Space wreck!

I am new to planet minecraft and I wanted to make something but I didn't know what to do. So I researched some thing I could do and I came up with this. I plan on making many more things in the future so your support would be appreciated.

The pic is about a spaceship getting hit by a meteor and crashing down to earth with only the front end surviving. But, what is that mysterious fragment on the top? In the comments I would like for you to post what you think it might be. In my next posted project I will realease what it is.
