Question by HH: How many eclipse are there going to be this year?
I was just reading on NASA website that there are going to be four eclipses in 2012? Is there going to be one by Venus? If I live in Texas will I see all of them?

How to calculate the declination of the Moon?
Question by Montana B: How to calculate the declination of the Moon?
I would like to be able to predict the date of the next lunar eclipse, either via calculator or via a VB.Net program. I already have the declination of the Sun nailed down, so this is the only other thing I would need to make a prediction.
Great post, but I was kind of hoping maybe someone would have a simpler way to calculate this, maybe i'm too lazy but the algorithm seems a little long.

Answer by bikenbeer2000It might be easier to work with ecliptic longitude and latitude, rather than right ascension and declination. That way, the latitude of the Sun is automatically zero and you only need to search for times when the Sun and Moon are 180º apart in ecliptic longitude, with the Moon's latitude less than 1º 37', which means an eclipse is possible. Don't forget that, for lunar eclipses, you're only interested in geocentric positions of the Sun and Moon. For an observer on the Earth's surface, the Moon's coordinates can vary by up to 1º from the geocentric position. Some formulae for the Moon's coordinates are given at this website: http://stjarnhimlen.se/comp/ppcomp.html
[Later]
You could shorten the algorithm, but you would lose accuracy. Referring to the website, if you ignore the perturbations of the Moon, you probably wouldn't miss the dates of many lunar eclipses, but the calculated time might be up to 4 hours out. When writing a program, these perturbation terms can be added as a subroutine, since this stage of the calculation is essentially repetetive.

Are we supposed to sacrifice a chicken or a goat to bring back the sun disk? Or an enemy captive? Or do we send money to a televangelist?

Question by Michael: Is something going to happen between May 20th, 2012 and June 6th or just after?
I know the solar eclipse is going to happen on may 20 , 2012 but I just saw video saying that theirs going to be a big earthquake and that Nostradamus and Mayans predicted something was going to happen. Is it true what is really going to happen in 2 days I know the solar eclipse but anything else? Should I be worry about? Is the world going to end on December 21, 2012 ? I'm really scare right now

Answer by Vic RattleheadYes, the people that lived 1400 years ago predicted the exact date of the exact natural disaster of something that will happen in a place they didn't even know about at the time using the stars.

The Mayan calendar ends December 21, 2012. It's the end of something called the Long Cycle. As soon as it ends, a new one begins. They just didn't record it. It's like the end of the year. The world doesn't end when there are no more days in the year, a new year just starts instead.
