...also sense a shift in public opinion, a growing feeling that the turmoil has gone on long enough. Increasingly, newspapers and television news programs report comments signed by "average citizen" or similar pseudonyms, calling for calm. In controlled media, such messages are obviously suspect. Even so, they appear to mirror genuine feelings. Says one West German expert assigned to follow the Polish crisis: "When you have to stand in line for hours for food, then walk kilometers to work because of transport strikes, it gradually grinds you down. As the euphoria wears off, you begin to realize that the system...
...favorable climates. Moonlight or the glare from cities and highways can also spoil the view. As the twinkling of the stars shows, the dust and gases in the earth's atmosphere scatter heavenly light, thus limiting the effectiveness of every telescope, even such monsters as the 200-in. mirror atop California's Palomar Mountain...
...instrument may be the most important telescope ever built. Lofted into earth orbit by the space shuttle, it will expand the astronomers' universe (increasing its observable volume 350-fold) and render whatever it reaches visible in exquisite new detail. The space telescope's primary lens-actually a mirror-will measure only 94 in. across, a middling size as large reflecting telescopes go. Yet it will provide images ten times sharper than the biggest instruments on the ground, including the new 236-in. Soviet telescope in the northern Caucasus. The NASA telescope will also be able to pick...
Most reflector telescopes, including the smallest backyard instruments, play a kind of Ping Pong with light entering the open end of the tube, and so does the space telescope. Light strikes the primary mirror, and then is focused and bounced back to a small secondary mirror (12 in. in diameter) directly in front of it. Rebounding off this mirror as well, the captured light will be funneled through a central hole in the principal reflector and onto a bank of scientific instruments: two cameras, two spectrometers (for analyzing light) and a photometer (for measuring its intensity). All the information from...
...with Murdoch's saucy Sun and sleazy News of the World, and the great worry is that the Times will itself adopt what the paper just four months ago described as "the breathless, grubby vision of the world inherent in the Murdoch style." Tongue tucked in cheek, Daily Mirror Columnist Keith Waterhouse told readers not to fret. "The girls," he wrote, "will appear in the Times Literary Supplement wearing fishnet stockings and mortarboard...
