Just rented Space Cowboys this weekend and enjoyed it but had two questions, the second of which is only implied by the movie:
1. I know from reading the moon-hoax debunking about why it is logical to NOT see stars in the background in photos on the moon. But in Space Cowboys there are several shots around the large satellite they're trying to repair in which the background stars are highly visible. Should they not have been?
2. How does heat propagate in a vacuum? Specifically, I know that if I stand beneath the exhaust of a spaceship when the engine fires, I'll be fried. But what if I stand off to the side just a few feet so that the plume of flame travels next to me but doesn't touch me. Will I still get fried or will no heat travel across the vacuum sideways to me? Did I write this clearly enough?
Thanks for tolerating the astronomically illiterate such as myself, but this is why I come to this board. I know it's not a big deal to most on this board, but it's because of lurking here that I was able to point out Mars to my kids when we went on vacation this summer.
