For about three hours, Voyager 1 left the solar system. Voyager 1, one of two spacecraft NASA launched in 1977 on a grand tour of the outer planets, is now nearly 11.5 billion miles from the sun, speeding away at 38,000 miles per hour. The American Geophysical Union, publisher of the journal Geophysical Review Letters, sent out the news that scientists were reporting: "Voyager 1 has left the solar system." NASA officials, surprised, issued a statement from scientist Edward C. Stone saying: "Voyager 1 has not yet left the solar system." The geophysical union then sent out another e-mail, saying: "Voyager 1 has entered a new region of space."
