...most brilliant objects in the universe, shining with the light of from 50 to 100 galaxies, each containing 100 billion stars as bright as the sun. Where did all the energy come from? Searching for answers, Dr. Schmidt and his colleagues pored over spectrograms which showed quasar light separated into its various wave lengths. They knew that the most distant fast-moving bodies should show spectrogram lines of far ultraviolet light whose waves had been lengthened so much in their shift toward the red that they would appear in that part of the spectrum where the much longer waves...
This independent observation is not so firm a support as a photograph would be, and it is not so informative as a spectrogram, which might tell what chemical elements are responsible for the red color. But astronomers are notoriously skeptical about strange eruptions on the moon, and these confirmed reports are unusually convincing. They also tend to bear out 1961 sightings by Russian Astronomer Nikolai Kozyrev. Dr. Hall believes that the fierce heat of returning sunlight may have released gases from the lunar interior. At a Dallas conference on newly discovered astronomical objects last week, Nobel Chemist Dr. Harold Urey...
...Durovic surrendered a sampling of Krebiozen to FDA agents last July, and at once chemists began systematic analysis with an infrared spectroscope. After the complex spectrogram was compared with that of thousands of other organic compounds, the pattern of Krebiozen was found to match that of creatine. Ironically, Krebiozen is much easier to produce than Dr. Durovic may realize; he uses benzene, in which creatine is highly insoluble, for extraction. Using plain water as a solvent for the process, he might get several hundred times more amino acid derivative from each horse...
...Kozyrev shows a spectrogram with an unusual bright streak, and explains what he thinks happened. The reddish patch over the crater's central peak he believes was caused by volcanic ash shot out of the moon's crust. The dust settled quickly, since there is no air to keep...
...stream of gas followed the ash and spread into the vacuum above the moon's surface. The gas contained carbon molecules of various sorts, and ultraviolet light from the sun made them glow brilliantly, accounting for the bright streak on the spectrogram...
