years technologically in advance of earthly civilization, extraterrestrials in charge are likely tens of thousands of years in…

Describes the major components of the solar system and proposes several features that a theory about the solar system should include. Contains explanations of several theories about the origin of the solar system. (TW)

This bibliographic essay evaluates six books on Halley's Comet as science writings that fall into three categories: middle school and junior high-level books; senior high to adult-level books; and advanced level. Author, number of pages, publication date, price, International Standard Book Number, and publisher information are provided. (EJS)

This exploratory study determined whether a mathematical model of mastery learning provided a good fit for achievement data obtained from student progress in an introductory, college-level astronomy course for nonmajors. Results provide positive but not compelling evidence that the model of mastery learning is correct. (JN)

Presents a technique for obtaining a rough measure of the brightness among different stars. Materials needed include a standard 35-mm camera, a plastic ruler, and a photo enlarger. Although a telescope can be used, it is not essential. (JN)

In preparation for the Voyager flybys in 1989, the pace of ground-based investigations of the moons of Uranus, Neptune, and Pluto has quickened considerably. Information derived from these investigations is presented. (JN)

Highlights major accomplishments and developments in various disciplines during 1984. These disciplines include: genetics; medicine; the biosciences; astronomy; evolution; the geosciences; behavior; physics; chemistry; the environment; mathematics; and the space sciences. (JN)

Presents a selection from a revised and updated version of "The Red Limit" by Timothy Ferris. The book is a completely nontechnical introduction to 20th century cosmology, the study of the large-scale properties of the universe. (JN)

Reviews a six-part series (available as 16mm film or videocassettes) in which actors portray scientists lecturing on various topics/issues.
