Meeting at Harvard Observatory, a small group of leading U.S. astronomers agreed last week that a Swedish physicist, Bengt Edlen, had just thrown a good deal of light on the sun. It concerned the nature of the sun's corona-its turbulent halo of incandescent gases...
...half-million miles into space, sink back and leap again. Sometimes, strangely, clouds of gases appear out of nowhere far above the sun and blazing streamers lick back toward the sun's surface like prankish backward-movies of a high diver. What elements, astronomers have puzzled, form the corona? Where do the backward-flowing flames come from...
...corona is bright, but the sun itself outdazzles it except when blacked out by the moon (or by synthetic eclipses created by the device called a coronagraph). Since each of the 92 standard elements, when hot, glows with distinctive spectrum colors, astronomers can analyze the corona's chemical content with spectroscopes during eclipses. They have found in it about two dozen unidentifiable spectrum bands...
...Corona-haired Scientist Albert Einstein looks more like a concert violinist than most concert violinists do. To many a ruthless young mathematician, fiddling is the best thing Oldster Einstein does nowadays. In any event, he fiddles well enough to be heard in public. One sleety afternoon last week he made one of his rare semi-public concert appearances, in his adopted town, Princeton, N. J. Two things prompted gentle Dr. Einstein to brave reporters and photographers: he thought most of his audience would be children, whom he likes; the occasion was a benefit for the American Friends Service Committee...
Professor Menzel will give a free public lecture tonight about this instrument and the work done with it this summer. The title of his talk, which is one of a series of regular "Open Night" lectures at the Observatory, will be "Mystery of the Solar Corona...
