Stargazers have been scanning the skies for sightings of a highly unusual lunar eclipse, which began on Sunday night.
During the spectacle, known as a "super blood wolf moon", the moon appears to glow red while seeming brighter and closer to Earth than normal.
The event was initially visible from North and South America, as well as areas of western Europe. In parts of the UK some clouds obscured the view.
The next total lunar eclipse is expected in two years, on 26 May 2021.
"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."
