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.
NASA says lunar eclipses typically happen at least twice a year, but this eclipse is the third in a series of four in a row, known as a tetrad.. The first was on April 15, 2014. The second was in September 2014, the next is Saturday and there will be one more, on September 28.
