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.
Itâs rare to have 7 eclipses in a calendar year. Itâs less rare to have 7 eclipses in 365 days. There are 7 eclipses in 365 days 29 times in the 21st century! A solar eclipse happens at new moon, when the moon passes between the sun and Earth.
