The colour change is due to light refraction; blue light waves are blocked from passing through the Earth’s atmosphere.
Red hues do pass through, changing the colour of the Moon to anywhere from copper to deep red.
The term Super Moon comes from the celestial body being at the closest point on its perigee – point of orbit – to the Earth, making it seem larger than usual.
Lastly, Wolf Moon harks back to the Native Americans who gave January’s full Moon this title due to the increase of wolves howling into the night sky throughout January on the run up to their mating season in February.

The eclipse begins on Sunday, January 20 at 9.36pm local time (2.36am Monday, January 21 GMT) with the penumbral eclipse – when the Earth’s outer most shadow begins to touch the Moon.
Then at 10.33pm local time (3.33am Monday GMT) the partial eclipse begins, followed by the maximum eclipse at 12.12am local time (5.12am GMT).
The maximum eclipse will last for 31 minutes, ending at 12.43am local time (5.43am GMT).
For those wishing to watch the eclipse, it is safe to do so without needing eye protection.
A solar eclipse is dangerous to view without specialist equipment due to the impact the Sun’s rays have on the human eye.
However, a total lunar eclipse has no such impact and can be viewed without the danger of damaging eyes.
The best way to see the eclipse is to head away from the light pollution of cities, and into an open space.
This will give a clear view of the night sky and the Moon changing red.
