Hi everyone!

I just got a telescope for Christmas. It's been really cloudy though so I haven't been able to use it. Anyway, I was wondering what planets can be seen this time of year. I am in Missouri. I live in the county away from a lot of lights so that shouldn't be a problem. Thanks!

I was in my room a few minutes laying down because I'm sick, I'm also home alone. But I heard something fall in the kitchen and I got scared so I grabbed something heavy and went to the kitchen, when I got there I noticed that this thing we had on the wall had fallen off and flew 9-feet across the room, which I don't see how that's possible! This is not the first time it falls off the wall and it always ends up on the other side of the kitchen. Usually when something falls it just falls straight down but the thing that's on our wall basically flys across the room. And there's other things on the wall so I don't understand why they don't fall off too. My cousin is the person who gave us the item because he got it as a souvenir from the place where he was traveling. Anyway do you think this is some kind of paranormal activity?

Here's a picture of the item:

I think that because nasty poisonous biting things are cold blooded (well apart from ex-wives, but that statement is a matter of opinion) and they had lots of sun, the buggers were free to swan about evolving into more and more nasty things.

How do current theories of terraforming take in account for Mars lack of a magnetic field? Without a magnetic field a planet is ravaged with harmful solar radiation and I watched a documentary that explains this is why Mars has such a weak atmosphere because it is gradually being destroyed by solar radiation.

Next year I planned on taking organic chemistry to fufill my pre med requirements but from what I hear, the course is extremely difficult.

I was wondering what makes organic chemistry so hard? Is the material really that difficult or is it just an insane amount of memorization? Maybe a mixture of both?

And is there anything I can do to prepare for organic chemistry to make my life easier?

Thanks for the help :)!
