Popular Mechanics SA's video: Red Moon rising on 15 April 2014

An extraordinary string of four total lunar eclipses is about to illuminate our skies starting on 15 April 2014. In the early hours of tomorrow morning, our pale Moon will turn blood orange red. This spectacle will mark the first of four consecutive total lunar eclipses, a series known as a tetrad. A lunar eclipse occurs when the Moon dips behind Earth's shadow. Most eclipses are partial, meaning only portions of the Moon are hidden from the Sun. But sometimes the Moon, Earth and Sun perfectly align so that the entire Moon is shielded from the Sun's rays. When this happens, wayward beams of sunlight filter through Earth's atmosphere, colouring the Moon a fiery red, resulting in a total eclipse. The total eclipse of 15 April 2014 will be followed by another on 8 October 2014, another on 4 April 2015, and another on 28 September 2015.
