The controversial objects, which appear to some to violate the known laws of physics, may prove to be highly condensed, rotating centers of extremely distant galaxies. (Author/DF)

Radioastronomy reveals that clouds between the stars, once believed to consist of simple atoms, contain molecules as complex as seven atoms and may be the most massive objects in our Galaxy. (Author/DF)

The National Register of Scientific and Technical Personnel is summarized with regard to physicists and astronomers. Included are salary distributions for physical scientists, median salaries of physicists by employer, educational and work experience. Unemployment figures are presented. Separate data for women are included. (TS)

Discusses new problems arising from the growing observational data through radio telescope arrays, involving the origin of radio sources, apparent superluminal velocities, conversion of radio sources to relativistic particles, and the nature of compact opaque and extended transparent sources. New physics may be needed to answer these cosmological…

Although many experiments to detect gravity waves are underway, and others are planned, so far none of them has reproduced Joseph Weber's results, first reported in 1967. (Author/DF)

Describes the basic design and principle of operating an optical-infrared telescope, the MMT. This third largest telescope in the world represents a new stage in telescope design; it uses a cluster of six reflecting telescopes, and relies on an automatic sensing and control system. (GA)

Highlights the career and accomplishments of Philip Morrison, one of the most thoughtful advocates of arms control, valued for his scientific contributions to the Manhattan Project, theoretical physics, astrophysics, and the public understanding of science. (Author/JN)

discusses the cosmology theory of a black hole, a region where an object loses its identity, but mass, charge, and momentum are conserved. Include are three possible formation processes, theorized properties, and three way they might eventually be detected. (DS)

Many properties of new particle field theories can only be tested by comparing their predictions about the physical conditions immediately after the big bang with what can be reconstructed about this event from astronomical data. Facts/questions about big bang, unified field theories, and universe epochs/mass are among the topics discussed. (JN)

Gives a short biography of James E. Keeler, and describes some of his outstanding discoveries, and his pioneering work in observational research where he applied physical methods to the analysis of planets, stars and nebulae. (GA)

Presents the initial analytical results of 1973 survey data obtained from over 52,500 respondents in the physics and astronomy community. Indicates a decrease in unemployment and a continuous salary increase from 1970 to 1973. Included are descriptions of subfield employment, work activities, and situations of minority groups. (CC)

Discusses major developments in radioastronomy since 1945. Topics include proposed facilities, very-long-baseline interferometric array, millimeter-wave telescope, submillimeter-wave telescope, and funding for radioastronomy facilities and projects. (JN)
