Radio Waves from Saturn Measured.--University of Michigan scientists have measured radio waves from the planet Saturn. The University's head of radio astronomy, Professor Fred T. Haddock, reported these first clear and unambiguous detections and measurements of Saturn and a planetary nebula to the 13th General Assembly of the International Scientific Radio Union.
The findings are basic contributions to scientific knowledge. They could also help save money in future planetary exploration and possibly lead to modification of theories of planetary nebulae.
The measurements were made with the U-M's high precision 85-ft. radio telescope through the use of a new and highly-sensitive ruby maser amplifier. This amplifier was developed by the University's Willow Run Laboratories in an application of its earlier discovery, in 1957, of maser action in ruby.
Saturn's atmospheric temperature was found to be 100 ยฐ K. (-283 ยฐ F.), about the temperature expected on the basis of optical studies. The naturally generated radio waves are emitted from various depths in the planet's atmosphere, Prof. Haddock pointed out.
The measurement may make possible study of the temperature and density of the rings of Saturn and of the distribution of gases in Saturn's atmosphere. Precise measurements at a number of frequencies are needed for this, Professor Haddock pointed out. The U-M findings are accurate within 10 per cent, which Haddock termed "pretty good."
