There's no place like home

A visual celebration of the home planet, starting with a view from Earth as seen from Saturn — 870 million miles away — and zooming in close On the morning of the first Earth Day, on April 20th, 1970, a friend and I boarded the IRT subway line in Brooklyn and headed for Manhattan. Our destination: Fifth Avenue, where New York City's festivities were to take place. I don't recall ever having heard the term "home planet" back then. Yet the basic idea already had great currency, thanks
