NASA voyager 1 officially enters interstellar space

Washington: NASA`s Voyager 1 spacecraft has already entered interstellar space, according to reports.

The model described in the paper is new and different from other models used so far to explain the data the spacecraft has been sending back from more than 11 billion miles (18 billion kilometers) away from our Sun.

NASA`s Voyager project scientist, Ed Stone of the California Institute of Technology in Pasadena, said that details of a new model have just been published that lead the scientists who created the model to argue that NASA`s Voyager 1 spacecraft data can be consistent with entering interstellar space in 2012.

He said that in describing on a fine scale how magnetic field lines from the Sun and magnetic field lines from interstellar space can connect to each other, they conclude Voyager 1 has been detecting the interstellar magnetic field since July 27, 2012.

Stone asserted that their model will mean that the interstellar magnetic field direction is the same as that which originates from our Sun.

He explained that other models envision the interstellar magnetic field draped around our solar bubble and predict that the direction of the interstellar magnetic field is different from the solar magnetic field inside. By that interpretation, Voyager 1 would still be inside our solar bubble.
