...radically new explanation is now offered by one of the nation's top astronomers, Dr. Gerard P. Kuiper of the University of Chicago. After almost a year's moon-gazing through the McDonald Observatory's 82-in. telescope (the world's third-largest), near El Paso, Texas, he decided that the lunar markings were caused by a swarm of satellite planets...
According to Astronomer Kuiper, the moon formed close to the earth some 5 billion years ago in a common atmospheric envelope, much like a double-yolked egg. Both bodies were surrounded by a swarm of small satellites. As the earth solidified and the oceans formed, tidal friction sent the moon moving out into space...
...even after the "Einstein correction" has been allowed for, Mercury does not keep appointments accurately. This year Mercury crossed the sun about 20 seconds too soon, and the experts are now trying to figure out why. Astronomer Gerard P. Kuiper of the University of Chicago believes that the chief reason is the inaccuracy of man's fundamental timepiece, the revolution of the earth on its axis. For many reasons, including the drag of the tides and the little-understood motions of fluids in its interior, the turns of the earth vary slightly. This makes the earth a capricious clock...
Such planets cannot be rare, said Urey last week in a lecture at the New York Academy of Medicine. According to a star census taken by Astronomer Gerald P. Kuiper of the University of Chicago, there are 100 billion stars in the Milky Way galaxy, and one star in each thousand is believed to have planets circling around it. So there must be 100 million "solar systems" in the earth's galaxy alone...
...Gerard P. Kuiper's closeup of Pluto with the 200-in. Hale telescope on Palomar Mountain, which revealed the planet to be 3,550 miles in diameter (a previous estimate: about twice this size) and the second smallest planet in the solar system (TIME, June...
