"The total lunar eclipse will be the first visible in North America in three years".
A lunar eclipse is a celestial incident where the moon appears darkened as it passes into the earth's shadow. "The Jan. 21 total lunar eclipse will be the last one until May 2021, and the last one visible from the United States until 2022".
Right now, clouds could be over parts of Arizona, including the Valley, on Sunday night.
You'll be able to see the first hints of the eclipse at about 9:30 PM Eastern Time on Sunday as the moon slides into the penumbra (the Earth's shadow). Usually, the slightly tilted path means the full moon still gets some light from the sun.
While we get two to five supermoons every year, the gap between blood moons is anywhere between six months and three years.
Alle said the lunar eclipse would, by 4.33am, become a partial eclipse, where the moon would start getting red.
The January Full Moon will turn blood-red on the morning of Monday, January 21, here in the UK.
Walter Freeman from the Physics Department at Syracuse University, said: "There are no precautions you need to take when observing a lunar eclipse, since the Moon is never bright enough to hurt our eyes like the Sun is".
Granted permission to stay up past his 8 p.m. bedtime, Gabriel Houging, 8, of Citrus Heights, California, is already dreaming of what he'll see. Also called the Storm Moon and Hunger Moon because of it being at the coldest time of year, the Super Snow Moon may be a good time to get used to going out at dusk.
"You don't have to wait that long for the next lunar eclipse", Jolliff said.
Eclipse totality will end by 5.43am GMT and partial eclipsing will begin. Full moons were traditionally given names by Native American tribes to keep track of seasons. The sunlight that is illuminating the moon has passed through the Earth's atmosphere and is being bent back (refracted) towards the Moon.
The next full moon, known to some as a Wolf Moon, will be a super moon. Earth's orbit around the moon is not perfectly round, so as it circles Earth it is sometimes closer and sometimes farther away, by a distance of about 26,000 miles. So, a super blood moon is an eclipse coinciding with a supermoon. And "wolf" references the fact that the eclipse is taking place in January. The Moon is given the name Super Moon when a full moon comes within 90 percent of its closest approach to Earth. The moon will be at its bloodiest, most super and wolfiest just after midnight.
So why does the Moon appear red?
