Space

So like just after the united states and the USSR 'finished' their space race, the result being that the US made it to the moon before the Russians did, we sent out a spacecraft that was going to go and take pictures of Saturn. This ship was only supposed to go on a five year trip and then after it they would send it into the planet where it would be crushed after falling miles into the planet. They decided to just send it away from the sun.
First I should say that this Ships name was Voyager 1, and it competed its Saturn mission with fantastic results.

From this Mission we learned that Saturn, just like Earth, has an Aurora that happens at its polls.

But what i want to get to is that after this mission we just sent this ship out and pointed it away from the sun, and just recently NASA made an announcement that as of August 2012 this ship has left the heliosphere.
The heliosphere is the electromagnetic sphere the sun creates. It is just like the one that our earth makes, and because of our stars heliosphere the planets don't get bombarded with interstellar radiation. And now that this ship has left our Solar System it can be argued that our race(humans) have become interstellar beings, though we did it kinda by cheating as this ship took around 36 years to do it. Anyway (did you know anyways is not a 'real' word as its slang) this ship is going to keep going and at its current speed it will reach the next star in 44,000 years. so just have to wait a bit longer.
