You may have noticed the moon tonight. The full moon tonight was what is called a "Super Perigee Moon." It is as close to earth as it will get in 2011--and it also happens to be a full moon this year. But tonight is more special than most years since this full moon is as close as it has been to earth since 1993.
The next full moon will be April 18th, but today's is 14 times larger and 30 times brighter.
The moon also affects the tides. Though it may be simply coincidence, there was a Super Moon two weeks after the Indian Ocean Tsunami in 2004. This Super Moon, of course, is occurring just after the Japanese earthquake and tsunami.
The next full Super Moon won't happen until 2029. You'll be 18 years older.
