1.) Why have observers on Earth never seen craters on one side of the moon?

2.) How do equinoxes and solstices differ?

3.) How would the moon appear to an observer in space during its revolution? Would phases be observable?

4.) Which of the moon's motions are real? Which are apparent? Explain why each occurs.

i mean it is where our future is headed. one of these days we will outgrow the earth or do something that will make it unfit for human life, and there are many things we get back from space missions. i read that for every $1 spent on NASA the US gets $7 back. i know that NASA has had a couple of unfortunate incidents recently, but surely that can't overshadow all the good to come from space travel! if you are one of the ones that feels like space exploration is a waste, i want to know why!

Why aren't the images of stars in color (blue or orange)? Is it because of the telescope? Or are most telescopes unable to show color images?

I have the 10" itscope and love it,you made a great choice!
The views I get from Detroit Mi are wonderful. The DSC's work great in cold weather too.These apertures start to show you the colors of the stars and planets. The dbl. star catalog choices are awesome and to see the colors of these stars is a welcome change to the greenish colors of neb/galaxies. I align mine by racking in the focus w/ the 25mm until I see the out of focus rings and position the align. star in the center.I've also glued 2 sm. bubble levels from aco onto the base so I know if I'm on level ground, even if my warp factor is 0.5 it's still gets my object in the field of view at low power.Good luck with the new scope,if U have ?'s plz post them here and hope to hear how you like it, I may upgrade!

Science tells us that everything in existance is held within the universe, that which came into being one cold night in 11,254,647,011 B.C. (lol... I made that part up).

Do you think space goes on forever? That's a hell of a long ways ya know. Or... eventually does it just curve backaround on itself? If so, if it is just a big round ball, what is it contained within?

Of how about the old cosmology approach by good old Steven (Hawkins). That our universe could simply be an atom in some other, much larger existences universe... Or that an atom under our fingernail could be a universe for some civilization that evolved quickly? We wash our hands and whoooosh... God just initiated the biggest flood imaginable...

Don't these questions just hurt your mind?

So, follow the expanding universe back through time and you get to a singular point some 10 - 20 billion years ago. Not very long ago really.

If you keep up on theoretical physics and astronomy you will see that in 100 billion years every star will be so far apart that were you to look up (although the Earth would have died 98 billion years earlier) you wouldn't see a single star. In 100 trillion years everything in existance will cease to exist. There will be no light... only individual protons floating millions of miles apart from one another.

So considering that everything must cease to exist, and assuming that everything has obviously existed forever... What the hell was before the big bang? I don't need string theory or the, "Time didn't start until the big band"... yadda yadda yadda.

Do you think that there have been endless big bangs? If we just exploded one day from something the size of an ink dot could there theoretically be another one tomorrow from a dot by mars?

3. The star Sorius appears to be about ten times brighter than Deneb. Yet scientists have found that Deneb gives off much more light than Sirius. Why is this?


4. Why is a light year (distance light travels in a year) a useful unit for measuring distance to stars?



at least answering 1 would be helpful, thanks in advance!!!

I personally think the universe is finite, despite the meaning of the the word "universe." Sounded by an infinite empty space in which other possible universes (on our plane, not going into quantum physics). Share your thoughts!

I know Earth's rotation affects the seasons, but does Earth's revolution around the sun affect the seasons?
