Voyager left solar system last year, new research shows


NASA's long-lived Voyager probe crossed into interstellar space last year, becoming the first man-made object to leave the solar system, new research shows.

Scientists have been waiting for Voyager to detect a magnetic field that flows in a different direction than the solar system's magnetic field. But the new research shows that scenario is not accurate.

"We think that the magnetic field within the solar system and in the interstellar are aligned enough that you can actually pass through without seeing a huge change in direction," University of Maryland physicist Marc Swisdak said in an interview with Reuters on Thursday.

That would mean that Voyager actually reached interstellar space last summer when it detected a sudden drop in the number of particles coming from the sun and a corresponding rise in the number of galactic cosmic rays coming from interstellar space.

Not everyone is convinced, however.

  1. This sort of information helps breakdown the boundaries of the “thinking in boxes” which simplification of natural systems tends to build in minds.
    The Solar system is part of a continuity of matter and energy in our local spiral arm of the Milkyway, in a similar way to which a species is part of the coninuous spectrum of life.
    Like life, the galactic disk has gaps between its visible arms, but these are not necessarily empty, simply because their contents are less numerous or less visible!

    The Milkyway has smaller satellite galaxies, and will as part of cosmic evolution, collide and merge with the giant Andromeda galaxy in 3 – 5 billion years time.

  2. I think the big news is that according to your illustration Pluto is a planet again 🙂 Clyde Tombaugh rules!
