In the early 1950s astronomer Walter Baade's observations led to a "doubling" of the size of the universe (by recalibrating the distances to objects). Below is a scan (alas, with smudges)of one of the press photos put out for this story in 1953. The photo, taken with the 200-inch Hale Telescope, of globular star cluster M13 (aka NGC 6205).
Here is the caption from the photo:
Globular Star Cluster in the constellation of Hercules. (200-inch Photo)
This was one of the globular clusters studied in the research of Dr. Walter Baade aimed at checking the astronomical distance scale, which he found need an upward revision by a factor of about two. This cluster is known as Messier 13 and is a vast collection of stars. Dr. Baade is a staff member of the Mount Wilson and Palomar Observatories, which are jointly operated by the Carnegie Institution of Washington and the California Institute of Technology.
Mt. Wilson and Palomar Observatories are no longer "married" as they were back in the day. The divorce took place in 1979. M13 however is still there and is a fine object to view through any telescope (especially with skies that do not suffer light pollution) on summer evenings.
