New look at the universe

Dr. Herbert Friedman, astrophysicist with the U.S. Naval Research Lab, uses a piano to demonstrate that the range of the spectrum from red to violet is one octave of electro-magnetic frequency and notes that the earth's atmosphere blocks all but thirteen of the total sixty octaves of radiation frequencies. He shows a photo of Karl Jansky and a picture and soundtrack of lightening-produced "whistlers," which Jansky studied. In a 1945 film clip, V-2 rockets carry a Lyman alpha solar disk camera above the earth's atmosphere to study ultra-violet wavelengths such as the Lyman alpha line, discovered by Theodore Lyman at Harvard in 1912. The eponymous camera is described in a film as are the photon counters used in the rocket to send data from the flight to the ground. Pictures reveal the sun's characteristics, such as sunspots, flares, and plages. A 1959 detailed photo of the sun taken with the Lyman alpha camera shows the Lyman alpha regions. Another film discusses the study of solar flares and the use of "push button" rocketry to measure them. A film shows two-stage rockets launched from the Pont Arguello, CA U.S. Naval Missile Facility to study the ultraviolet x-ray emissions of solar flares. A chart displays the sun's photosphere surrounded by outer and inner coronas and a chromosphere. An animated segment and film clips document the attempt to photograph the sun during the October 12, 1958 total eclipse. Dr. Friedman concludes the program by explaining the detection of ultra-violet nebulosity in the night sky and lists questions researchers are trying to answer about Lyman alpha light and hydrogen-filled galactic space.
