Total lunar eclipse on July 27: What you need to know

Skywatchers in North America will not be able to see the rare event and will have to wait until 2020 to experience a total lunar eclipse.

Sometimes called a blood moon, a total lunar eclipse occurs when the Earth moves directly between the sun and the moon. The entire event - beginning as the moon passes through the Earth's stratosphere - will last about six hours and 13 minutes, Petro said.

During the eclipse, the moon will appear red, giving it the nickname "blood moon". When this happens, Earth blocks the sunlight that normally reaches the moon.

A "blood moon", meanwhile, gets its name from the reddish hue it turns when the moon passes through the earth's shadow during a lunar eclipse.

South Africa's next total lunar eclipse is early morning of 16 May 2022.

The total eclipse on Friday July 27 will be the longest of the 21st century - from 2001 until 2100 - spanning one hour, 42 minutes and 57 seconds.

The total eclipse will start in Eastern European hubs like Bucharest and Moscow at 10:30 p.m. local time.

It is safe to look at a lunar eclipse without any protective eyewear. "So during totality, those of us on Earth are watching the moon fall in to our shade".

Much like the UK, Australia sits outside the optimal zone but will still catch a glimpse or two of the red moon.

A lunar eclipse usually lasts for a few hours. Although there are three partial solar eclipses this year, none are visible in the U.S.

It is safe to look at the spectacle without any additional protection.

Hundreds of years ago, when people observed the moon during an eclipse, they discovered that the shape of Earth is round. In December 2011, NASA's Lunar Reconnaissance Orbiter gathered data about how quickly the moon's day side (the side that always faces Earth) cools during a lunar eclipse. Scientists use this data to know which areas of the moon are rough with boulders and which are flat.

NASA also studies solar eclipses.
