...nothing less than a reappraisal of the origin and nature of the universe, largely because of the work of the man who appears on this week's cover. Dutch-born Professor Maarten Schmidt of California Institute of Technology is the astronomer who found the key to quasars (quasi-stellar radio sources), those bright, distant and mysterious objects that have been baffling astronomers. Now Schmidt and other scientists are using quasars to unlock some of nature's most difficult enigmas. Perhaps not since Galileo has an astronomer so jolted the specialists whose field of study is the universe...
...Feibelman call attention to the stellar eclipse so long before the fact? "Because of the possibility," he says, "that I-or the university's observatory-may not be around...
...looking backward in time, because the light that they see from very distant objects started its journey millions of years ago. They see the light from stars that no longer exist, and chart strange, starlike objects that could hold the secret of how the universe began. Quasars (for quasi-stellar radio sources) are the most intriguing of these objects, the oldest and most brilliant things in the observable universe, and the sources of powerful and mysterious radio waves. Now astronomers have identified a new class of quasi-stellar objects shining out of the past...
These are quasi-stellar blue galaxies -sort of quasi-quasars. Caltech's Dr. Allan Sandage described them in the Astrophysical Journal last week, adding that he suspected them of being "very distant, superbright galaxies reaching more than halfway to the horizon of the universe." Like quasars, they resemble stars, are up to 100 times as bright as an ordinary galaxy, and are receding from earth at tremendous speeds. Unlike quasars, they emit no radio energy...
...object recedes from the earth, the farther away it is. Using spectroscopic techniques perfected by Dr. Maarten Schmidt, a Caltech colleague, Sandage and Schmidt analyzed three of these objects, and found that they were moving away from the earth at tremendous speeds. One of them, BSO-1 (blue stellar object) seems to be speeding at the rate of 125,000 miles a second, making it second only to quasar 3C-9 (149,000 miles a second) as the most distant known object. The spectral patterns also showed a presence of ionized carbon atoms that have been detected previously only...
