On Tuesday, the Moon was bathed in red due to a total lunar eclipse visible from North America to the Pacific but not in Europe.
The totality of the eclipse – when the Moon is completely in Earth’s shadow – lasted between 10:17 and 11:42 GMT.
It was observed in North and Central America, as well as parts of South America, Asia, Australia, and New Zealand.

It was not visible in Europe, which will have to wait until March 14, 2025, for the next total lunar eclipse.
The Moon turns red during a lunar eclipse because the only sunlight reaching the Moon passes through Earth’s atmosphere, according to Nasa on a specially dedicated page on its website.

“During the eclipse, the more dust or clouds in the Earth’s atmosphere, the redder the Moon will appear. It’s as if the Moon is being projected with all of the world’s sunrises and sunsets “Nasa stated.
Why does the Moon appear red during a Total lunar eclipse?
A total lunar eclipse occurs when the Earth passes between the Sun and the Moon, and the Earth’s shadow covers the entire Moon. So, why is the Moon red during it? Surprisingly, this occurs for the same reason that the sky appears blue.
Not all sunlight is blocked during a total lunar eclipse. Some of the light reaches the Moon via the Earth’s atmosphere. However, when light passes through our atmosphere, it scatters in all directions due to a phenomenon known as Rayleigh scattering. Apart from giving our sky its distinctive blue hue, this also means that during a total lunar eclipse, only the redder wavelengths of light pass through our atmosphere and reach the Moon. This is why, during a total eclipse, the Moon appears red.
How to view the lunar eclipse
Although no special equipment is required to observe a lunar eclipse, having binoculars or a telescope can provide a better view of the Moon and its red colour during the eclipse. Furthermore, the best viewing conditions can be found in darker areas away from city lights. The map below shows the locations around the world where different phases of the eclipse will be visible. The coloured contours indicate the edge of the visibility region for each phase.
