...Cygnus, and optical astronomers could find nothing there. At last the Palomar telescope, guided by a new and extremely accurate radio fix, photographed an extraordinary scene that looked like a collision of two enormous galaxies 500 million light-years away. Galaxy collisions are possible, though unlikely, and they might emit radio waves because of churning gases between their hundreds of billions of stars...
Loud Stars. Most true stars in the Milky Way galaxy maintain fair radio silence, but a few of them transmit powerful radio waves that have the astronomers baffled. About half a dozen radio stars have been identified optically, and they prove to emit peculiar assortments of visible light. Astrophysicists are busily studying these spectra, hoping to find some connection between them and the stars' radio loudness...
Happily, this month's Tocsin News Forum shuns the strident, there's no time, brother tone which undergraduate writers on Berlin and disarmament so readily emit...
...polite truth or a romantic stage presence which melts in the wings into a conservative reality. If this is what the American people want there are American "folk singers" who chant Russian peasant songs to the accompaniment of periodic taps on the dashboard of a Mercedes sedan, or emit plantation work songs out over the violin section from the confines of tight black pants and silk shirts. These are the part-time romantics who make their deliveries without the "Alice-in-Wonderland logic" and with all the power and effectiveness of half the critical mass. The public, in its approach...
...physical bodies emit heat in the form of infra-red rays invisible to the human eye. Out of this simple scientific fact has grown an exciting and important new industry that is already big in missile and space work. Unlike more familiar uses of infra-red-which use it as a heat source to cook foods quickly-the new applications need supersensitive detection equipment to receive infra-red and "see" the source it comes from. Infra-red detection now adds a new dimension to sight...
