  1. Fair enough, well answered both of you! I thought it was gonna be more complicated than that, but I feel a bit of a tool after reading your answers (and actually thinking about it a little)!
  2. That makes sense... I was aware of the balancing act between the inward gravity and the outward expulsion of energy, but never thought about it in the context of a stars birth! Like you say, no doubt there will be some more conclusive answers... But that is an excellent baseline!
  3. I have recently been watching Wonders of the Solar System again and I just wanted to double check something from the first episode. The Professor was explaining how the collapsing, spinning cloud of Hydrogen formed the Sun. But the way he explains it is that the Sun suddenly ignited, lighting up the Solar System. I was wondering, did the Sun suddenly ignite when it hit a certain mass (when the core was hot/dense enough to begin to fuse Hydrogen atoms under pressure), or did it gradually get hotter and hotter as more and more Hydrogen was pulled into the Sun as its gravity increased, gradually expelling more and more light and heat?
  4. Very good point Macavity... I remember a point in the previously mentioned Horizon programme when one of the guys working on the James Webb 'scope said there were multiple countries working together to make it successful (I forget the figure but it was in the tens, it wasn't just 3 or 4)! Anything that brings countries together (especially in the environment of scientific development) has to be positive!!
  5. I'm with the general consensus on here. The money spent on Hubble has been vitally important in growing our understanding of the universe and what makes it so complicated/fascinating! To be brutally honest, I hadn't heard of the James Webb telescope until the Horizon programme on BBC2 on Monday (15th August... iPlayer if you missed it) but they should absolutely get that thing where it belongs! ... In an effort at remaining neutral, aren't we all moderately biased toward any sort of space programme
  6. I only live in Congleton and I don't recall ever seeing it... Although now I know there's the possibility I'll be concentrating a lot more!
  7. Ah, I have a '4, so hopefully the results should be even crisper with the extra MP'age... Once this cloud clears, obviously!
  8. Is there a Mac equivalent of the MS ICE program? I've always wondered how these mosaics are made, and it seems like ICE does a dam fine job!
  9. That is very impressive, and an ingenious method of photography... What iPhone do you have?
  10. I have fingers crossed, although I don't like the thought of crossing them until the supernova happens... I may get cramp!
  11. Good explanation, and I had no idea so little of the initial Hydrogen fuel was used during the stars lifetime. The fact that so much Hydrogen is expelled during the stars life and death goes a long way to explaining how the resulting nebula can produce so many new stars. Thats my question initial answered... I feel well and truly enlightened!!
  12. That hadn't even entered my mind... That literally is a once in a lifetime thing isn't it, Orion disappears for the Summer, and comes back in the Winter after being on a diet and loosing a squillion kg's and a limb!
  13. I've heard that before, brings back memories from my Physics A-level, memories it's taken me years to repress Woohoo! I'll be an Astrophysics... Guy... Thing before you know it!
