Exciting times in astronomy just now - not that I'm able to keep up with it all. Can't seem to link it But there's a good piece on cnet. Keplars cool as well.

Yes, saw an item on this, quite an achievement!

Incredible. Voyager 1 seems to be moving at about 30km/s looking at the distance counter. See here.

Yeah I remember reading and watching Carl Sagan when I was a Kid in the 70's , 30 odd years later and his work is still going strong.

How wonderful, mankinds first fioray across interstellar space is underway, and to think I watched both launches on TV all those years ago. Makes one feel quite humble...

The scary thing that I think about a lot, and which so isolates us from the possibility of coming across other life, is that we would need to be able to travel much MUCH faster than Voyager (about 33,000 mph) to even contemplate interstellar travel. Even the speed of light isn't really fast enough, and we know of no physics that can get us faster, let alone approach it. Time dilation at huge speeds would help the travellers (but not us), but really it would have to be a generation ship. Meaning that the intermediate generation(s) would see neither their home of origin nor their destination. Even then, the problems of cosmic ray radiation and small particles penetrating the ship would be massive hurdles to overcome. Relative to this, a closed bio recycling system is probably within our grasp as is an ion propulsion system. The universe is so mind-numbingly large that the likes of Star Trek are, well, pure fantasy

Yeah it's rumoured that the stealth fighters use ion drive as well and there is evidence of burst pulse technology in use also. Personally I think humans ideas in this field are quite primitive - a big rocket on top of huge fuel tanks!! - and I also dislike the rigidity of our thinking. Being bound by "laws" is nonsense. I'm a firm believer there are other,far more advanced civilisations out there and that the proof is overwhelming. Things like Voyager and Keplar have turned our thinking around in regard to things like planetary formation and what life needs/is.
The burst pulse evidence came from Macrahanish way. Huge,remote airstrip near Campbelltown Scotland.
Future propulsion systems are fascinating.

I also disagree with you MartinT in that instead of travelling fast I think we need to re evaluate how we perceive time and how (if it even exists) it can be manipulated. I do reckon a few scientists do know and have done for years.

What I do know is that the statistics suggest that the probability of other life out there is overwhelmingly positive. That's fine, but it isn't proof.

Let's say someone punched you in the face and knocked you out so you didn't remember. (Let's hope not). There are several highly credible witnesses,CCTV footage,someone's filmed it on their phone,a blokes found with your blood on his knuckles would that suffice as proof?
Exactly the same standards could be applied to various devices that have appeared and science will not accept this level of proof. Why not?
I'm not being a dick here and I accept your point entirely however WHAT level of proof do you need?

A very interesting place once designated by NASA as an emergency put down point for the Space Shuttle due to the length of the runway there. You probably would have enjoyed the article I wrote on the place on a UFO forum I once ran, now sadly defunct but not 'debunked' I will dig it out sometime, dust it off and re-post it on my current site...

Yes, and the key word there is 'credible'.
I'm not the kind of idiot who says "I wasn't there on the moon to witness the moon landings and therefore I don't believe they happened". It's about credibility and weight of evidence.

Yeah and there's plenty of that. The Rendlesham Forest incident springs to mind. A US nuclear base commander and a team of his men? Are they credible enough?
Batteries dieing so gotta go but I will post back later.
I also do not think you are an idiot - please don't take this all wrong.

Cool,cool. I'm sometimes not the best at expressing myself and constantly get in trouble for it. I'm 6ft5 and 18 stone so a lot of folk find my mannerisms,and me,pretty hard going. The grief I get at work over it is unbelievable and holds me back in my career quite badly. Not very much I can do about it though.
Dave,I've been up to Macrahanish a couple of times - it's now part of a community buyout and they're trying to establish a business park there. It was also a US special forces base and there have been recovery operations reported as well as seismic readings that make no sense originating from the area. Circular contrails have also been photographed which led to the pulse burst conclusions.
If anyone's into their cars or scenery then the drive there is just fantastic - takes you right down the Kintyre peninsula with the island of Jura on your right. Stunning.

As this seems to be a thread about things astronomical , here's one of my all time fave pics .....
Seems that the small bright galaxy (the upper one of the 2 small ones) has careened through the larger galaxy and exploded a ring of gas around it, which has created a storm of star creation around the outer edge. The smaller galaxy, too, has been disturbed enough to initiate a burst of star creation.
Amazing stuff.
