Radio age (Jan 1927-Jan 1928)

RADIO AGE for January, 1927 New Comet Will Not Hit Our Earth THREE comets are now visitingthe neighborhood of the earth. Two are old friends, having been with us before on their periodic returns to the central part of the solar system. The third is apparently new, no comet of similar orbit having been detected before and none having been expected exactly in the position of this one. It was discovered on Nov. 6 by Professor Comas Sola of the Astronomical Observatory of Barcelona, Spain, which discovery has since been verified by a score or more of observatories both in Europe and America. According to preliminary computations of the comet's orbit made by the Copenhagen Observatory, it will be with us for several months, reaching its nearest point to the sun on May 14, 1927. As yet the comet is very faint, being visible only in large telescopes. Comets are believed to be clouds of solid particles with some gas surrounding them. There is no probability the new comet will come especially close to the earth, but even if it hit us it probably would do no harm. Our air would protect us from the flying particles of the comet, causing them to burn up just as do the meteors or "shooting stars," thousands of which hit the earth's atmosphere each day.
