NEW YORK CITY (CNN) – The longest total lunar eclipse of the century arrives Friday night, showcasing a blood moon for most of the Eastern Hemisphere. This picture taken on July 27, 2018, shows the moon during the total lunar eclipse, in the Cypriot capital Nicosia.

It started in Australia and Indonesia. The lunar eclipse happens during daylight hours for those in the Western Hemisphere, so people in North America will miss it. Lunar eclipses can occur only during a full moon, and this one is extra special because it’s also the blood moon. The moon will be in perfect alignment with the sun and Earth on Friday, with the moon on the opposite side of the Earth from the sun. WATCH BELOW: Livestream of the Lunar Eclipse   The totality of this lunar eclipse will last about an hour and 43 minutes, but a partial eclipse before and after the total phase means the moon will spend nearly four hours crossing the Earth’s shadow. When the full moon moves into Earth’s shadow, it will darken, but it won’t disappear. Sunlight passing through Earth’s atmosphere will light the moon in a dramatic fashion, turning it red. Depending on the weather conditions in your area, it may be rusty, brick-colored or blood-red. This happens because blue light undergoes stronger atmospheric scattering, so red light will be the most dominant color highlighted as sunlight passes through our atmosphere and strikes the moon. “The moon is not always in perfect alignment with the sun and the Earth, so that is why we do not get a lunar eclipse every lunar cycle,” Brad Tucker, an astronomer with the Australian National University’s Research School of Astronomy and Astrophysics, said in a statement. “You will see the sunrise and sunset of the Earth lighting up the surface of the Moon — over 350,000 km away. If you were on the Moon, you would see a total solar eclipse as the Earth would be blocking the Sun.” This full moon in July is also known as the Full Buck Moon and the Thunder Moon, occurring when a male deer’s antlers are in full growth and at a time of frequent thunderstorms, according to the Old Farmer’s Almanac. It’s also a “mini-moon” because the moon is the farthest from Earth and appears small. The fact that the moon appears so small and takes longer to pass through Earth’s shadow is also why the eclipse lasts longer. Viewing the eclipse So where can you see the total lunar eclipse? People in Australia, New Zealand, Europe, Africa and Asia will have the best view, while the final stages of the eclipse after sunset will be visible in parts of South America. For those in the Middle East and Madagascar, the eclipse will occur about midnight, and people in Europe and Africa will have the best view between sunset and midnight. Asia, Indonesia and Australia will see it between midnight and sunrise Saturday. Priscila Sinaga captured the moon’s reddish hue during the blood moon eclipse in Cinere, Indonesia. Dennis Doucet climbed a mountain behind his house in hopes of getting some photos of the full blood moon rising over Osaka, Japan, on Friday night. He captured a photo of an airplane flying in front of the moon as it came in to land. The Royal Astronomical Society said Mars and the moon will appear low in the sky for everyone in the UK, so a location with an unobstructed southeastern horizon will afford the best view. EarthSky.org has a map showing more exact locations, and TimeandDate.com has timings based on your location. North America, much of the Pacific Ocean and most of the Arctic won’t see a thing. The entire United States won’t be able to see a full lunar eclipse again until January. The Virtual Telescope Project will share a live stream of the lunar eclipse and Mars at its brightest just a few degrees apart above the skyline of Rome. Slooh, a robotic telescope service, is livestreaming the eclipse beginning at 10 a.m. Pacific time and ending at 4:30 p.m. Eastern time. And unlike solar eclipses, especially the total solar eclipse in August 2017, the lunar eclipse is safe to view with the naked eye or binoculars. Mars in the sky Our red moon will have some company Friday, when Mars is the closest to Earth that it’s been in 15 years. Mars is reaching its opposition, when it’s in alignment on the opposite side of the Earth and the sun. This occurs at the same time that it will reach one of its closest points to the Earth, about 35.9 million miles away. This is what makes it appear so brightly in our sky, beginning early Friday morning. While Mars will be overhead for people in central Chile, South African and Australia, it will be low in the southern sky for those watching in the U.S. and Europe. “Despite its glorious girth, northern observers will pay a price during this juicy Mars apparition,” Sky & Telescope contributing editor Bob King said. “At most perihelic oppositions, including this one, the planet retreats to the belly of the ecliptic low in the southern sky.” Mars will actually be at its closest approach since 2003 on Monday and Tuesday, when it is 35.78 million miles away. So if bad weather disrupts your opportunity on Friday, there will be more chances. Experts estimate that Mars’ brightness will persist for several weeks. Mars’ closest approach will be at 1 a.m. Pacific time Tuesday, according to EarthSky.org. Although it won’t look nearly as large as the blood moon, Mars will be its largest if you’re looking through a telescope and close to its maximum brightness in our sky. Mars is also safe to view with the naked eye. The-CNN-Wire & © 2018 Cable News Network, Inc., a Time Warner Company. All rights reserved.
