During this time, people around the world will be able to see a “blood moon”, as the Earth’s satellite turns red. In Portugal, the moon will rise at round 8.45pm tomorrow evening, followed shortly afterwards by the sunset.
The middle of the lunar eclipse will take place at around 9.20pm.
The rare celestial event - said to be the longest in the 21st century - will see the moon will pass through Earth’s darkest shadow and take on a red sheen.
While the eclipse will last 103 minutes, the partial eclipse will be visible for almost four hours.
The rising full moon will also change from shining silver to deep blood-red during the eclipse.
Mars will add to the spectacle shining brightly below the blood moon as it reaches perihelic opposition - where the Red Planet and the sun are on directly opposite sides of Earth.
And those awake after 11pm will be able to catch a glimpse of the International Space Station (ISS), as it moves quickly across the sky from west to east. It will appear like a bright star, before fading from sight a few minutes later.
Unlike a solar eclipse, the lunar event can be viewed without wearing protective eye gear.
The next total lunar eclipse will take place on 19 January, 2019.
