...moon's flat maria (waterless "seas") are almost certainly covered with lava that poured out on the surface billions of years ago, said Astronomer Gerard Kuiper of Yerkes Observatory. In those days, Kuiper told the astronauts at Denver, the moon's interior was kept liquid by radioactivity, so any disturbance, such as a large meteor impact, was likely to cause an upwelling of lava. Kuiper thinks that smooth places on the maria will make firm landing spots for earth's spaceships...
...eyepiece of the telescope that towered through the observatory roof and spied on the moon. His voice echoed in the empty chamber. "Now, I note about twelve impact craters, and the largest of these I shall mark on the map with an A." said Dutch-born Dr. Gerard Kuiper head of the University of Chicago's Yerkes Observatory. By such sharply focused glimpses of scientists at work, Conquest (CBS) started to live up to its promise as a $1,000,000 series of ten science programs that will stretch into next season. After a talky start, the hour-long...
However, a theory recently proposed by Gerard P. Kuiper of the Yerkes Observatory of the University of Chicago, and strongly supported at last week's meeting by Eugene R. Rabe of the Cincinnati Observatory, indicates that Pluto may be actually only a runaway satellite of the neighboring planet Neptune...
...Cecilia H. Payne-Gaposhkin, chairman of the Astronomy Department, commented yesterday that direction and the shapes of the orbits of Neptune's satellites indicate that they have had an "exciting adventure." She termed Kuiper's theory "plausible, but not certain by any means...
Astronomer Gerard P. Kuiper at the University of Chicago, working at the McDonald Observatory, Texas, reported another color change on Mars. Its dark areas, which are generally supposed to be some sort of vegetation, are unusually drab this year. They are neutral grey, instead of the dull green that he had expected...
