Lunar Eclipse 2011 December 10 - (PHOTOS) (VIDEO)

Are you ready to see the impossible happen? Tomorrow's lunar eclipse will see the eclipsed moon and the sun visibile in the sky at the same time, during the last total lunar eclipse for 3 years.

The eclipse will be viewable across Asia, Australia and the US and will display an ultra-rare selenellion, an "impossible" occurance according to Fox News.

The selenellion occurs when both the eclipsed moon and the sun are visible in the sky.

During the eclipse the moon will darken and show an unpredictable range of different colours as the Earth blocks the sun's rays. This effect is known as the Rayleigh scattering.

Not only will the moon appear red, it will seem much larger than usual, as it did during June's lunar eclipse.

Best places to see the eclipse include the west coast of the USA, according to Nasa. Residents there will see a total eclipse, as the moon sets and the sun rises, beginning at 3:33 a.m. PST and peaking at 6:30 a.m. PST with a deep red moon.

In the UK, only a partial eclipse will be visible, according to Astronomy. From 3pm tomorrow, the moon will be visible for around an hour, before it disappears.

A graph in the video below shows how visible the eclipse will be across the world.
