This Why Files article discusses newly discovered planets outside our solar system and focuses attention on the question: Are we alone in the universe? Topics covered are: how did scientists discover the planets, what besides planets could they be, the upcoming collision of the solar system with a dense cloud of interstellar gas, and scientists' search for intelligent life in outer space. An update on the planets was posted in July 1998. Six astronomers were interviewed for this article.
