The Voyager I spacecraft has left our solar system and entered interstellar space. This was in the news last year, but the loss of an instrument in 1980 kept them from being sure. Now they have been able to confirm it using other on board instruments. The probe is now 17 light hours from Earth. That's about three times the distance to Pluto.
