Carbon 13 was observed in the comet Ikeya in about the same proportion as it occurred on the earth by Dr. Jesse L. Greenstein of the Mount Wilson and Palomar Observatories and Dr. Antoni Stawi-kowski of the Nicolaus Copernicus University of Poland working at Palomar Observatory. "This lends credence," said Dr. Greenstein, "to the theory that comets, and there may be millions of them, were formed in about the same region of the solar system as the earth and were blown into their present, vast, elliptical orbits. The fact that the carbon isotope ratio is similar for Ikeya and the earth argues against the theory that comets are captured, interstellar wanderers that were formed beyond the solar system. If comets were born elsewhere, one would expect them to be unlike earth." (NYT, 11/30/64, 11; AFOSR Release 11-64-3 "S")
It was announced that a new ultraviolet radiation spectrograph had been developed at NASA Goddard Space Flight Center in an effort to solve the mystery of "airglow." The spectrograph would be carried aloft by a rocket and Would be expected to reveal the constituents and mechanisms of the airglow. (NANA, San Diego Union, 11/29/64)
