Voyager One has left our solar system but many scientists disagreed when this actually happened. The argument is about "due north" in space. www.msn.com/en-us/news/technology/study-answers-lingering-questions-about-voyager-1-in-interstellar-space/ar-BBmFItP?li=AAa0dzBDo we actually have a "due north" in space? How could we ever figure out a direction in space pertaining to north, south, east, west? Wouldn't Voyager would just be "out there" traveling away from our system to another without a "due north course"? Every system out there would have their own "due north" based on their own individual planets having a north/south pole and the direction would be different on each. I imagine some might even have it on their east west axis somewhere out there. As you can see, I have no clue, and am not a Trekie or a techie. Can anyone help me out? Space. The final frontier..............It covers a big freaking area........ |

Magnetic North and True North on planet Earth are not the exact same thing (nor in the exact same place).  That's just as true in space with the solar poles as it is on the planet. Plus, also as on Earth, the magnetic fields of the Sun are not "uniform" in power or dimension. ADD to that Gravity and the point at which it's no longer felt by an object into the equation, and you can see why it's hard to say EXACTLY where our Solar System stops and Deep Space starts. That's my understanding anyway. I could be entirely wrong though. ETA: And yes... every system would have it's own "due North(s)". Then there's also Galactic North to worry about after that. |

That is the question, how do you determine a true north in space?
There are no east west, north south directions. Up, down, does it exist?
Maybe left or right, straight ahead or turn around and go back, but north or south, I do not comprehend

My best guess is that they're referring to the magnetic field Voyager is still currently traveling through, which would probably be the sun's? Within the solar system with reference to the sun's magnetic field, there is a north and south. So while it's still within the sun's magnetic field, there is a north based on that field.
With regard to magnetic fields, there's always a "north" and "south", so you can look at the magnetic field of a star and take directions from there. In interstellar space where there's literally no magnetic field yeah, I'd think you couldn't really designate a north.
(someone more knowledgeable can hopefully chime in here)

East and West are appropriately related to that pole (just as they are on Earth). |

The final frontier..............It covers a big freaking area........ No, you would have "coordinates" and "headings." Coordinates plot a location, while a heading is the course to those coordinates. A heading is determined by the direction in relation to two 360-degree planes at right angles to each other. You would technically have a left-right, up-down in that system, but it is all numerical between 0 and 360 in both planes. At least that's how Star Trek did it.  |

Navigation in space can also be done based on X, Y, and Z axes. X-axis = Left or RightY-axis = Forward or BackwardZ-axis = Up or Down If you recall, in "ST II: TWOK", Kirk orders the ship to change location based on Spock pointing out Khan's "two dimensional thinking"... Kirk orders "Z minus 10,000 meters", meaning "move the ship along the Z-axis (up and down) down by 10,000 meters". |

The answer by "Elegant_Cow" in this discussion answers your question in the context of Voyager. Regarding "north" generally in space, the situation gets much more complicated when you consider four-dimensional space. Due to relativistic principles, the shape of the universe actually distorts depending on your velocity. The distortion intensifies as you approach the speed of light. |

I didn't think it necessary to clarify that part of it. (And yes, I do recall Star Trek II: The Wrath of Khan.)

I just usually head straight for Jupiter. Then, depending on the time of the Earth year, I either hang a left or a right toward Saturn, but before I even get to her outer moons I turn to head "up" and out past U,N and P.
From there it is Infinity and Beyond baby! No compass coordinates required in space. 
ETA- Earth Come on, man, stick with the program. You had two choices.
1. Second star to the right, and straight on till morning. 2. Out there. Thataway.
We're not doing cartoons here. This is serious stuff!

there is no absolute frame of reference.
none we are aware of, anyway.

LOL... I knew it was "II" and I only actually pressed the capital "I" twice... but sometimes my computer addds a character or two when I do doubles. I miss them occasionally. (see the word "addd", above? I intentionally DIDN'T correct it when it did it...) |
