Presents a chapter from an introductory college-level astronomy textbook in which full-color photographs and numerous diagrams highlight an extensive description of the planet Jupiter. Topics include Jupiter's geology, rotation, magnetic field, atmosphere (including clouds and winds), and the Great Red Spot. (DH)

This article reviews the historical and current observational status of searches for other planetary systems, discusses the nature of the observational problem, and indicates the prospects for success in the future. (DS)

Describes a course, without laboratory, using rudimentary algebra and covering such topics as gravitation, orbital mechanics, atomic structure, geomagnetism, electromagnetic spectrum, theory of relativity, extraterrestrial life, and interstellar travel. (GH)

Describes a dynamical system which is stable at potential maxima. The maxima, called L-4 and L-5, are stable locations of the restricted three-body problem. Energy loss from the system will tend to drive it away from stability. (GA)

Various aspects of the solar sail spacecraft such as solar sailing, solar sail design, navigation with solar sails, solar sail mission applications and future prospects for solar sailing are described. Several possible student projects are suggested. (KR)

Presents a theory concerning the orbital spacing of patterns in the solar system. The orbital distributions of the planets and major satellite systems are fitted with a Bode-type form. Accordingly, the Saturnian system requires vacant orbitals if the best fit is to have an accuracy comparable to that of other systems. (Author/GA)

A series of 12 reports on the Voyager Two experiments in the Uranian system. Reports are included on: (1) imaging science; (2) photometry; (3) infrared; (4) ultraviolet; (5) radio science; (6) magnetic fields; (7) plasma; (8) charged particles; (9) magnetosphere (hot plasma and radiation); (10) radion observations; and (11) plasma waves. An…

Provided for teachers and the general adult reader is an annotated and graded list of books and reference materials dealing with aerospace subjects. Only non-fiction books and pamphlets that need to be purchased from commercial or government sources are included. Free industrial materials and educational aids are not included because they tend to…

Statistics on both the production of astronomers and the employment opportunities now available and reasonably expected for the near future are examined. Barring the sudden and unexpected restoration of basic science to public favor, there seems to be no way of restoring equilibrium between the demand and the supply in astronomical employment…
