...newly identified object, designated ScoX-1 by astronomers, is in the Milky Way Galaxy; it is between 300 and 3,000 light-years from the earth, and could be about 100 million miles in diameter. Though it has some of the spectral characteristics of a nova, a star that suddenly flares up, the X-ray-emitting envelope of gas surrounding it is apparently not expanding. This leads Giacconi to speculate that ScoX-1 may be a cloud of gas condensing into an infant star, or an existing stellar system surrounded by a gas cloud. "Or," he says...
...their film. Their painstaking labor produced tiny spectrograms that contained no color, only shadings of black and white, and were one-third of an inch long and a thousandth of an inch thick. Under the microscope, however, Sandage and Greenstein were barely able to discern strange patterns and spectral lines that had never before been observed in stellar spectra. Genuinely puzzled, Greenstein began to work out an elaborate hypothesis suggesting that the quasars were extremely dense and hot nearby objects, probably the remnants of supernovas containing highly excited or unfamiliar elements...
Soon after, he obtained a good spectrum from the quasar and, like his colleagues Sandage and Greenstein, he was puzzled by the sight of unfamilar spectral lines. But after staring at the spectrum for six weeks, Schmidt had a wild, almost desperate thought. Three closely spaced spectral lines on his photographic plate resembled hydrogen lines. But they were not in the blue segment of the spectrum where they belonged: they were superimposed on the red portion instead. Could they actually be hydrogen lines that had shifted to longer wave lengths...
...just as the wave length of sound from a train's whistle lengthens (thereby dropping in pitch) as it speeds away from a listener at the railroad station. Such an effect on light is known to astronomers as a "red shift" because it moves the characteristic lines of spectral light toward the red, longer wave length end of the spectrum...
Telemark is a palm-dampener when exiled Norseman Kirk Douglas and Richard Harris first parachute into the white northern wastes and go whooshing silently across the slopes, pursued by a gunner in a light plane or spectral Nazi ski troops. Director Anthony Mann (El Cid) makes the rest of the action, and the acting, seem quick-frozen. Too often chased indoors, Douglas confronts his ex-Wife Ulla Jacobsson, who appears eager to forgive his intervening philandering, and her kindly Uncle Michael Redgrave, who lends a touch of headmasterish solemnity, as if to prove that the Allied cause is just...
