Bad Astronomy Post

     A comet has a tail behind it that could contain sand, ice, and rock.  I was right by writing this down as a true fact, becasue that's really what follows behind a comet while orbiting in space.  Another fact that I put down underneathe the true facts was that the astronot was blinded and that his skin was so badly burned by the suns light.  I was right for the fact that the suns rays can damage your eyes, and if your close enough u can be burned by it, but being that far away from the sun in the movie he should not have been injured that badly.
     In the movie there were also things that were false, one was that you wouldn't be able to hear any noise on the comet, becasue there isn't any air in space.  So i was right about that one.  Another thind that was false in the movie was that you can't walk on an astroid like you would do on earth, because of the gravity difference, so i was right also when saying that was wrong.
     A misconception that people think about stars at night are that all stars emit just white light, and honestly I head heard that they didn't, but I still thought that they just let off white light.  That was wrong because it turns out that all stars give off all the colors of the rainbow.
