Aug. 21, 1961 - News of a gigantic explosion in space has just reached earth. A star, perhaps about the size of our sun, suddenly exploded 800 million years ago. But the news has just arrived in the form of brilliant light from the explosion. It took the light that long to get to the earth traveling at 186,000 miles a second. Dr. Fritz Zwicky of Mount Palomar Observatory in California said it was the most distant known supernova, or star explosion, yet observed.
