Trip to observatory

 On the 28th of  June the senior syndicate went to the Hamilton obervatory which was right next to Hamilton zoo. The weather was being nice so we can look through the telescope. At the observatory I learnt that the sun is not yellow it's mostly white. I also learnt that a house is part of a street, a street is part of a town, a town is part of a place, a place is part of a country, a country is part of  planet, a planet is part of the solar system, a solar system is part of a galaxy, a galaxy is part of the universe.       
One question i still have, Is there planets in the other galaxys?
