Show Cause of Wrinkled Face Of Moon Nearer Discovery CHARLOTTESVILLE V a a Nov 1 19 A JP-A JT A great m mystery tery of astronomy what hat caused the craters craters craters cra cra- on the the moon appeared a astep astep astep step nearer solution today in a report to the National Academy of Sciences The craters crater numbering more than in an area about the size of the United States have been attributed to to meteors smashing into the moons moon's face and to some sort of cataclysm cataclysm cataclysm cata cata- not yet et guessed The report today shows an nn unexpected unexpected unexpected un un- un- un expected uniformity indicating the tho likelihood that they were caused by one ono type of cataclysm This finding came from the simple procedure of or counting the craters according to their sizes I This grouping was done by Dr F. F E E. E Wright of the geophysical laboratory Carnegie Institution of Washington In one family are arc craters crater four lour to eight miles miles' in diameter the tho next largest nine to 13 miles and so on A mile half diameter Is tho the smallest that can bo be seen with telescopes When these sizes were plotted a smooth curve resulted the clu clue to some understood still-not-understood uniformity in they the tiling thing which made the tho craters |
