...only a blurred dot on a photographic plate. But as displayed last week by Astronomer Rudolph Minkowski of California's Mount Wilson and Palomar observatories, it was a scientific milestone: the dot, probably the collision of two galaxies 6 billion light years away from earth, represented the most distant phenomenon ever identified...
...picture, taken by Minkowski with Palomar's giant 200-in. Hale telescope, was a dramatic symbol of a surge in astronomical science made possible by a far-sighted alliance between optical and radio telescopy. When Palomar's 200-incher was completed in 1948, no one expected it to photograph galaxies more than i billion light years away. A major reason: in such telescopes the field of view is very small, and to reach full range they must take long-exposure pictures of each tiny spot before moving on to the next. Thus, Palomar cannot range the heavens...
