I love this kind of stuff, and have recently been reading/researching the topic a fair bit in my spare time.

Anyway, the tiny dot visible in the middle right of the picture below is the Earth photographed from 3.7 billion miles away by the Voyager 1 in 1990 as the spacecraft was leaving our solar system.

Pretty awesome in my opinion. I think if anything highlights our potential as a species, it's our advancement in space travel and understanding of astronomy after 200,000 year of existence - and it's all happening now. If we figure out how not to destroy ourselves imagine what we could achieve in another 200,000 years.

The idea of developing a spacecraft that can possibly travel up to 1/10th the speed of light has been hypothesised and worked on for a while, from atomic detonations in space to fusion rockets. Or are we reaching the boundaries of mans abilities with the resources we'll ever be able to work with? Some scientists argue travel to other solar systems may be beyond the limits of humans, largely due to the vast distances that need to be covered and our life spans

The subject of interstellar travel is incredibly fascinating, and this geek* highly recommends it for those interested in the stuff.

*all because Apollo 13 was my favourite film as a child, honestly!

Amazing!

They can have a picture sent back from 3.7 billion miles away and they still can't come up with a decent pic of your local bank robber.

I am still waiting for warp drive (http://en.wikipedia.org/wiki/Warp_drive) to become a reality....much better than travelling through sub space (remember event horizon).

Science fiction leads to the next science theories and hopefully something more real...

We need some decent power sources then who knows what...

It's a bit like how Osama bin laden managed to send video messages to the west... from a cave.... in afghanistan... yet o2 can't seem to deal with me sending or receiving text only messages from my house in York.

Other stuff worth looking at re: space.

The most important image ever taken. The Hubble Ultra Deep Field. Ignore the cheesy music, if this doesn't have an impact on you there's something wrong with you. https://www.youtube.com/watch?v=fgg2tpUVbXQ

Are you sure they haven't just got a bit of crud on the sensor and didn't want to own up to it?

Voyager hasn't yet left the solar system. It's currently in the outer section known as the heliosheath.
