Show More Nebulae Charted in Sky Clusters in Space Mapped by Survey HUNDRED new clusters of a nebulae great masses of gas and stars at incredible distances out in space have been discovered by the new Schmidt telescope at Palomar Photographs of the new clusters taken with the Schmidt Sky Survey telescope and the Hale telescope at Palomar have furnished new data to astronomers implementing the theory that the entire universe is expanding at speeds comparable to the speed of Distant clusters never before seen the farthest some million light years away have been found to follow the of Milton Humason of the Palomar Observatory staff disclosed to his colleagues of the Astronomical Society of the They range out to the extreme observable limit of the Schmidt and finding more distant clusters beyond the reach of the Schmidt must hereafter depend upon pure Humason Only about 20 such massive systems in space were known prior to the start of the National Geographic Observatory Sky Survey in The others have been found in the last two the amount by which light from star clusters is moved toward the red end of the spectrum indicate to astronomers In what direction a nebulosity is The red-shift brought about formulation of the basic theory of an universe about a quarter of a century the affords astronomers a measure of the speed at which trier members of tho universe are rushing away from the Earth's own solar system |
