Most of the world has a chance to see the moon change colour at the end of the week
A total lunar eclipse will be visible over most of Europe, Asia, Australia and South America on 27 July. Only North America misses the show this time.
During a total lunar eclipse, the moon passes through the Earth’s shadow. Once totally immersed, it turns to a deep red colour. This glorious sight occurs because of the way sunlight bends (refracts) through the Earth’s atmosphere.
