...telescopes to the path in the skies where he had said his planet would be moving. The night of last Jan. 21, Clyde W. Tombaugh, 24, an assistant at the observatory, saw a strange blotch of light on a new plate. He hastily took the photograph to Vesto Melvin Slipher, director of the observatory. They were quite excited. Here visibly was Percival Lowell's proof. Night after night they rephotographed the planet. Pictures showed that it moved slightly in the same direction as the other planets. This was additional proof. They might have shouted out their find at once...
Wilson and Earle Slipher predicted that the image intensifier would break the Mars deadlock. Last summer when Mars came close, they attached the tube, still imperfectly adjusted, to their comparatively small 24-in. telescope. Even though the "seeing" was extremely bad during the whole period of observation, they got pictures of Mars almost as good as the best ever taken...
...news from Mars-brief as it was−was good. Astronomer E. C. Slipher, of Lowell Observatory, Flagstaff, Ariz., recently returned from South Africa confident that Mars, which often suffers from drought, has had an unusually fruitful year. At any rate, the markings on Mars, which shrink and grow with the changing Martian seasons and are believed to be due to vegetation, are bigger and more intensely colored this year than any Dr. Slipher has seen in his 50 years of Mars-watching...
...Slipher's visit to the Lamont-Hussey Observatory at Bloemfontein was a kind of dress rehearsal for September 1956, when Mars will come closer (only 35 million miles away) than at any time between 1941 and 1971. This year it came fairly close, but it was too low in the southern sky to permit the great telescopes of the Northern Hemisphere to observe it effectively. Since there are few observatories in the Southern Hemisphere, most of the world's Mars-watchers are waiting impatiently...
...written. However, the story tends to give an inaccurate idea by saying that this effect was "first discovered by Hubble . . . and that on it he based his startling theory of the expanding universe." In reality, I believe you will find that the redshift was first observed by V. M. Slipher of Lowell Observatory. Hubble, however, was the one to notice the law connecting the amount of the shift and the distance of the nebulae...
