A result of two rare astronomical events occurring at the same time, a visibly larger, and red-colored moon will appear in the sky. This filtering is caused by particulates in our atmosphere; when there have been a lot of fires and/or volcanic eruptions, lunar eclipses will appear darker and redder.
SpaceWeather (spaceweather.com) explains the red color by pretending you are on the moon: "Imagine yourself standing on a dusty lunar plain looking up at the sky".
When will it happen, and how long will it last?
Sunday's event is also the culmination of a "tetrad" - the last of four successive lunar eclipses that started with the April 15, 2014, eclipse, followed by one on October . 8, 2014, and again on April 4 of this year.
Of a supermoon and a lunar eclipse occurring simultaneously, "It's just planetary dynamics".
The answer for most people is simple: Go outside and look up.
The map below shows the areas of the globe that should be able to see it (barring cloudy weather).
"We have a method, and it works well", science operations planner Dawn Myers, of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.
"Tetrads linked to the Feasts of the Lord and significant Jewish history have taken place only three times in more than 500 years", notes the press release.
This lunar eclipse coincides with a supermoon, meaning the moon will look bigger than usual because it's a little closer to Earth than at other times during its orbit.
Why Will the Moon Look Red? But refraction (not Rayleigh scattering) is the reason that any light reaches the Moon during totality.
Though some observers are viewing the date with fear - calling the eclipse a "blood moon" - for astronomers and stargazers the event is to be welcomed with celebration. This Sunday that process will be complicated.
The curved shadow of the Earth that creeps across the moon during lunar eclipses is key to humankind's understanding of our planet.
The term "supermoon" describes the moon at perigee, when it is about 31,000 miles closer to Earth than at apogee.
The Moon takes an elliptical orbit around Earth, which means that its average distance changes from as far as 405,000km (its apogee) to as close as 363,000km at the perigee. This can only happen during a full moon when the moon is opposite the sun in the sky.
Among the suggested moon foods to be enjoyed while witnessing the blood moon event on September 27, Sunday, which is also the first full moon of fall are mooncakes, pizza moons, moon cookies, Chinese moon pie and Blue Moon burger. Luckily, that nickname isn't a sign of things to come. There's a Supermoon Eclipse on Sunday night into Monday morning-and we're all going to watch it. Here's how, when, and also why to catch the Supermoon Lunar Eclipse. Scientists quickly proved Hagee's theory as false.
