Bad Astronomy Post

In our class we watched Deep Impact. We were to write down notes which were factual or wrong in the movie. I thought that the Sun would burn your eyes if you didn't have protection, I was right in that it would hurt your eyes if you didn't have some type of protection, like the astronaut in the movie, but a moment of exposure would not have burned his face as bad as it did in the movie. A fact they had in the movie that I thought was wrong was that they can walk on the comet, and i was right. You would only weight 12 grams, You would fly off the comet by just running. A factual thing they said in the movie was about the stars they were observing, Mizar and Alcor which are actual stars. A non-factual thing was in the end the exploded the second comet, one you cant explode a comet with a few atomic bombs, it would take 100s just to maybe move it a faction if that. Also say they did explode the comet the kinetic energy from the comet would destroy the atmosphere.
The article I read was All the Stars are White. I kinda knew stars were different colors. It was interesting to read how they could be all colors of the rainbow depending on the heat of the star. Really hot stars are mostly blue. And cooler stars are mostly red. It was interesting to read.
