A lunar tetrad – four total lunar eclipses in a row – begins on the night of April 14-15. People are calling it a Blood Moon eclipse. Here’s why.

On the night of April 14-15, the planet Mars - closest in 6 years - will be near the eclipsed moon.  The star Spica will also be nearby.  Illustration via Classical Astronomy.

The first Blood Moon eclipse in a series of four is coming up on the night of April 14-15, 2014. This total eclipse of the moon will be visible from the Americas. We in astronomy had not heard the term Blood Moon used in quite this way before this year, but now the term is becoming widespread in the media. The origin of the term is religious, at least according to Christian pastor John Hagee, who wrote a 2013 book about Blood Moons.

Meanwhile, both astronomers and some proponents of Christian prophesy are talking about the upcoming lunar tetrad – the series of four total lunar eclipses – beginning on the night of April 14-15.

We at EarthSky don’t have any special knowledge about the Blood Moons of Biblical prophesy. But, since they’re moons, and since people are asking us, we wanted to provide some info. Follow the links below to learn more about Blood Moons.
