Astronomy & Space - October 2007

I am in a Science Seminar class for my senior year of 2008 and we have to debate on whether it's a good or a bad deal to go and explore space. I am on the "con" side so I was hoping if I can get some help on this.

Alright here goes this is just a theory with a question in the theory if the question is true I feel the theory is correct.

First the question: When you look in the night sky and see reflected light off of a plant 100 light years away that light is a 100 years old correct? This 100 year light is carrying the information of that plant? If we had a strong enough telescope you would be able to see the plant has it was 100 years ago? I guess the question is more of telescopes if I understand correctly that a telescope magnifies the light? So with this stated if we were able to travel faster than the speed of light, the further you went away from Earth the further back in time you could see?

It’s not a practical application just an idea, any thoughts?

Craters on the moon
Rings around Saturn
and stars.

I don't know much about Astronomy...except a 100 level course. I live in the city and saw Venus in the east, even with 8X25 binoculars could not see m uch.

I looked at Costco website and they range from $69-275 (the most I want to pay is $300.)

What should I look for...or is money spent in this range a waste because quality would be terrible?

NASA claims on their web site the Space Shuttle is the most complex machine ever built by man

Will you be sad to see it retire in 2010 or do you think the worlds first space plane was a waist of money due to the amount of maintenance it requires between launches plus the two memorable trajeties which received worldwide headlines.

Why are different frequencies needed above and below the carrier frequency? Why can't a sound signal simply be sent over one frequency (the carrier). What is the purpose of the carrier anyways?

Is it true that all geostationary satelites are over the equator?
If that is so then their altitude is just governed by their mass?
Would it therefore be true that a satelite broadcasting to Europe would have to be higher than one broadcasting to Egypt, say, in order to see over the horizon

Obviously, if possible, a lunar stationary satelite over the "dark" side of the moon would be undetectable from earth. This could be useful for certain purposes.....

Well... stars and planets make up a galaxy... but then some scientists think that all the galaxies are just scattered around every where... how do we know that millions of galaxies, could make up one super galaxay? and then millions of those could form an even bigger galaxies... so yeah basically... how do we know that galaxies don't cluster together like stars and planets to make a bigger (MASSIVER) galaxy?

How do scientists know that distant galaxies are made of matter and not antimatter?

Antimatter has identical properties as matter so it could form stars and planets too. Light emitted by antimatter stars is exactly the same as light from matter stars. The only thing that we receive from other galaxies is their light. So how can we know if distant galaxies are made up of matter or antimatter?

This is true. I was in a very remote, dark area. We were stargazing and the Milky Way stretched across the sky. All of a sudden, out of nowhere, I saw a pinpoint of light grow many times in magnitude and then snuff out. My question is: Is it possible it was a supernova, or should I be looking closer to home; i.e. a satellite that exploded. How can I check ? How can I report it ? It happened around 7:55pm PST.
