Iy seems like astronomers are still getting light generated by the big bang. Why is this? Its keeping us from seeing the light that is within a certain range of us.

Theoretical yeild ??
Using the follwing information,calculate the theoretical yeild for the dehydration of 3.0 mL of cyclohexanol.

Substance --> molar mass(g/mol) --> d (g/mL)
cyclohexanol --> 100.16 ----> 0.948
cyclohexene----> 82.15----> 0.811

Please don't give me a wikipedia link or a copy-and-paste from there; I don't understand a word of it. Could the black hole actually teleport you somewhere? Or does the object get crushed?

If you have a parabola on a graph and three of the points are...
(1, 19) (-1, 7) (-2, 13)
how can you find the quadratic equation, or function, for that graph?

I always see pictures of the milkyway, often times with a little arrow pointing to a tiny blue dot, which represents the Earth.

Now, these pictures are obviously digital and non-animated or illustrated...

Ok, back to my question: If Earth, and our solar system is INSIDE the milkyway, how are we able to take a picture of the entire galaxy...when being inside it? Do we have photographic satalites that can travel beyond our solar system and transmit pictures back to Earth?

Ok, here's an analogy: The milkyway is represented by a glass of milk (clever, eh?) and the solar systems is represented by the milk (which is contained by the glass.)

Since we're our the milk, how are we able to take a picture of the glass?

I watched Saturn about 3 months ago, but I haven't been able to locate it recently in the night sky. I assume that for at least half the year it is overhead only during the daylight and not visible.

I know this may seem like a stupid question, but please bear with me.

Are there any stars (and I mean text-book stars) located within our solar system, aside from the Sun?

From Earth, the sun is quite large, considering that it's roughly 99 million miles away. After looking at the stars tonight, the brightest I could find (by my trusty naked eye) was obviously much, much less smaller than the Sun.

I don't know what the hell is wrong with my brain. I feel I'm being a complete idiot right now.

[insert shameful expression here]

So are the stars we see in the nightsky located within our solar system, or are they from distant galaxies, or both..?

Of course, then there is the question of how big exactly is our solar system....


I know it's a lot of questions. I've pretty much forgotten everything from grades 1 - 8, please forgive me.

(√3 / √6-1) - ( √3 / √6+1)

Sorry this is correct. The square root of 3 divided by the square root of 6-1. subtract the square root of 3 divided by the square root of 6+
