...select their computers on the basis of increasingly esoteric technical specifications. IBM alone sells seven basic variations on its bestselling model, ranging from the low-cost PCjr to the top-of-the-line IBM PC AT. To distinguish between these machines, consumers have to measure memory in kilobytes and disc storage in megabytes. To understand the pros and cons of IBM-compatible computers built by AT&T, Compaq or Hewlett-Packard, they must learn to identify silicon chips by name and measure their speeds in millions of cycles per second...
...capacity. At the same time, Apple dropped the price on the smaller Macintosh by $300, to $2,195. Reason: rumors about the introduction of a bigger machine were cutting into Macintosh sales. The company is now plagued by reports of yet another improved Macintosh that will have a hard-disc memory storage unit built...

...Milky Way. In a new, highly detailed photograph of Beta Pictoris, a neighborly 293 trillion miles from the sun, Bradford Smith of the University of Arizona in Tucson and Richard Terrile of the Jet Propulsion Laboratory in Pasadena, Calif., have discovered that the star is encircled by a dim disc of gas and solid particles. The astronomers believe that those particles may be the signs of newborn planets and worlds in formation. The spectacular image is the first visual evidence of another solar system, raising the possibility that extraterrestrial life may some day be found. "The time will have...
...called a coronagraph, which can block out the most blinding light of a star, making a kind of eclipse. With Beta in shadow, Terrile and Smith then attached a special detector to the telescope that picked up the weakest light signals around Beta. The resulting image of an encircling disc looked remarkably similar to our own solar system. Analyzing the configuration of the disc with a computer, they found that some matter may have condensed to form planets...
