...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...
State of Shock. Acting on his hunch, Schmidt assumed that the lines he saw were really hydrogen lines. He measured the shift and calculated that 3C 273 was moving away at 15% of the speed of light, or about 28,000 miles per second. This meant, according to Hubble's law, that the quasar must be about 1.5 billion light-years from the earth, instead of being a faint, nearby star - as most astronomers had assumed...
...strongest of hydrogen's lines, called H-alpha, seemed to be missing entirely from 3C 273's spectrum. If Schmidt's theory was right, the line was not missing but had shifted into the infar-red region of the spectrum, where it would not register on an ordinary photographic plate. Schmidt remembered Astronomer Beverley Oke had already studied the spectrum with an electronic gadget sensitive to invisible infrared. Oke had found a prominent line precisely where Schmidt thought that H-alpha should be, shifted into the infrared. 3C 273 was moving faster than seemed possible...
...bodies has generated some fantastic intellectual inventions, some of which may yet turn out to be accurate. Fred Hoyle and a California Institute of Technology colleague, William Fowler, have suggested that quasars might well be massive superstars whose nuclear fires have died down because of the depletion of their hydrogen fuel. Such stars, they say, would begin to collapse, contracting under their own gravity. And the tremendous energy released by matter falling toward the star centers might well be of a magnitude that could explain a quasar's fierce radiation...
...tail of flame, Saturn 1B burned for 2 min. 26 sec., at which point it was 35 miles up and moving at 5,400 m.p.h. Next came the tricky second stage, a single 225,000-lb.-thrust engine powered by an exotic combination of liquid oxygen (lox) and liquid hydrogen (LH2). While lox boils off at a difficult -290° F., LH2 boils at -423° F., thus requires extreme pressurization to keep cool. Moreover, in weightless space, LH2, like mercury, tends to gather into a ball or spin off into tiny globs; simply to feed the fuel from tank...
