Scientists had announced earlier that Voyager 1 had left the solar system, however the Voyager team has issued its own statement.
According to Space.com's updated story:
The scientists still don't know for sure, however, whether the probe has entered interstellar space or a mysterious in-between region beyond the solar system.
According to the Voyager team at JPL:
Voyager 1 is within a new region called 'the magnetic highway' where energetic particles changed dramatically. A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change of direction has not yet been observed."
