Interstellar Space: NASA

NASA: Thirty-six years after it was launched from Earth on a tour of the outer planets, the plutonium-powered probe is more than 11 1/2 billion miles 18.51 billion kilometres from the sun, cruising through interstellar space the vast, cold emptiness between the stars, the space agency said Thursday, according to Times Colonist. While some scientists remain unconvinced, NASA celebrated with a news conference featuring the theme from "Star Trek." LOS ANGELES, Calif. - Voyager 1 has crossed a new frontier, becoming the first spacecraft ever to leave the solar system, NASA said. Voyager 1 actually made its exit more than a year ago, according to NASA. But it's not as if there's a dotted boundary line or a signpost out there, and it was not until recently that scientists with the space agency had enough evidence to say that the probe had finally plowed through the hot plasma bubble surrounding the planets and escaped the sun's influence.
