2017 Total Solar Eclipse

In a total solar eclipse, the Moon will get between the Earth and the Sun and cast a shadow over Earth.  Darkness will fall in the middle of the day.  Planets and stars may appear.  The temperature could drop up to 5 degrees Fahrenheit (3 degrees Celsius).  Animals and insects may behave like nightfall has set.  You may think you have seen a "total" solar eclipse before, but chances are you have not.  St. Louis has not experienced a "total" solar eclipse since the year 1442 and won't experience another one until the year 2505.
