Such planets, if they exist, are too small and dark to be detected directly. For six years the Canadians have monitored 16 stars from an observatory on Mauna Kea, Hawaii, looking for the distinctive wobbling motion caused by the gravitational pull of nearby orbiting bodies. Epsilon Eridani, among several others, shows the telltale wobbles...

...instrument that uses a laser beam and colored dyes to analyze rapidly the structure of DNA molecules. And even while major astronomical discoveries are still being made with Caltech's 200-in. Hale Telescope, the school has joined with the University of California in building on Hawaii's Mauna Kea a 394-in. optical scope, the world's biggest, which will enable astronomers to see 12 billion light-years into space...

...comet's route at which it will pass directly in front of a relatively bright star. During one of these passages, which are expected to last about 15 minutes, they hope to learn how dust is distributed in the coma by analyzing the starlight shining through it. At Mauna Kea Observatory in Hawaii, nearly 14,000 ft. above sea level, Astronomer Dale Cruikshank is using infrared photometry and imagery to measure the heat radiation from Halley's coma and the distribution of dust within it, as well as to look for certain isotopes of carbon and hydrogen. Says...

...towering Mauna Kea, a 13,800-ft. extinct volcano in Hawaii, is a peculiar mix of the exotic. Gnarled koa trees twist up from its tropical slopes, where the endangered palila bird, a tiny yellow honey creeper, crushes rock-hard mamane seeds with its beak. But up on top, science has taken over. Because the exceptionally dry and stable atmosphere over Mauna Kea makes the site among the world's best spots for star gazing, six telescopes have been built on the volcano's crest, and two more are under construction...

...mirrors placed on a common mount. Each mirror would be 2 ft. thick but largely hollow, shaped like a honeycomb. The four could either be used in tandem, creating the equivalent of a gigantic 590-in. mirror, or separately. Overseas, Japanese astronomers also have their eyes on Mauna Kea; they hope to build a 295-in. telescope on the volcano by the 1990s. The European Southern Observatory, headquartered in Munich, is considering an array of four 315-in. telescopes that could, like the N.O.A.O. instrument, act in concert...
