...part of the celebrations, 2,500 cities and towns have adopted civic projects that range from Ottawa's plan to plant 70,000 flowering crab apple trees to a Japanese garden in Lethbridge, Alta., that expects to get a school of royal carp from Emperor Hirohito's moat. Athletically, Canada will be host to no fewer than 17 international competitions, from snowshoeing (in Ottawa) to water skiing (in Sherbrooke, Que.) to the Pan American games in Winnipeg...
...sources outside the solar system. Their search was not rewarded until 1962, when more sensitive instruments picked up the first X-ray emissions from outside the solar system. But until this year, only one additional visible object had been definitely identified as an X-ray producer: the familiar Crab Nebula.* Though their relatively crude instruments sensed X rays from about two dozen other vaguely defined areas of the sky, astronomers have been un able to tell which, if any, of the known celestial bodies were producing them. Now X-ray astronomy seems to be coming of age. The strongest...
...after. In A.D. 1054, Chinese astrologers recorded a brilliant "guest star" supernova that suddenly exploded one night in the constellation Taurus. Located near the tip of the left horn, the star remained visible even during bright daylight. This same supernova's remains can be seen today as the Crab nebula, a diffuse, glowing gas cloud 3,500 light years away, which continues to expand at 800 miles per second...
...improved, the vague shapes in the sky contracted until it became possible for radio observers to direct optical astronomers to smaller and more manageable areas. In 1949, astronomers using these directions spotted the first visible object outside the solar system that was associated with a discrete radio source: the Crab Nebula, the remnant of a star explosion (or supernova) in the earth's Milky Way galaxy. Shortly afterward, they identified the first visible source outside the Milky Way: a large galaxy 50 million lightyears* from earth. In the next decade, as radio and optical astronomy continued their fruitful alliance...
Among its tourist attractions, Baltimore boasts of succulent crab cakes, miles and miles of red-brick row houses, and the fourth busiest harbor in the nation. It quickly glides over its most famous tourist lure, the seamy, sinful strip known as "the Block," a symbol and byproduct of a police department that ranks with the worst in any major U.S. city...
