in class discussion

I thought the discussion about space was so intresting. It was amazing to see the different galaxies because they all looked so pretty. What also struck me was how long it actually takes us to notice that has something that has happened in space. I didn't know that it takes us 8 min for us to notice the sun has changed so we are actually looking at the past. It is also amazing how many different galaxies there are. There might actually be other life forms out there studying about us just like were studying about them.
