DMNS+field+trip2

What was the best part of the field trip? The best part of the field trip was the planetarium. What are the two facts that you learned?that a long time ago, a huge collision killed the dinosaurs. what I also learned which was pretty cool was that in some years away from now the milky way and another galaxey will crash into each other but won't hurt any planet but will just mix up the dust and gases in it.
