Some astronomy aficionados are paying top dollar to catch the upcoming total solar eclipse, but there are plenty of options to take in the rare astrological phenomenon for free.

If you find yourself in the path of totality, you'll want to make sure that you're using eye protection before turning your gaze upward. Experts warn against looking at the obscured sun for "even a split second," emphasizing that the solar radiation can burn the inside of your eyes and potentially cause irreversible damage.
