...College Observatory, found Russian astronomers equal to their U.S. colleagues in imagination and ability. Pulkovo Observatory at Leningrad, which has a scientific staff of 400, is particularly fine. The Russians have some excellent men in astrophysics-such as L. S. Shklovsky, who proved that the glow of the Crab Nebula is caused by high-speed electrons passing through the nebula's magnetic field-but top performers are not numerous...
Second prize was given to Robert A. Hatfield '59 for his essay, "A History of the Crab Nebula...

Watching with a radio telescope, the astronomers noted when the waves from the nebula were cut off by the moon. They reappeared on the other side in about one hour. Calculations showed that the nebula's radio waves had been bent very slightly: about...
...first example of the character of the unity of science, Oppenheimer told of some observations by Chinese astronomers 900 years ago that the "life-time" of a particular nebula they discovered was about 52 days. This also turned out to be the "lifetime" of one of the products of a nuclear explosion, Californium...

She had a clear little eye in her center (the signature of a hurricane), and around it were elaborate swirls like a spiral nebula (see cuts'}.
