A total lunar eclipse brought a “blood moon” over Asia, Europe, and Africa as stargazers marvelled at the sight.
Stargazers enjoyed a “blood moon” during a total lunar eclipse visible across Asia, as well as swaths of Europe and Africa.
When the sun, Earth, and the moon line up, the shadow cast by the planet on its satellite makes it appear an eerie, deep red colour — an effect that has astounded humans for millennia.
People in Asia, including India and China, were best placed to see Sunday’s total eclipse, which was also visible on the eastern edge of Africa as well as in western Australia.
Stargazers in Europe also had a brief chance to see a partial eclipse just as the moon rose during the early evening, but the Americas missed out.
The moon appears red during lunar eclipses because the only sunlight reaching it is “reflected and scattered through the Earth’s atmosphere”, said Ryan Milligan, an astrophysicist at Queen’s University Belfast, Northern Ireland.
Blue wavelengths of light are shorter than red ones, so they are more easily dispersed as they travel through Earth’s atmosphere, he told the AFP news agency.
“That’s what gives the moon its red, bloody colour.”
While special glasses or pinhole projectors are necessary to observe solar eclipses safely, all that is required to view a lunar eclipse is clear weather and a suitable spot.
The last total lunar eclipse was in March this year, while the previous one was in 2022.
