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.
Lunar Eclipses (the darkening of a full moon by the shadow of the Earth) occur every 6 months, and total lunar eclipses normally come in sets of three, followed by three partial eclipses. The lunar eclipse of June 26, 2010 is a partial eclipse visible mainly in Australia.
