...behaves like a very large star, equal in mass to 100 million suns. For a while it burns hydrogen and changes it to helium just as normal stars do, and the temperature in its center rises to 70 million degrees. Then the star burns its helium, forming heavier elements. Its central temperature rises to 500 million degrees, while its powerful gravitation causes it to shrink toward its superheated middle. In spite of its enormous mass, the great star is now only about one-third the size of the earth's orbit...
Chance for Survival. Hoyle and Fowler believe that these gigantic explosions are normal events in the life of galaxies. They happen over and over, and their violent nuclear reactions create the heavier elements that are found in stars and planets. For all their fierceness, though, they do not destroy galaxies or apparently damage them much. Some galaxies still seem in normal shape although the radio clouds from two explosions are speeding away from them...
Every year the migration is heavier, and for obvious reasons: Florida is more crowded than it used to be; the farther south the more certain the weather; and the jet plane has brought the islands within easy reach. The winter vacation, once a plutocrat's privilege, has become a fringe benefit for Everyman, who is discovering that there is nothing quite so soul-satisfying as toasting in the sunshine while one's friends and relations are shivering in the sleet...
...fore they were used to the new feeding system and their ham muscles were strong enough to support them. Professor Heitman watched their hungry struggles fondly, noting how their rear ends wiggled as they reached for their food. "I felt," he says, "that I was looking at very much heavier hams...
...Command last week took control of a new squadron of twelve Atlas missiles at Plattsburgh Air Force Base in upstate New York-bringing to 200 the total of U.S. combat-ready intercontinental ballistic missiles. The nuclear-tipped arsenal includes 126 liquid-fueled Atlases; 54 Titans, a bigger and heavier liquid-fueled missile; and 20 quick-firing, solid-fueled Minutemen. Each has a range of 6,000 miles or more, and each is zeroed in on an assigned target in the Soviet Union. The present total is at least twice the estimated strength of the Russian missile force. The longer-term...
