Reviews practical applications, particularly in scientific research, of hot air balloons. Recent U.S. governmental projects in near-space research are described. Lists (1) major accomplishments of scientific ballooning, including discoveries in cosmic ray particles, gamma and x-rays, and other radiation; (2) measurement of fluorocarbon…

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 efforts which have been accomplished in extragalactic astronomy (the study of bodies and systems beyond the Milky Way) since 1929. Some of the most perplexing problems of extragalactic astronomy such as the missing mass of the galaxies are also discussed. (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)

Presents a description of the world's largest radio/radar antenna, the Areciba Observatory in Puerto Rico. Activities at the observatory are discussed as well as the scientific research in the field of radio astronomy. (SA)
