Calling such indoor smog an emerging health problem, the Comptroller General has cited half a dozen harmful substances detected in unusual quantities in super-sealed buildings. Among them: carbon monoxide and nitrogen dioxide, both byproducts of smoking, gas stoves and leaky furnaces; the radioactive gas radon, which results from the natural decay of radium, an element found in soil, rocks and other building materials; and numerous particles of dust, soot and asbestos...
...thousand rings round Saturn, icy moons and lakes of liquid nitrogen...
...Saturnian rings and a few gaps between them were known. Now there seem to be 1,000 rings or so. One of the so-called gaps may contain several dozen ringlets. Titan, the largest moon in the solar system, appears to be wrapped in a dense atmosphere of nitrogen vapors, rather than methane-the best guess before Voyager-and its surface may be awash in a cold sea of liquid nitrogen. Saturn's entourage of other satellites, until now no more than bright gleams in earthly telescopes, also proliferated-by three -to at least 15. Chunks...
Voyager I's latest data transmissions also enabled the Pasadena scientists to determine that Titan, Saturn's largest moon, has a dense, extremely cold atmosphere, composed primarily of nitrogen. which might have allowed Titan to follow a development path similar to the earth...
Three separate experiments using Voyager I data indicate that Titan's atmosphere is almost 90 per cent nitrogen. Eshleman hypothesized that since the earth's atmosphere is 78 per cent nitrogen, the two bodies may have similar origins and development paths...
