HARVARD, Mass. — With the touch of a lever, "E. T." director Steven Spielberg launched a search for real extraterrestrials Sunday, turning on a giant antenna that astronomers hope will detect radio signals from outer space.
"This marks the beginning of a really powerful search that has a decent chance of finding something," said Paul Horowitz, a Harvard University professor who designed the 84-foot communications dish, part of the most powerful radio-scanning system ever used to hunt for aliens.
