...Like rats out of a sewer," said one witness of the aftermath. Another described a lingering "could of brilliant yellow smoke." So ended the fun at Freedom Square last midnight when an army surplus smoke bomb thrown into the window of the Harvard Lampoon from Bow St. brought the festivities of election night...
...planets, stars, and galaxies came to us on light waves in the narrow, visible portion of the spectrum. Astronomers have likened the visible region of the electromagnetic spectrum--which stretches from short-wave gamma rays at one end and the long radio waves at the other--to a tiny window looking out on the universe. Most of the revolution in modern astronomy stems from the design of instruments that have opened up new "windows" in the electromagnetic spectrum...
...dozen or so stations in the United States and abroad where University astronomers are working; others are designed to observe the universe from satellites above the earth's obscuring atmosphere. The following is a report on three of these new electronic instruments, each of which peers through a different window in the electromagnetic spectrum: the infrared, the far ultraviolet, and the radio...
...Another "window to the universe, until recently closed to astronomers on earth, lies at the ultraviolet end of the electromagnetic spectrum. The earth's atmosphere absorbs most of the ultraviolet light reaching it from the sun and other stars. A Harvard ultraviolet spectrometer, designed to look closely at the sun from a satellite outside the earth's atmosphere, has already been tested aboard a rocket and following further test, will join a number of other instruments aboard an orbiting solar observatory sometime this year...
...ultraviolet spectrometer, about the size and shape of a window box, will provide new information about the solar flares that erupt now and then from the sun's atmosphere, appearing as tongues of luminous gas flicking outward around sun spots. During a flare, clouds of ionized hydrogen gas--protons and electrons--shoot out, filling interplanetary space with intense radiation. When these clouds encounter the earth and pass through the earth's magnetic field into the polar regions, they produce the northern lights, and cause short-wave radio transmission to fade or black...
