First off, a Blue Moon means that there are two full moons within the same month. However, it also takes on the distinction that it is the fourth moon in a season that normally has only three full moons. So there you go - we have sorted two out of the three!
Next, a Blood Moon? Sounds scary right - like it should be coming from a horror movie or something. But there is another explanation.
This full moon is going to also be an eclipse. There is a lot going on with this one moon on these few nights at the end of January, so a lunar eclipse is one in which the moon appears darkened as it passes into the earth's shadow and the earth's curve filters out the blue light in the spectrum and the moon takes on a reddish glow.
What else is cool about this, is the last time it happened was 1866 - over 152 years ago. It will not occur again until the year 2028.
This particular astronomical phenomenon, in this specific combination, will be visible from Australia and will last about 1 hour and 16 minutes.
So you will be able to go stand outside in the darkness on January 31, 2018 and watch this most amazing of occurrences.
You should plan a party, share this amazing event with your family and make it a big deal - because it truly is!
Do you remember when the Hale Bopp comet passed so close to the earth in 1997? It was so close to the earth, you could see the tail and watch it for great lengths in the night sky as it passed by. We still remember. Why? Because we made sure that our kids knew what was going on and it is something that we shared with each other.
