Starting April 15, 2014, we will get to see something that has happened three other times in the last six centuries.
The lunar eclipse is a phenomenon where the sun, Earth and moon align and the Earth moves between the sun and the moon. When this happens, the Earth’s shadow is cast on the moon.
Here in Sydney, Australia except for Western Australia, you can catch the closing stages just after moonrise on the evening of April 15. And lucky for us, the “blood moon” is completely safe to view with the naked eye.
The lunar eclipse is also known as the ‘blood moon.’ The moon takes on a reddish, copper color during the event thanks to the refraction of sunlight through the Earth’s atmosphere. Refraction is also the reason why we have blue skies during the day and red sunsets in the evening.
The tetrad, meaning group of four, means that there are four lunar eclipses in a series that will happen over a relatively short period of time. The first of these is April 14th/15th. The other three will be in October 2014, April 2015 and September 2015.
