25 YEARS AGO: A REALLY BIG SHOW
Astronomers gather in the New Mexico desert to dedicate the Very Large Array telescope on October 10, 1980. The radio telescope’s 27 antennas work as a single instrument to allow detailed imaging of objects as near as our solar system or as far as the most distant quasar, 12.8 billion light-years away. Today the VLA produces more discoveries annually than any other ground observatory.
180 YEARS AGO: WATER WEDDING
New York governor DeWitt Clinton takes the inaugural voyage on the Erie Canal, leaving Buffalo for New York City aboard the packet boat Seneca Chief, October 26, 1825. The 363-mile canal, eight years and $7 million in the making, links Lake Erie to the Hudson River. At the end of his nine-day trip along “Clinton’s Folly”—he had predicted the canal would create “the greatest inland trade ever witnessed”—Clinton pours a barrel filled in Lake Erie into the Atlantic in a “wedding of the waters.” His prediction is on the mark: shipping costs drop by 90 percent, settlers flood west and the canal pays for itself in nine years.
