[Related: Everything To Know About the January 2019 Lunar Eclipse] Original Article: There have been some spectacular lunar and solar eclipses over the past few years, and next month brings another show for stargazers to check out. The next total lunar eclipse will occur on July 27, 2018. A lunar eclipse occurs when the moon passes through Earth’s shadow, at which point it takes on a reddish tint, which is why the eclipse is colloquially called a "blood moon." You won't want to miss this eclipse, as it will be the longest total lunar eclipse of the 21st century, lasting one hour and 43 minutes. The total eclipse will take place from 7:30 p.m. UTC (3:30 p.m. Eastern) until 9:13 p.m. UTC (5:13 p.m. Eastern). The moon will be partially eclipsed for roughly an hour before and after the total eclipse, and the maximum eclipse will occur at 8:22 p.m. UTC (4:22 p.m. Eastern).

It will be the longest of the 21st century. It will be visible to people living in the Eastern Hemisphere. North America will not be able to see it. The longest total lunar eclipse this century will adorn the Eastern Hemisphere's night sky at the end of July, but the U.S. will miss out on this one. On the night of July 27-28, the Earth will completely block the sun's light on the surface of the moon for a total lunar eclipse that will last a full 1 hour and 43 minutes, making it the longest of the 21st century, Earth Sky reports. The moon will remain under the earth's shadow for a total of 4 hours. The last lunar eclipse on Jan. 31, 2018, which was known as the Super Blue Blood Moon eclipse, lasted 1 hour and 16 minutes. The longest possible total lunar eclipse is 1 hour and 47 minutes. From the eclipse's start to its finish, the moon will take 3 hours and 55 minutes to cross the Earth’s dark umbral shadow. Advertisement Astronomers say the eclipse lasts so long because it will pass directly into the darkest region of Earth's shadow. The eclipse will be visible to people living in the Eastern Hemisphere, meaning Europe, Africa, Asia, Australia and New Zealand. North America, most of the Arctic and much of the Pacific Ocean will miss out entirely, Earth Sky reports. (MORE: What Exactly is a Super Blue Blood Moon Total Lunar Eclipse?) Madagascar and the Middle East will have the best view of the eclipse around midnight. Europe and Africa can view the eclipse during the evening hours, while most of Asia, Indonesia and Australia will have the best view in the morning. The next total lunar eclipse on Jan. 21, 2019, will last 1 hour and 2 minutes.<doc-sep>Skywatcher Giuseppe Petricca took this image of a "supermoon" total lunar eclipse on Sept. 27, 2015, from Pisa, Italy, about 2 minutes prior to the beginning of the totality phase. The longest total lunar eclipse of the 21st century takes place this Friday, July 27. The total phase of the "blood moon" eclipse of July 27 will last 1 hour and 43 minutes, during which Earth's natural satellite will turn a spectacular red or ruddy-brown color. From start to finish, the entire celestial event will last nearly 4 hours. The eclipse won't be visible to viewers in North America, except via webcasts. But observers in much of Africa, the Middle East, southern Asia and the Indian Ocean region will get an eyeful, given cooperative weather, according to lunar scientist Noah Petro, of NASA's Goddard Space Flight Center in Greenbelt, Maryland. [In Photos: The Rare Super Blue Blood Moon Eclipse of 2018] July's total lunar eclipse occurs on the same day the planet Mars reaches its opposition, when it will shine at its best in the night sky. This month, Mars will be at its closest to Earth since 2003. After opposition, when Mars will be brightest, it will reach that closest point on July 31. You can learn more about that event in our dedicated guide here: Mars at Opposition 2018: How to See It and What to Expect What is the Blood Moon of July 27? Unlike with solar eclipses, you need no special equipment to observe lunar eclipses. These latter events, which occur when the moon passes into Earth's shadow, are safe to view directly with the naked eye, telescopes or binoculars. The moon turns deep red or reddish brown during eclipses, instead of going completely dark. That's because some of the sunlight going through Earth's atmosphere is bent around the edge of our planet and falls onto the moon's surface. Earth's air also scatters more shorter-wavelength light (in colors such as green or blue); what's left is the longer-wavelength, redder end of the spectrum. Where and when will it be visible? The timing if this total lunar eclipse means it won't be visible from North America, though much of the Eastern Hemisphere of Earth will see part or all of the eclipse. The entire eclipse will be visible from Africa, the Middle East and countries in central Asia. The eclipse will be visible from eastern South America as it is ending, and from Australia as it is beginning. The time of greatest eclipse will be 4:21 p.m. EDT (2021 GMT) on July 27, according to EarthSky.org. The total eclipse will last from 3:30 p.m. to 5:13 p.m. EDT (1930 to 2113 GMT). There will also be some time before and after when the moon is in the lighter part of Earth's shadow, which is called the penumbra. Including that penumbral time, the eclipse will last for 3 hours and 55 minutes. [Total Lunar Eclipse This Friday: How to Watch Online] On July 27, 2018, a total lunar eclipse will be visible from South America, Europe, Africa, Asia and Australia. This NASA chart by eclipse expert Fred Espenak shows details and visibility projections for this “blood moon” eclipse. (Image credit: Fred Espenak/NASA GSFC) Why is it the longest of the century? "What controls the duration of the lunar eclipse is the position of the moon as it passes through the Earth's shadow," Petro told Space.com. The darkest part of Earth's shadow is called the umbra. You can picture the umbra as a cone extending from Earth in the opposite direction to the sun, Petro explained. "The moon can either graze through the cone, or go right through the middle. That [the middle] gets a longer-duration eclipse," he said. "This time, the moon is passing closer to the center of that cone, and it's therefore a little bit longer than the eclipse we had back in January." [Here’s How Friday's Superlong Lunar Eclipse Works] Additionally, the moon will be at a farther point from Earth along its orbit, EarthSky pointed out. That means the moon will appear slightly smaller in the sky and will take a little bit longer to go through Earth's shadow. Petro is also the project scientist for NASA's Lunar Reconnaissance Orbiter (LRO), which has been orbiting the moon for nine years. It is best-known for obtaining detailed information on water ice and taking high-resolution pictures of spacecraft on the lunar surface. Because LRO is an older probe, most of its components (except for battery warmers and the like) will be turned off during the eclipse, to preserve the solar-powered spacecraft's battery and keep it safe during the greatest part of the eclipse, Petro said. When is the next lunar eclipse? The next total lunar eclipse visible from North America will occur on Jan. 21, 2019. Totality on that day will last 1 hour and 2 minutes, and the eclipse will especially favor viewers on the West Coast. That year will also see a partial eclipse, on July 16, 2019 — the 50th anniversary of the launch of the first moon landing mission, Apollo 11. LRO will likely still be operating then, having passed its 10th anniversary of arriving at the moon on June 23, 2019.

Clocking in at one hour and 43 minutes, the July Blood Moon will be nearly 40 minutes longer than the Super Blue Blood Moon eclipse on January 31 this year. In addition to the total eclipse, the moon will be partially eclipsed for about an hour before and after the main event. In total, stargazers will be treated to about four hours worth of eclipse goodness. According to Noah Petro, lunar scientist at NASA’s Goddard Space Flight Center, the length of the eclipse is dictated by the position of the moon when it passes through Earth’s shadow. Next month the moon will pass close to the centre of Earth’s shadow, or umbra, making it last longer. The shadow cast by the sun extends like a cone out into space from the Earth. Dr Petro told Space.com: "The moon can either graze through the cone, or go right through the middle. That gets a longer-duration eclipse. Eclipse 2018: The July Blood Moon will rise on July 27 this year “This time, the moon is passing closer to the centre of that cone, and it's therefore a little bit longer than the eclipse we had back in January.” The moon can either graze through the cone, or go right through the middle Noah Petro, Goddard Space Flight Center On top of this, the moon will be at its farthest orbital point from Earth which means it will take slightly longer to escape the umbra. But how exactly does all of this cause the Blood Moon eclipse to change colour to a deep red? During the eclipse, the moon ought to disappear from sight completely but scatted sunlight paints the moon red to orange instead.

Play slideshow EPA 1 of 43 Total Lunar Eclipse, also known as a Blood Moon in Vietnam The unusual effect is known as Rayleigh scattering and is the same explanation for the colour of the sky and sunsets. Rayleigh scattering filters out certain bands of colour when sunlight bends around the planet’s atmosphere and scatters the light in the air. Red and orange bands on the visible spectrum are least affected by this phenomenon which causes the eclipsed moon to change colour, thus the Blood Moon nickname. According to data from NASA’s Goddard Center the Blood Moon eclipse will only be visible in certain parts of the world.

NASA explain how a BLOOD MOON occurs Eclipse enthusiasts around the globe are excited to know the Blood Moon lunar eclipse will take place next month on the night of July 27. And the good news is the Blood Moon eclipse will completely outshine every other lunar eclipse for the next 82 years. The eclipse is so special because it will be the longest Blood Moon of the century, clocking in at one hour and 43 minutes. During the eclipse, the moon will dive into Earth’s shadow and take on a deep red hue thanks to sunlight scattered in Earth’s atmosphere, which has earned it the Blood Moon monicker. Stargazers can watch the total Blood Moon eclipse from Eastern Africa and Central Asia and watch a partial eclipse over Western Africa, Eastern Asia and South America. How to watch the Blood Moon Eclipse 2018 in the USA The total lunar eclipse is expected to begin about 3.30pm EDT and last until about 5.13pm EDT. The Blood Moon will be also partially eclipsed for about an hour just before and after the main event takes place, meaning it will last about four hours from start to finish. But the bad news is the eclipse will not be visible from the United States and Northern America this year. Astronomer Bruce McClure of EarthSky.org, said: “This lunar eclipse is primarily visible from the world’s Eastern Hemisphere. “South America, at least in part, can watch the final stages of the eclipse just after sunset July 27, whereas New Zealand will catch the beginning stages of the eclipse before sunrise July 28. Eclipse 2018: The Blood Moon will rise on the night of July 27 next month Eclipse 2018: The total lunar eclipse will make the full moon turn red “North America, most of the Arctic and much of the Pacific Ocean will miss out entirely.” The only hope left for stargazers is to seek out online broadcasts of the lunar eclipse on the night. Robotic telescope service Slooh live streamed the January 31 Super Blue Blood Moon lunar eclipse and will likely announce a Blood Moon eclipse stream closer to the day. Space agency NASA also chimed in with its own live broadcast of the event on NASA TV and could do a repeat on July 27.

It is the longest lunar eclipse of the 21st century Affelia Wibisono, Royal Observatory Greenwich This means the eclipse will begin from the moment the moon rises, which in the case of London will happen at about 8.50pm BST. The astronomer told Express.co.uk the moon will look really big, red, and hang close to the horizon. She said: “It will be visible all over the country which is nice to see and I believe it is the longest lunar eclipse of the 21st century.” The eclipse will begin in the eastern skies and by about 12.30am BST the moon will have sailed high up to the southern skies.
