The lunar eclipse that will take place on July 27, is the longest lunar eclipse of the 21st century
There won’t be an eclipse like this for another 100 years!
Weather permitting, there will be a beautiful celestial sight on Friday 27 July, when a total lunar eclipse will be visible from almost all parts of the world.
All you need is a clear view of the night sky. Your eyes are the best instrument to soak up the sight. If you happen to have a pair of binoculars to hand you can use them to range across the craters of the moon but that’s just icing on the cake.
Best of all, you don’t need to wear special filters or protective glasses to view a lunar eclipse. Unlike a total solar eclipse, where it is dangerous to look at the sun, the moon never gets bright enough to cause a danger to your eyes.

Why does the moon turn red?
A total lunar eclipse happens when the sun, Earth and the moon perfectly line up. The most spectacular part about a total lunar eclipse is that when the moon is fully in Earth’s shadow it turns red. This has earned the phenomenon the nickname of blood moon.
The red colour happens because sunlight is deflected through Earth’s atmosphere. The process is called refraction and it bends red light from the sun like a lens into the space behind Earth – and so on to the surface of the eclipsed moon.
The precise colour of the moon depends on the atmospheric conditions in Earth’s atmosphere. The clearer the atmosphere, the brighter and lighter the red colour appears to be.
If Earth had no atmosphere then the totally eclipsed moon would be black.
