On the morning of our harvest festival we had a special guest speaker. It was Mr.Gianforte. Mr.Gianforte is an astronomer and came to talk to us about a new subject in astronomy. The new astronomy was about exoplanets. Exoplanets are planets that we find out of our solar system. We found one with livable qualities, yet it is so far away the we would not be able to get there, but in the future there might be a possibility to try. Another thing that he talked about was the size of different planets and he compared a few picture and described some scale as well.
