First off, if I were to ever become a supervillian, I’d want my name to be Heliopause. Just ‘cause.
Voyager 1, launched 33 years ago, is now approaching the edge of our solar system.
Scientists know the craft has reached such a point by observing a change in the particles that surround it. These particles, emanated by the sun, are, instead of travelling outwards, are flowing sideways. This means that the particles are shifting in order to go down the tail of the heliosphere, which is indicative of Voyager 1 making the jump into interstellar space.
Around the heliosphere is the heliosheath, in which temperatures rise and wind speeds slow to zero. Scientists are measuring particle speeds around Voyager 1 to be nearly zero, thus they believe this is where the craft is. It is suspected that it will make the cross-over in the next few years.
The initial goals for Voyager 1 (and its sister Voyager 2) was to survey the outer planets Jupiter, Saturn, Uranus, and Neptune (and Pluto, too, back then I guess). This was accomplished back in 1989. Now it’s breeching the outermost reaches of our star.
How freaking cool is that?
