The second Blood Moon eclipse of the year will appear on the nightside of Earth tomorrow (Friday, July 27) in the late afternoon to evening hours.
Depending on where you live, you could be treated to the longest total lunar eclipse of the 21st century.
NASA’s Moon experts at the Goddard Space Center estimate the Blood Moon’s totality will last around one hour and 43 minutes.
During this window of totality, refracted sunlight in the Earth’s dusty atmosphere will paint the full Moon a deep red to orange hue.

The eclipse will be predominately visible in the Eastern Hemisphere where the eclipse will run from start to finish.
The eclipse is composed of three distinct phases – the penumbral eclipse, the partial eclipse, and total eclipse.
Countries from Central Asia through to Eastern Africa will see all three phases one after another.
This includes India, Pakistan, Iran, the UAE, Saudi Arabia, Madagascar, South Africa and Egypt.

In the West, the UK, France, Spain, Ghana and Algeria will not see the eclipsed Moon until moonrise.
In the East, the red Moon might not make an appearance until moonset on the morning of Saturday, July 28.
This includes swathes of Southeast Asia, the Pacific and Australia.

Some unlucky nations in South America run the risk of missing the eclipse because the last stages of the Blood Moon will not be visible until the final moments of the eclipse.
Observers in Northern America and Central America are well out of luck because they will still be in the dayside of Earth when the eclipse unfolds.
Moon-gazers in the USA, Canada and Mexico will have to rely instead on lunar eclipse livestreams broadcast on the internet.
