Discusses the process of stellar death and the correlation between the size of a star in solar masses and its way of death. The amount of mass loss that occurs during the life and death of a star is also discussed. (HM)

Discusses the trials done by physicists to understand unfamiliar nuclear physics events taking place in the air. Also briefly describes the effects of detecting the primary cosmic ray. (Author/SK)

Briefly describes some experiments which give indications that neutrinos may not be massless particles. (SK)

Six articles concerned with energy use, energy research and sources of energy are included in this issue. Articles are titled (1) Energy Systems; (2) Energy-Related Research; (3) Solar Energy; (4) Geothermal Energy; (5) Coal; and (6) Utilization of Energy. (RH)

Synchrotron radiation is a unique form of radiation that spans the electro-magnetic spectrum from X-rays through the ultraviolet and visible into the infrared. Tunable monochromators enable scientists to select a narrow band of wavelengths at any point in the spectrum. (Author/BB)

Discusses the process of star formation. Infrared and radio astronomy, particularly microwave astronomy is used to provide information on different stages of stellar formation. The role of dust and gas which swirl through the interstellar regions of a galaxy and the collapse of a cloud in star formation are also presented. (HM)

Discusses how technological advancement, in particular: the explosion in useful wavelengths and the revolution in telescope design and fittings, multiplies astronomers' grasp of the cosmos. (HM)

A description of the moon's total eclipse indicating the path, traveling speed and duration, followed by a concise description of how a total eclipse happens and what scientists actually study with relations to an eclipse. (EB)
