Sky watchers are gearing up for a lunar eclipse, to which some are referring to as a "super wolf of the blood wolf."
During the spectacular event, Earth's natural satellite turns a striking red hue.
The entire eclipse will be visible from North and South America as well as parts of Western Europe (including the UK) and northern Africa.
What is a total lunar eclipse?
This type of eclipse occurs when the Earth passes precisely between the Sun and the Moon.
In this situation, the Sun is behind the Earth and the Moon moves into the shadow of the Earth.
Will the moon appear red?
Yes. Some commentators are referring to the event as a "super wolf's moon of blood." The "super" part comes from the fact that the Moon will be near its closest approach to Earth – when it will be marginally larger in the sky than normal. The "wolf" part comes from the name given to the full moons in January – "wolf moons".
Walter Freeman, an assistant professor of teaching at Syracuse University in New York, said: "A little sunlight is refracted by Earth's atmosphere and reaches the Moon, curving around the edges of the Earth. red light still illuminates the moon long enough for us to see. "
Where and when can I see?
The eclipse starts at 02:35 GMT on Monday and ends at 07:49 GMT, but the period when the entire moon appears in red occurs at 05:12 GMT.
In the United Kingdom, the Moon will be above the horizon during the entire eclipse, although from the southeastern corner of England the Sun has risen when it comes to an end.
This eclipse will also be visible in northwestern France, northwestern Spain, Portugal, a small part of West Africa, almost all of North and South America, the eastern Pacific and the northeastern tip of Russia.
Is it safe to look at?
Although solar eclipses are dangerous to be seen directly, the light from lunar eclipses is much weaker and therefore it is totally safe to see without special equipment.
Why is this significant?
The event is the last chance for sky observers in the UK to see a total lunar eclipse in its entirety until 2029 – weather permitting.

Stages of a total lunar eclipse
Eclipse penumbral begins: This begins when the outer (and lightest) part of the Earth's shadow begins to move on the Moon.
Partial eclipse begins: This stage takes over when the darkest and innermost part of Earth's shadow (umbra) begins to cover the Moon
Total Eclipse begins: Also called wholeness, this occurs when the umbra completely covers the Moon, turning it into a reddish-brown color.
Maximum Eclipse: The midpoint of the totality
Total Eclipse ends: The umbra begins to move away from the face of the Moon after the whole
The partial eclipse ends: The Earth's umbra completely leaves the surface of the Moon
The eclipse of the penumbra ends: The outer part of the shadow (penumbra) completely departs from the Moon
