“A little bit of sunlight is refracted by the Earth’s atmosphere and reaches the Moon, bending around the edges of the Earth,” says Walter Freeman, an assistant teaching professor at Syracuse University in New York state.
“This small amount of red light still illuminates the Moon enough for us to see it.”
This kind 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 Earth’s shadow.
The eclipse began at 02:35 GMT on Monday and ended at 07:49 GMT, but the point of greatest eclipse occurred at 05:12 GMT.
The rare celestial event gets the “super” part of its name from the fact that the Moon will be near its closest approach to the Earth – when it will be marginally bigger in the sky than usual.
The “wolf” part comes from the name given to full moons in January – “wolf moons”.
