Of the 7.4 billion people on Earth, about 7 billion people could - in theory - see the eclipse, except for those in North America and Greenland, where time of day didn't allow.
Telescopes will be set up for public viewing and astronomy talks will be conducted free of charge at the venue.
At the same time, Mars is travelling closer to Earth than it has done since 2003, so some observers may see what looks like an orange-red star - and is in fact the red planet. In Ethiopia's capital, Addis Ababa, people at an open-air restaurant admired a rare clear view during the rainy season, comparing a live NASA webcast to what they saw above.
A combo of six pictures shows a "blood moon" total lunar eclipse in Bishkek late on July 27, 2018. It's called a "blood moon" because it turns a deep red and will be visible at different times around the world. This means the sun's light is blocked by the Earth, and the moon passes into its shadow. In metro cities, space enthusiasts may miss out on watching the moon being eclipsed due to pollution.
When the full moon moves into Earth's shadow, it will darken, but it won't disappear.
The July 2018 lunar eclipse will be the longest one till June 9, 2123.

Skywatchers will be focusing on the moon this weekend to watch the longest total lunar eclipse of the century, also known as a blood moon.
Mars added to the wonder on Friday night as it appeared directly below the blood moon at near maximum brightness.
"The blood moon is definitely a prophetic sign [of the end times]", one prominent YouTube preacher (whom Live Science prefers not to name) said in a recent video. The red hue is caused by rays of sunlight refracted by Earth's atmosphere.
It won't be visible in the US, but can be seen in parts of Africa, the Middle East, Europe, South America, Australia and Asia - depending on the weather. The lunar eclipse in India will start at around 10:44 pm on Friday and stay till around 2:43 am.
When the sun, Earth and moon are all lined up, sun-rays shine on the edges of the Earth.
"The earth's atmosphere then turns the light red in the same way that the sun appears when it is going down", Prof Fabian said.
