Although total lunar eclipses happen relatively often, the one happening on Friday 27 July 2018 is particularly special because it will last for the longest time of any such eclipse in the 21st century.
When the three celestial bodies are perfectly lined up, however, the Earth's atmosphere scatters blue light from the sun while refracting or bending red light onto the moon, usually giving it a rosy blush. But supermoon eclipses can make the natural satellite appear even darker than it does during other total lunar eclipses.

"The reason that the moon turns red is because atmospheric scattering causes red light to pass through the atmosphere and the composition of the atmosphere can change if volcanic eruptions or forest fires occur", said Tom Kerss, an astronomer with the Royal Observatory Greenwich. This is when the moon is completely inside the Earth's shadow and is the most spectacular part of the lunar eclipse.
Astronaut Alexander Gerst tweeted: "A partially eclipsed Moon, with our neighbouring planet in the background, just before diving into Earth's atmosphere". A period of complete eclipse, known as "totality", will last from 3:30 p.m.to 5:13 p.m. ET.
