The next time a total lunar eclipse will last this long will be in the year 2123.
Over the night of July 27, and July 28, stargazers will be able to catch a glimpse of the longest lunar eclipse in over a century.
The time that the blood moon is visible depends on what area of the world onlookers are viewing the event from.

The scientific duo supports their theory with the results of recent space missions and analyzes of samples of lunar rocks and soils that show that the Moon is not as dry as scientists long thought.
Total lunar eclipses and total solar eclipses are essentially the reverse of one another.

Fortunately, Indians will be able to watch the total eclipse from start to finish. The moon will take on a red or brown colour during a selenelion because it will be eclipsed by the earth.
To see the lunar eclipse better, you can use telescopes or binoculars.
When the moon rises in the southeast at 8:44 pm the eclipse will have already started, and be in a partial phase.
During the eclipse, the moon will first pass through the Earth's faint shadow known as the penumbra. The best view of it will come after 11.20pm on Friday night.
The moment of greatest eclipse, or maximum eclipse, will occur over the United Kingdom after 9.20pm BST and that will be the moment the moon reaches the dead-centre of the Earth's umbra.More news: Facebook Suffers Huge One-Day Drop in Market Value
