...earth matters, but a recent issue contains an appeal that reaches rather far out. In a letter to the magazine, Astronomers John C. Brandt, Stephen P. Maran and Theodore Stecher ask archaeologists for help in determining the age of a giant celestial gas cloud. Known as the Gum Nebula, the cloud has been attracting more than usual attention among astronomers. At its center, some 1,500 light-years away from earth, they have discovered a pulsar -a neutron star that emits regularly spaced radio signals. What possible information could archaeologists offer? Quite a bit, the astronomers explain. Both...
...multibillion-hertz range into more easily detectable radio frequencies of about 100 million hertz. After adapting this device to the National Radio Astronomy Observatory's 36-ft. dish antenna at Arizona's Kitt Peak, the Bell scientists aimed the radio telescope at the distant Orion Nebula, a region of glowing gases more than 1,600 light-years away, a favorite target of molecule hunters...
...college English, and is now, at 42, lecturer in English at Ohio University. In its original shorter form. Flowers for Algernon won the Hugo Award as the best science novelette; it became an effective television play; in its expanded form it won the best novel-of-the-year Nebula Award; and it is the basis for the recent movie Charly (which, for ali its strong points does not come close to matching the book...
...Donald Taylor defied the beliefs of more experienced astronomers who were certain that the strange objects would be too small and distant to be seen through terrestrial telescopes. Undaunted, they pointed the 36-in. telescope at Arizona's Steward Observatory toward a small star in the Crab nebula, the glowing, cloudlike remnant of a supernova (stellar explosion) that was first witnessed from earth...
...Arizona astronomers had three good reasons for picking their target: 1) most scientists now believe that pulsars are neutron stars, small and incredibly dense spheres that are residues of exploded stars like the one that formed the Crab nebula; 2) a pulsar had recently been detected in the Crab by radio telescopes and 3) the Crab pulsar, or neutron star, beeps faster than any discovered to date. Thus it is presumably younger, hotter and brighter, and could be seen more easily than any other...
