If the moon looks bigger than usual Saturday night/Sunday morning, it is not your eyes playing tricks on you.

Saturday's full moon is what is known as  an extreme supermoon.

The full moon will occur while the moon is at its closest point, 212,000 miles, to Earth in almost 20 years. NASA says the moon will appear to be much larger than usual and will bring with it larger than normal tides.

Some people say the supermoon is a sign that global chaos, such as earthquakes, storms or unusual climate patterns are coming. In the recent past, we have seen super moons  in 1955, 1974, 1992 and 2005. In all of those years there are examples of extreme events; however, most scientists debunk the theory.

Scientists have said that the Japanese earthquake cannot be blamed on the supermoon.  On a side note, on Friday, March 11, the moon was at almost its furthest point from the Earth.
