Wildfire Threatens California Observatory

The wildfire raging in Angeles National Forrest outside of Los Angeles, California, is inching close to Mount Wilson, home to the 105-year-old Mount Wilson Observatory. The facility was evacuated on Saturday. The fire has already destroyed more than 42,000 acres of forest and claimed the lives of two firefighters. Now it threatens to destroy telescopes and other scientific equipment worth millions of dollars. Firefighters say they are bracing for a tough battle today.
