Last week The Telescope, published by Harvard Observatory, pointed out that conclusions as to the size of the particles in this red nebula could be drawn from its color. If the nebular material were microscopically fine, the light of Antares would be reddened, just as the sun is reddened when it shines through a long slope of the hazy atmosphere at evening. Also, the light from the nebula would be made bluer by selective scattering of the same kind which makes the earth's sky blue.* Actually, the color of the star and that of the nebula are almost...
...parading through the heavens in the raiment of a beggar" was related by him last week at a meeting of the American Institute of Electrical Engineers in Manhattan. Forty years ago a British amateur named Denning spotted a faint blur in the constellation Camelopardus. It was identified as a nebular nucleus, or blob of cosmic matter. This apparently pusillanimous thing was of the twelfth magnitude, far below naked-eye visibility. Astronomers did not bother to name it but set it down by number, I. C. 342, in the Second Index Catalog (1895). With better cameras and telescopes...
...Haven, Conn. last week Edwin Hubble delivered the first three of eight endowed lectures on the present state of nebular knowledge, free to Yale students and townsfolk. He wasted no time whizzing his hearers past the solar system, past the local star cluster, past the local star galaxy (the Milky Way) to the limits of the known universe. Dr. Hubble's longest looks into space have disclosed star-swarms 500,000,000 light-years away, and this appears to be the limit of Mt. Wilson's giant telescope. Thus the observable universe is a sphere about a billion...
...collected and examined toward the end of the 19th Century it was discovered that Swedenborg had been ahead of his time in almost every field of science. He invented an ear-trumpet and mercury air pump, sketched a submarine, airplane, machine gun, fire extinguisher, steam engine. He propounded the nebular hypothesis before Kant and LaPlace, anticipated all Scandinavian geologists in his studies of paleontology, was first to explain the phenomenon of phosphorescence, beat modern physicists by 150 years with his molecular magnetic theory and modern physiologists with his discoveries concerning the nature and activity of the brain, spinal cord...
...deduced in this manner, since the spectra are too faint to be analyzed. But it has been observed that speeds are closely proportional to distance, increasing about 1,000 miles per second for every 10,000,000 light-years of space. Few months ago Dr. Hubble measured the fastest nebular retreat at 24,000 miles per second. That one was 240,000,000 light-years away. No decipherable spectrum of the outpost nebula reported last week was obtained, but. if it follows the rule, it is receding from Earth at 50,000 miles per second...
