미국에서는 152년 만에 볼 수 있는 달 쇼 4붕주를 오늘 밤 관찰 할 수 있을 것이라고 나사가 발표하고 있다.
4중주라 함은 수퍼문, 불루문 , 불러드분과 개기월식이 동시에 일어나기 때문이다.
Blue Moon, 음력과 양력의 시차로 인해 한 달에 두 번 뜨는 달.
Super Moon, 달과 지구의 거리가 가장 가까워져 크게 보이는 달.
Blood Moon,또는 Red Moon, 지구에 가리워서 태양 광이 붉게 달에 반사되어 보이는 달.
그리고 개기 월식.
이런 4가지 현상을 대략 밤 11시부터 6시 사이에 동시에 관찰할 수 있을 것이라고 한다.
우주 개발의 꿈이 눈앞으로 다가오고 있는 오늘날 달의 신비는 이미 벗겨지고 있다고 하겠지만 이런 종합 달 쇼는 생애 한 번
볼까 말까 한 행운이 될것 같아 보 아둘만 하기는 할것 같다.
A rare super blue blood moon that has not been seen by much of the world for more than 150 years has been gracing the world's skies.
A 'super blue blood moon' is the result of a blue moon ? the second full moon in a calendar month ? occurring at the same time as a super moon, when the moon is at perigee and about 14 per cent brighter than usual.
It also combines with a blood moon ? the moment during a lunar eclipse when the moon, which is in the Earth's shadow, takes on a reddish hue.
While people in the eastern Hemisphere saw their last Blue Moon total lunar eclipse in 1982, for the Western Hemisphere, the eclipse was the first blue moon total eclipse since 1866.

A rare super blue moon is currently rising in the sky over the UK. A super blue moon is the result of a blue moon ? the second full moon in a calendar month ? occurring at the same time as a super moon, when the moon is at perigee and about 14 per cent brighter than usual. Pictured is the moon behind the Walkie Talkie building in London
As well as a supermoon, the spectacle is a blue moon, defined as the second full moon in a calendar month. UK astronomy enthusiasts looking to see the blue moon at its top-most point will have to brave the cold and windy weather. Pictured is a plane flying in front of the moon in London
Dr Gregory Brown, an astronomer at the Royal Observatory Greenwich, said after the moon has risen at around 5pm GMT today it would remain in the sky until 8am GMT tomorrow morning. Other parts of the world have experienced a 'super blue blood moon', in which the super blue moon combines with a blood moon. Pictured is the moon above London
Those in the UK expecting to see a lunar eclipse will be disappointed, as Dr Brown has said it will 'definitely not be visible from the UK, not even a partial eclipse'. Pictured is the moon above London, with St Paul's Cathedral in the foreground
Dr Daniel Brown, an astronomy expert from Nottingham Trent University, told MailOnline that when the moon is quite low in the horizon - for instance when it is rising or sinking past the horizon - the atmosphere of the earth will redden it (pictured) independent of an eclipse.

'It's an astronomical trifecta,' said Kelly Beatty, a senior editor at Sky and Telescope magazine.
'That red light you see is sunlight that has skimmed and bent through Earth's atmosphere and continued on through space to the moon,' said Alan MacRobert of Sky and Telescope magazine.
'In other words, it's from all the sunrises and sunsets that ring the world at the moment.'
While much of the world has experienced a 'super blue blood moon' today, the moon above the UK this evening is just a super blue moon.
This occurs when a blue moon occurs at the same time as a super moon, but without also combining with a blood moon.
The moon sets behind the Statue of Liberty in New York. . This is the last one in a series of three consecutive 'Supermoons', dubbed the 'Supermoon Trilogy'
The previous 'Supermoons' appeared on 03 December 2017 and on 01 January 2018. A 'Supermoon' commonly is described as a full moon at its closest distance to the earth with the moon appearing larger and brighter than usual. Myanmar, pictured

UK experts suggest the moon, having risen above Britain at 5:00pm GMT, will remain in the skies until 8:00am GMT tomorrow.
Despite the UK not experiencing a lunar eclipse, and therefore missing out on a blood moon, many pictures seem to show the satellite glowing red.
Dr Daniel Brown, an astronomer at Nottingham Trent University, told MailOnline this is because when the moon is quite low in the horizon - for instance when it is rising or sinking past the horizon - the atmosphere of the earth will redden it independent of an eclipse.
A lunar eclipse occurs when the sun is on the other side of the Earth while the moon is located on Earth's opposite side.
The super blue blood moon is pictured behind the Statue of Liberty in New York. The event began at 10:51am UTC (10:51 GMT, 05:51 ET) with the full lunar eclipse starting at 12:51 am UTC (12:51 GMT, 07:51 ET) and reaching its maximum at 1.29pm UTC (1.29pm GMT, 08:29am ET)
The partial eclipse is seen just above the horizon in Washington DC. The darker part of Earth's shadow began to blanket part of the moon with a reddish tint at 6:48 am EST (11:48 GMT)
The moon is pictured behind the Staten Island Ferry, seen from Brooklyn
People watch the super blue blood moon over Brooklyn. While people in the eastern Hemisphere saw their last Blue Moon total lunar eclipse in 1982, for the Western Hemisphere, this eclipse will be the first blue moon total eclipse since 1866
'Most of the time the full moon sits above or below Earth's shadow and the moon remains flooded with sunlight', explains Dr Tanya Hill, an Honorary Fellow of the University of Melbourne, writing for The Conversation.
'But twice a year, the three bodies fall into line so that Earth casts its shadow on the moon.'
The Earth's shadow is not completely black but has a reddishy hue, which has led many cultures to describe it as a blood moon.
Sunlight manages to reach the moon but first it has to pass through Earth's atmosphere.
This makes the sky redder (as it scatters away shorter shorter wavelengths of light) and also bends the path of the light, directing it into the shadow.
Unlike a solar eclipse, this lunar eclipse can be safely viewed without protective eyewear.

'We've had a lot of super moons and we've had lunar eclipses, but it's rare that it also happens to be a blue moon,' said Jason Aufdenberg, associate professor of physics and astronomy at Embry-Riddle Aeronautical University's campus in Daytona Beach, Florida.
'All three of these cycles lining up is what makes this unusual,' he added.
'It's just a wonder to behold.'
The first super moon of this year appeared on 1 January.
Lunar eclipses during a super moon happen rather regularly and the last one was in September 2015.
Lunar eclipses occur at least twice a year while super moons can happen four to six times a year.
A rare super blue blood moon - which might look similar to this large orange moon spotted rising over Griffith Park in Los Angeles - is gracing the world's skies. When the moon is nearer the horizon, moonlight must pass through more atmosphere than when it is overhead, which is why the moon sometimes appear orange

The incredible celestial event turns the moon a reddish hue as the lunar eclipse happens. Pictured is the super moon rising behind the Saffron Square building in Croydon ahead of this 'unusual' event
The next super moon lunar eclipse visible throughout all of the United States will be January 21, 2019 - though that one will not be a blue moon.
A full moon occurs every 29.5 days, but our months are longer (excluding February).
This mismatch of timing means that every couple of years there comes a month with two full moons.
According to experts from Nasa, the event will also offer experts a chance to see what happens to the moon when it cools quickly.
This information will help them understand characteristics of the regolith ? the mixture of soil and loose rocks on the surface ? and how it changes over time.

'The whole character of the moon changes when we observe with a thermal camera during an eclipse,' said Paul Hayne of the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder.
'In the dark, many familiar craters and other features can't be seen, and the normally nondescript areas around some craters start to 'glow' because the rocks there are still warm.'
Normally, the transitions into and out of darkness and the temperature changes that go with them, are spread over the course of a lunar day (29-and-a-half days).
'During a lunar eclipse, the temperature swing is so dramatic that it's as if the surface of the moon goes from being in an oven to being in a freezer in just a few hours,' said Noah Petro, deputy project scientist for NASA's Lunar Reconnaissance Orbiter, or LRO, at Goddard Space Flight Center in Greenbelt, Maryland.
From the Haleakala Observatory on the island of Maui in Hawaii, the team will conduct their investigations at invisible wavelengths where heat is sensed.
They've done this kind of study a few times already, singling out individual lunar locations to see how well they retain warmth throughout the eclipse.

Experts believe the last time a super moon, blue moon and total lunar eclipse were all visible at the same time was from the eastern United States was on 31 May, 1844
How quickly or slowly the surface loses heat depends on the sizes of the rocks and the characteristics of the material, including its composition, how porous it is and how fluffy it is.
By comparing the two types of observations, the team is able to look at variations in particular areas ? say, the lunar swirls at Reiner Gamma or an impact crater and the loose debris around it.
This kind of information is useful for practical purposes such as scouting out suitable landing sites. It also helps researchers understand the evolution of the surface of the moon.
'These studies will help us tell the story of how impacts large and small are changing the surface of the moon over geological time,' said Dr Petro.
