...side of the moon will keep moon experts theorizing for many years. The seas are really flat, low plains filled with dust or lava. They must have been formed rather late in the moon's history, because few meteor craters pit their surfaces. Astronomer Gerard Kuiper of the University of Chicago thinks that the seas were made by the impact of asteroids up to 90 miles in diameter, which blasted great holes in the crust at a time when the moon's interior was hot and plastic. Dark lava welled up in the holes, and is visible there...
Although the earth's magnetic field is still something of a mystery, most geophysicists think it is caused by motion of the liquid metal core of the earth's interior. The University of Chicago's Astronomer Gerard Kuiper reasons that if the moon has no magnetic field, it cannot have a liquid core. The Russian observation, he says, backs up his belief that the moon was formed at the same time as the earth, but since it is much smaller, its metal core has cooled off and solidified. Other moon experts are not so sure. Nobel Prizewinner...
...Lunik II undoubtedly blasted a crater, which Kuiper estimates as about 100 ft. in diameter with walls 10 ft. high. If such a crater happened to be in a smooth place, it should be detectable by a powerful telescope, under ideal conditions, as a faint bright spot. If the Lunik crater were inside a big crater or in a jumble of craters, it would probably not be visible...
...know precisely where the Lunik landed. Astronomers from the Ukraine's Kharkov Observatory, who watched and photographed the moon at the moment of impact from a high-flying airplane, think they saw 'a light effect" at the right instant. U.S. astronomers doubt it. Moon Expert Gerard Kuiper of the University of Chicago thinks that no flash of impact would have been visible against the moon's sunlit surface. He questions a Hungarian report of seeing a long-lasting dust cloud on the moon. Since the moon has virtually no atmosphere, dust particles tossed up from the surface...
...Urey still thinks that the clouds in the Venusian atmosphere may be made of water droplets like clouds on earth, but few astronomers agree with him. Dr. Kuiper thinks they are made of fine dust particles of carbon suboxide (0302). In an attempt to prove this theory, he made a mixture of carbon dioxide and carbon monoxide and exposed it to assorted radiation at the Argonne National Laboratory. Sure enough, carbon suboxide formed, and its molecules stuck together to make particles of yellowish polymer...
