 We started with an image of the Milky Way constructed within the galaxy. Whenever you see any picture of the whole Milky Way from outside the galaxy, remember that it is an artist's drawing. The size of the galaxy is so large that the distance one must travel to see it all is way too far. Here's what I mean. If we assume that our field of view is 140 degrees, we can use trigonometry to find the distance to a point where such a picture could be taken. That point is approximately 301,000 trillion kilometers or 187,000 trillion miles from the Sun's current location. Voyager 1 left on its journey in 1977 and is traveling at 61,000 kilometers per hour or 38,000 miles per hour. It has already gone 21.2 billion kilometers or 13.2 billion miles. If we aim it at the photographic point at its current velocity, Voyager won't reach this point for another 562 million years.
