One of the world’s most iconic observatories, standing 5,700 feet (1,750 meters) above Los Angeles, is on Mount Wilson. When the wildfire approached the telescopes, there were serious concerns. As shown on the observatory webcam time-lapse video (second slide), suddenly the fire appeared just 500 feet (150 meters) away. But it was a controlled backfire created by firefighters as the last strategic technique to make a barrier to the massive Bobcat wildfire and it worked! The observatory was saved. I have been there several times. It has two of the world’s largest publicly accessible telescopes, where people come to observe the night sky and to host events. The view of the deep sky through these giant, historic telescopes is unbelievable! The 100-inch was the world's largest telescope from its first light in 1917 for three decades. It contributed to science immensely. It is where Edwin Hubble proved the existence of other galaxies beyond the Milky Way and also the expansion of the universe.
