Professor Coward is urging Australians across the nation to set their alarms to catch the viewing, or even to continue revelling into the wee hours of the morning.
Mostly a lunar eclipse occurs twice or thrice a year, but today's will be rare due to long duration and visibility across the world. The atmosphere filters out most of the sun's blue light, so the moon looks red.
It will last for 103 minutes, or 1 hour and 43 minutes, making it the longest eclipse of the 21st century. This period of complete lunar eclipse - known as "totality", is the time when the moon appears darkest or reddish in colour.
The eclipse will start at 11:13pm on Friday and end at 5:30am on Saturday in Bangladesh time. But if you happen to be in eastern South America, Europe, Africa, the Middle East, Asia or Australia, you are in luck.
This phenomenon could be explained by the elliptical or oval-shaped orbits that Earth and Mars followed around the Sun.
In addition, the Earth is closer to the Sun during the northern hemisphere summer so its shadow is larger than average, he said. That way you can see the moon move full into the Earth's shadow.
The celestial event, where the moon will line up with the Earth and the sun, will be seen across the United Kingdom and other parts of the Eastern hemisphere.
Before we had explanations before what causes the moon to appear red, ancient cultures often feared the worst.
"The maximum of the eclipse occurs at 21.21 BST, but the upper edge of the Moon won't rise from Belfast until 21:27 BST".
The next lunar eclipse of such length will happen in 2123.
What is Total Lunar Eclipse?
A lunar eclipse or chandra grahan occurs when the Earth while orbiting the Sun comes between the Sun and the Moon, stealing the Moon's shine by blocking the sunlight that is reflected by the natural satellite.
Longest Lunar Eclipse of the Century
'The rim of the earth would be glowing because light is being scattered by the earth's atmosphere'.
Astronomers' telescopes aimed at the blood moon have seen this happening, as well as another mysterious phenomenon - seemingly random spots of heat, often concentrated around craters.
Mr Scagell said: "You may see this very eerie-looking deep-red moon rising".
During the eclipse, the moon will pass through the umbra - the darkest part of the Earth's shadow - and take on a red glow.
The eclipse of the moon will not be visible from North America or most of the Pacific.
"You can't miss Mars right now in the sky right now - it's a bright-red sparkling jewel", said Simon.
The moon travels to a similar position every month, but the tilt of its orbit means it normally passes above or below the Earth's shadow - so most months we have a full moon without an eclipse. It is expected to last for at least two hours.
Where can I watch Chandra Grahan or Lunar Eclipse Online/ Live Stream?
In India, an eclipse or grahan is looked at in awe and wonder.
Unlike a solar eclipse, solar eclipses are safe to view with the naked eye.
No special eye protection is needed as it's a lunar eclipse - just a clear horizon.
