These "Lilliputian stars" do not glow like regular stars; the pressure and temperature inside them are not high enough to support the thermonuclear reactions that keep stars hot. But they need not be cold. "The heat to support life," said Shapley, "would come from their interiors, and they would not be dependent on a sun as we are. In such bodies, radioactive thorium or potassium might provide a source of energy...
Once in orbit, the little jets went back into action. To keep the satellite horizontal, they had to make it turn just as fast as it circled the earth: one revolution, one turn. This was done by an infrared scanner, which watched the line of the horizon ahead and released little spurts of gas to keep the satellite's attitude stable. This complicated operation seems to have worked well. As Discoverer II circled the earth, its directional radio signals kept at a steady level. If Discoverer had not been stabilized properly, they would have fluctuated as the satellite wobbled...
When astronomers (or science-fiction writers) speculate about nonearthly kinds of life, they generally think of strange beings existing on planets revolving around a star that is at the proper distance to keep them reasonably warm. Astronomer Harlow Shapley, former head of the Harvard Observatory, has figured that there are probably 100,000 life-bearing planets in the Milky Way galaxy. Last week Shapley suggested that the universe may contain another class of celestial bodies that could sustain life. They are neither planets nor true stars, and are somewhere in between the two in size-perhaps 100 times bigger than...
From the combination of Searles-Rose data, there emerges a family conspiracy not only to drive a man crazy, but also to keep him that...
...York transit deal would be a big gamble for Roy Chalk. His offer has been received cautiously by most of the city brass except Transit Boss Charles Patterson, who favors it. Last week Chalk relaxed his terms by pledging to keep the 15? subway fare so long as the city guarantees him an after-tax profit of 6½%. As usual, he was mum about who was putting up the bulk of his bankroll. Grinned O. Roy Chalk: "I'm a poor man -never have more than 50 bucks with me. The big thing is, I know where...
