...delegates represented some half-million supporters in all parts of South Africa, roused to resistance against the increasingly severe racial segregation policies of 77-year-old Prime Minister Daniel Malan,*a distant cousin of handsome, pipe-smoking Sailor Malan...
Hubble found that all distant nebulae are moving away from the earth at spectacular speeds, and that the more distant they are, the faster they move. Using more delicate techniques, his colleague Humason continued his work. With the 100-inch Mt. Wilson telescope, Humason photographed nebulae whose red-shifts indicate that they are receding at 25,000 m.p.s...
Blue to Green. The 200-inch Palomar telescope was built primarily for studying more distant nebulae. It can photograph them as faint blurs at distances something like one billion lightyears, but getting their spectra is more difficult. The light from the nebula is concentrated by the telescope's great mirror upon a prism, which spreads it into a spectrum one-tenth of an inch long. So dim is the image on the photographic plate that four to six hours of exposure are needed to make the picture...
...most distant nebulae studied so far, the bright "H" and "K" lines of glowing calcium, which are normally blue, are shifted into the green band of the spectrum. If they were bright enough to be seen in color, human eyes would actually see them as green instead of blue. This means that the motion of the nebula has lengthened the wave length of its blue light by more than 800 angstroms (.000003 in.). "It's a tremendous shift," says Dr. Hubble. "In our own stellar system, the average shift is only a fraction of one angstrom...
Another theory was developed by Britain's late Mathematician Edward A. Milne, who died last year. The light from the distant nebulae, said Milne, is "fossil light." It started its journey several hundred million years ago, and light in those ancient days may have been different from light today, just as dinosaurs are different from modern animals. The glowing calcium atoms that now give blue light, for instance, may have given green light then. When the fossil green light reaches the earth, Milne said, it fools astronomers into thinking that the nebulae it came from are moving away from...
