In Fall of 2021, Boys Republic students were able to use the 100-inch telescope at Mt. Wilson Observatory. The telescope was completed in 1917. At the time, it was the world's largest telescope. Edwin Hubble used the telescope to sow that the universe extended beyond the Milky Way galaxy. Students spent the evening with the telescome-staff beding introduced to the history of and viewing of planets, including Jupiter and Saturn, and distant galaxes, millions of light years away.
