The term " blood moon " was popularised by Christian pastor John Hagee in 2013 following the release of the book Four Blood Moons , which highlighted a lunar sequence of four total eclipses that occurred in 2014/15.

Skygazers are set for a rare treat today as the longest "blood moon" eclipse of this century will occur in a shortwhile tonight.
The eclipse is estimated to start in India at 11:44pm IST on Friday night and the total lunar eclipse 2018 is expected to begin at 1am IST.

Using the Mars Advanced Radar for Subsurface and Ionosphere Sounding ( MARSIS ), a team of Italian researchers discovered liquid water on Mars . Between 2012 and 2015, MARSIS' ground-penetrating radar conducted a survey of a 120-mile-wide (200-kilometer-wide) zone in the Planum Australe region, just beyond Mars' permanent south polar ice cap.
But a total eclipse occurs only when the Umbra completely covers the moon's surface. The good news is that millions of people around the world - from nearly all of Africa to the vast majority of Asia - will be able to see the moon gradually turn a deep blood red during the total lunar eclipse .
