==Explanation==
{{incomplete}}
''{{w|Voyager 1}}'' is a U.S. space probe launched in 1977 to study the outer reaches of the Solar System and beyond. Popular press has on several occasions announced that it "has left the solar system" -- at each point when a boundary has been confirmed or a major event has taken place -- the fact is that the boundary is not known for sure, and that there are too many "authorities" who declare the major event of first man made object leaving the solar system entering into interstellar space. The Alt-text refers humorously to one of these being the US Census Bureau who have absolutely no authority in these matters.

The boundaries mentined in the title are:

* the termination shock - the point in the heliosphere where the solar wind slows down to subsonic speed (relative to the star) because of interactions with the local interstellar medium ([http://en.wikipedia.org/wiki/Heliopause_%28astronomy%29#Termination_shock wikipedia])
* the heliopause - the theoretical boundary where the Sun's solar wind is stopped by the interstellar medium (see [http://en.wikipedia.org/wiki/Heliopause_%28astronomy%29#Heliopause wikipedia])
* the heliosheath - the region of the heliosphere beyond the termination shock ([http://en.wikipedia.org/wiki/Heliopause_%28astronomy%29#Heliosheath wikipedia])
* heliosphere - a region of space dominated by Earth's Sun, a sort of bubble of charged particles in the space surrounding the Solar System,
* heliodrome - a [http://en.wikipedia.org/wiki/Heliodrom_camp concentration camp] in the bosnian war
* auroral discontinuity,
* Heaviside layer - a layer of ionised gas occurring between roughly 90–150 km (56–93 mi) above the ground in the Earth's atmosphere
* trans-Neptunian panic zone - this fictional zone combines the word from two subject: "trans-neptunian" is used in astronomy to describe stuff that occurs beyond neptune. In [http://en.wikipedia.org/wiki/Outdoor_education] the "panic zone" is the opposite of the [http://en.wikipedia.org/wiki/Comfort_zone comfort zone] when trying to learn new stuff.
* magnetogap - part of an [http://en.wikipedia.org/wiki/Ignition_system ignition system]
* US Census Bureau Solar System statistical boundary - this may refer to the concept of a "statistical area" in geography: an area around a city where people live who commute to that city, for example a [http://en.wikipedia.org/wiki/Core_Based_Statistical_Area core based statistical area]
* Kuiper gauntlet - this is a mixup: the [http://en.wikipedia.org/wiki/Kuiper_belt kupier belt] is region of the Solar System beyond the planets, extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun. A gauntlet is a tough glove used by sword fighters.
* Oort void, a gigantic "cloud" of materials (mainly composed of ice) which ends around a light-year from The Sun and is deemed the (current) "edge" of the solar system.([http://en.wikipedia.org/wiki/Oort_cloud])
