...study this portion, the scientists will employ three devices. The first, a spectrograph, was designed by James G. Baker, associate of the Harvard College Observatory. This instrument. weighing a ton, uses 16-inch mirrors and a four-by-six-inch grating with 15,000 individually ruled lines in each inch. According to Menzel, spectroscopic photographs of the outer corona have never been made with such sophisticated equipment...
Paschoff said that the Harvard team will be mainly concerned with observations of the solar corona-the vast outer atmosphere of the sun-with a spectrograph which he is building with Donald H. Menzel, professor of Astrophysies...
Better Focus. To obtain their proof, Stephen Little of the University of Texas and Astronomer Ronald Schorn of the Jet Propulsion Laboratory turned to the same kind of tools that they and other scientists had previously used in attempts to detect Martian water: the telescope and the spectrograph, which breaks light into its rainbow (spectrum) of colors and records it on a photographic plate. With the aid of a $100,000 NASA grant, mirrors had just been refinished on the 82-in. McDonald telescope, bettering its focusing by a factor of three. The optics of the spectrograph had also been...
Astronomers do not yet know why the Crab pulsar flashes, but some suspect that its bursts of light are generated by charged particles in its intense magnetic field. Now that they have seen the light, scientists are attempting to take a clear spectrograph of the pulsar and to determine if the light itself is polarized. They are investigating a new report by astronomers at an observatory on Malta, who saw strange "ghost" flashes about 3° to either side of both the Crab pulsar and another nearby pulsar. With these new clues, scientists hope to be able to learn more...
...Nasser's, and the same elements from the CBS recording. These "phonemes," as they are called, included such sounds as ah, ee, eye, o and yeh, which are common to both English and Arabic. Words from the tapes containing the phonemes were then fed into a spectrograph, which electronically translated them into signals that activated a stylus...
