This lunar eclipse will also feature the longest blood moon that the Earth has witnessed in 100 years. Although the lunar eclipse will be visible in all major land areas except North and Central America, the totality will be visible in India, the Middle East, parts of central Asia and eastern and southern Africa. It will not be visible in North America and much of the Pacific Ocean because there it will be morning or afternoon. Spanning for 1 hour 43 minutes, the Blood Moon Lunar Eclipse will see the moon turning to a shade of red.
The next lunar eclipse of such length will happen in 2123.
Not only will you be able to see the blood moon tonight, you may also get a glimpse of the planet Mars, which is at its closest to Earth in 15 years. The lunar eclipse will last for almost two hours, making it the longest to happen in most viewers' lifetime.
During this total eclipse, the Moon - earth's natural satellite - will turn striking shade of red.
"The second cosmic highlight of the night is a total lunar eclipse, known as the Blood Moon, in the early hours of Saturday".
When the moon moved into the conical shadow of the earth, it went from being illuminated by the sun to being dark.
But the eclipse that will stretch from South America to New Zealand on Friday will last nearly four hours, coming in at three hours and 55 minutes.
At 7.13pm South African time, the moon will start moving into the penumbral (partial) shadow of the earth. The moon passed in front of the sun, casting a 70-mile-wide shadow.
The lunar eclipse is beginning to set in across the world right now as the many phases of the Blood Moon begin to materialise. It's the longest full lunar eclipse of the century, so you can be sure that there will be plenty of people with lenses pointed skyward.
People wanting to see the Moon in a spectacular location can take to the Virtual Telescope Project, which will show the Moon from the Roman Forum in Italy.
In less than six months, another total lunar eclipse will take place directly over the Western Hemisphere.
"If Earth partially blocks the sun, and the darkest part of its shadow falls across the moon's surface, it is called a partial eclipse". It happens because, when the sunlight enters Earth's atmosphere which is blocking, the light gets refracted in such a way that the green to violet wavelengths on the visible spectrum scatter more strongly than the red, thus giving the moon a reddish cast.
