New Space Concepts Emerge in Survey WASHINGTON-A new and revo lutionary picture of the universe is slowly emerging in the series of 2.000 photographs of the sky being made from a California mountain top by the National Geographic Society-Palomar observatory sky survey. Dr Rudolph Minkowski, re search astronomer at the Cali fornia Institute of Technology, pre pared for the recent international geographic congress in Washington a paper telling of the survey's progress. An important aspect of the urn dertaking. Dr. Minkowski re ported. is the knowledge it will provide for astronomers and physi cists of the place of gas and dust in the galaxy, of which the solar system is an extremely tiny part. "Then content of gas and dust is intimately connected with the structure and the stellar content of a stellar system," Dr. Minkow ski wrote. He added that the sur vey will give "a complete, new, and in some aspects revolutionary picture of the structure and dis tribution of gas and dust in the galaxy . . . "The survey shows the picture of this distribution over the whole sky to a depth of 250.000.000 light years, the most complete infor mation obtainable with present day techniques, and thus contrib utes an essential step for finding an answer to the question whether the large scale distribution in space is uniform or non-uniform."
