A total lunar eclipse of "blood moon" in July 2018 is expected to be the longest of this century. It will be long because there will be both a full moon and a simultaneous lunar apogee.

It's always exciting to see a total lunar eclipse in the sky, especially when you think it will be the longest of your life.
What did astronomers discover about the next lunar eclipse?
There will be a full moon and a total lunar eclipse that will take place from July 27 to 28, 2018. It is going to be a "blood moon" and it should be the longest total lunar eclipse of the 21st century.
Earth's astronaut Bruce McClure of EarthSky.org says the eclipse will last one hour and 43 minutes. It will take him nearly four hours to cross the dark shadows of the Earth. This eclipse will last 40 minutes longer than the previous "blood moon" of January 2018. McClure estimates that the total lunar eclipse will include partial eclipses that start at 6:24 UTC, which is 2:24 pm. EST at 10:29 UTC or 18:29. EAST. The eclipse will be visible all over the world.
The total eclipse will include all the bright colors that a "blood moon" would have. It will appear either dark red or orange in the sky. There will also be Rayleigh scattering, which eliminates particles of green and purple light in the sky during the eclipse.
There have usually been two lunar eclipses per year, but not all of them are total eclipses. The following year with two total lunar eclipses is 2022. Some years may also have three or four eclipses.
Why is this particular lunar eclipse so long?
This lunar eclipse is so long because of the day it falls. From July 27 to 28 (depending on where you are in the world), you will see both the full moon and the apogee of the moon, which is the orbital point farthest from the Earth . These two events that occur simultaneously cause the extended lunar eclipse. The longest lunar eclipse can ever occur is one hour and 47 minutes.
"Sometimes called an apogean full moon, or a micro-moon or a mini-moon, this smaller and slower full moon takes longer to cross the Earth's shadow than a full moon that is closer to Earth and move faster into orbit. I said.
What's a blood moon?
A "blood moon" involves a dark red color change on the moon during an eclipse, which is when the moon is completely in the shadow of the Earth. The light waves drawn from the sunsets and sunrises on Earth hit the surface of the moon, giving the "moon of blood" a visible red appearance.
