The spectrum of the sun has hundreds of strong lines of iron but very weak lines of helium. A star of spectral type B has strong helium but very weak iron lines.

Why does NASA roll the space shuttle out to the launch pad so early before a launch? I think it would be safer for them to wait until maybe a week before launch to protect it from the elements, not the 3 or so weeks that they do.

OK,
I've thought many times about the infinity and I ended with several ideas and what is worse...more paradoxes than ideas.:

1. Is the universe born from the Big bang? - No.
Several galaxies, including ours are born from the Big bang but not the entire world...this is just because, before the big bang there was another big bang...and so and so on...Also its impossible one hing to exist for a boundless time and then just to explode...

2. If the universe has always been around what does this mean?-
Well I think thats the most interesting part. If we assume that our world has no beginning and no end....that means that probably out there some alien civilizations are so evolved that they are not only
billions of years better than us, but boundless years...

3. Is the infinity a real thing or just an idea?
Well, I think our world is not exactly "infinite". If two things have always been moving to the opposite way one from another...that means that they will meet each other.

I know that the closer you are to earth, the faster you have to travel to orbit the earth. So how high is the International Space Station? P.S: If you haven't seen Astronaut Farmer w/ Billy Bob Thorton, go see it....its a good, motivational/inspirational movie...I think!

If a constellation is a zodiac constellation of near the zodiac band It can only be seen during a specific season, or else it will be hidden by the sun or present during the day (not visible). And since Orion rises and sets, it goes east to west, it cannot be a near polar star. So it should be seasonal, but it seems that I can see it for most of the year. I live within the tropical belt.
