An anonymous reader writes "Yesterday, Voyager 1 passed 100 astronomical units from the sun as it continues operating after nearly 30 years in space. That is about 15 billion kilometers or 9.3 billion miles as it travels about 1 million miles per day. Scientists still hope it will find the edge of the solar system and get into interstellar space."
