Candles are a leading cause of home fires and fatalities. Soot on the walls and furnishings is unsightly, and may also be a sign of serious problems. It may also be unhealthy, as inhalation of minute particles of soot has been documented to cause health problems.
It is a popular misconception that the phenomenon of a total eclipse of the sun is a rare occurrence. Quite the contrary. Approximately once every 18 months (on average) a total solar eclipse is visible from some place on the Earthâs surface. That's two totalities for every three years.
Typically there is 1 total eclipse every 1 to 2 years. Although it is possible to have 2 total eclipses in a single year, it is quite rare. Examples of years containing 2 total eclipses are 1712, 1889, 2057 and 2252. The table below lists every solar eclipse from 2014 through 2020.
