Many parts of the globe may catch a glimpse on Wednesday (Jan 31) of a giant crimson moon Becky Sauerbrunn World Cup Jersey , thanks to a rare lunar trifecta that combines a blue moon, a super moon and a total eclipse.
""The last 'blue moon' total lunar eclipse visible from the US and North America happened on March 31, 1866.""
The ""blue moon"" aspect simply means it is the second full moon in a month, not that the moon will appear blue. A blue moon happens on average just under every three years.
It's called a super moon because the moon, in its elliptical orbit, is near its closest point to Earth.
This proximity, or perigee Alyssa Naeher World Cup Jersey , makes it appear 14 per cent bigger than normal and 30 per cent brighter.
The reddish tint - or blood moon - happens due to ""the effect of all the sunrises and sunsets all around the planet reflecting off the moon, which I think is really lovely,"" said NASA astrophysicist Michelle Thaller.
Sunrises and sunsets appear pink, red and orange because of the long distance light must travel, causing light waves to bounce in different ways, explained Thaller.
""The reason a sunrise or a sunset is red is the sunlight has to pass through a large amount of air on the side of the Earth and that actually scatters away any blue light and just lets the red light come on through,"" she said.
HOW TO WATCH
The blood moon will not be visible in much of Europe Allie Long World Cup Jersey , Africa and South America.
Viewing will also be a challenge for those on the US East Coast, since the eclipse begins just as the moon is setting in the west and the sun is rising in the east.
But those who are not in the path of totality, or who are experiencing cloudy weather, may catch it anyway, via a live stream broadcast on NASA.gov.
Moon-watching parties for the one-hour-16-minute eclipse were advertised up and down the US West Coast, including at Griffith Observatory in Los Angeles, where the gathering kicks off at 3.45am.
If you miss this one Ali Krieger World Cup Jersey , the next blue moon total lunar eclipse will happen on Dec 31, 2028, though it won't be quite as large since the moon will not be at its closest point to Earth.
Another will happen on Jan 31, 2037, a total of 17 hours before perigee.
""The red colour during a lunar eclipse is very distinctive and it's a rare treat to be able to see a blood red moon,"" said Brian Rachford, associate professor of physics at the Embry-Riddle Aeronautical University.
""One of the great things about a lunar eclipse is you also don't need any special equipment to see it. Anyone can go outside and look at the moon.""

NEW YORK, Sept. 21 (Xinhua) -- U.S. financial service agency S&P's decision to downgrade China's credit ratings will have little impact on investor sentiment as it underestimates the country's capacity to curb debt risks and deepen economic reform, experts have said.
The agency on Thursday lowered China's sovereign credit rating by one notch to A+ from AA-, citing economic and financial risks from China's fast credit growth.
LIMITED IMPACT
"The move by S&P ... is likely to have little impact on investor sentiment," Tom Orlik Abby Dahlkemper World Cup Jersey , Bloomberg's chief Asia economist, told Xinhua Thursday.
Khoon Goh, head of Asia Research at Australia and New Zealand Banking Group Limited, said, "There shouldn't be much impact judging from the market reaction following the Moody's downgrade a few months back."
The markets were generally undisturbed by rating agency Moody's move to lower China's credit rating in May.
Since Moody's decision, the Shanghai Composite Index has kept a bullish momentum, breaking above a ceiling at 3 USA World Cup Jerseys ,300 points at the end of August.
The Chinese yuan has also regained strength and soared to one-year high against the U.S. dollar in August. The Australian dollar, liquid proxy for China-related trades, rose more than 6.6 percent against the greenback since May.
China's stock markets were closed Thursday when S&P made the announcement, and there was little reaction from the yuan.
Experts attributed the market optimism to investors' belief that the fundamentals of the Chinese economy are stable and rating agencies have overestimated the difficulties in managing debt risks.
"The cuts (by) Moody's and S&P don't really reflect the international investors' view on China's economy," Wang Tao, chief China economist at UBS Group AG in Hong Kong, told Bloomberg.
Wang added that risks have been reduced Whitney Engen World Cup Jersey , corporate profits are rising, shadow financing has been reined in and capital outflows have been contained.
"(The downgrade) is pretty behind the curve," she said.
CONTROLLABLE DEBT RISKS
Experts believe debt risks are manageable in China with its fiscal firepower, minimal foreign debt, and abundant foreign reserves.
Brad Setser, senior fellow at the Council on Foreign Relations, a U.S. non-profit think tank Tobin Heath World Cup Jersey , said it is important to recognize that China's external balance sheet remains strong.
