I'm really interested in making and assembling my own telescope but I find it difficult to look for materials and a simple step by step procedure. I tried to surf the net but I found telescopes that are so hard to make and with so expensive materials. I hope you can give me simple guidelines or tips on how to make one. Thanks in advance.

when astronauts go up, they fly in US space shuttles, but are there Russian space shuttles? If not do the Russians always fly up on US shuttles? I saw that Russia discontinued their shuttle program in 1993, so whats the deal?

What would you view God, as if a new specis from outer distant galaxy arrive here on Earth.

Like in the game Halo

How would it affect you in the view of God?

It says: The ecliptic marks the position of the sun on the celestial sphere throughout the year. Why is the ecliptic tilted relative to the celestial equator? Also, how would a planisphere be constructed for observers at the North Pole? Where would the sky window be and how far would it extend? Please help!!

... what will be the peak wavelength of the spectrum of a star that emits twice the sun's flux of energy?

a) 2.1 x 10e-7 m
b) 4.0 x 10e-7 m
c) 5.0 x 10e-7 m
d) 1.0 x 10e-6 m

I know I have to use Fsun = r T^4 then use Wein's law. but my answer doesn't match any of the above answer. i somehow got 1.45 x 10e-3

Is it possible the earth had 2 moons one that was smaller. The orbit of the smaller one decayed causing it to crash into the earth. This should create enough trama to the enviroment to cause mass extention. Looking for scientific probablity. My Six year old wanted to know why the earth only has one Moon. Could it have had more?
