...million cogeneration plant, designed to supply energy to 13 Medical Area institutions--including Harvard's three medical schools and its affiliated hospitals--has been the subject of intense community controversy because of the allegedly dangerous levels of nitrous oxides it would emit...
Here's sampler of the advances made largely by means of the invisible ultraviolet and x-ray radiation they emit. Researchers have especially concentrated on the active, flaring regions of bright stars, for it now seems that their atmospheres are energized far more powerfully than our Sun. A number of unanticipated discoveries concerning rotation, magnetism, size and dynamics suggest that a completely new outlook on the physics of stars may be required to fully understand them...
Dense, dark and dusty hodgepodges of galactic gas and dust where, quite literally, there is nothing to see were examined by means of the invisible radiation they emit. Radio and infrared techniques now enable us to "listen" to huge interstellar clouds slowly contracting to form stars. Thus, we are now learning a great deal about the embryonic stages of stars, a subject about which the oldest science--astronomy--had been experimentally ignorant until the dawn of the 1970s...
...almost unimaginably powerful. Such a regions not really an object, as much as a hole--a spatial domain from which neither visible nor invisible radiation can escape. It seems that the guts of black holes are unexplorable. But matter falling into such weird regions can, and apparently does, emit radiation just before being swallowed, perhaps forever...
...safest method of permanently burying nuclear garbage, some of which remains radioactive for thousands of years. At present, the most highly radioactive wastes, such as spent fuel rods, are stored under water in plant "swimming pools," but reactor operators are running out of pool space. Wastes that emit less radioactivity are placed in sealed containers and trucked to dump sites for burial. However, some of the containers have leaked, either underground or in transit, and dump sites have been closed in Hanford, Wash., and Beatty, Nev. This leaves only one dump in the entire country that still accepts nonmilitary atomic...
