The weekly weird
Blood moon and the longest total lunar eclipse of the century
The moon will turn red this month during the longest total lunar eclipse of the 21st century. But don’t worry, it’s not a sign of the apocalypse but a natural wonder caused when Earth passes between the sun and moon.
This year, the eclipse takes place on July 27 and will last one hour and 43 minutes.
The eclipse will be particularly long because the moon will be at one of its furthest points from the Earth, meaning our planet’s shadow is particularly long.
A blood moon is a slightly scarier sounding name for a lunar eclipse. This only occurs when the sun, Earth and moon are aligned when our planet’s satellite passes directly behind the Earth into its umbra (shadow).
Because of this, it gives the moon a reddish-orange colour on the moon, which is why it’s called a blood moon. Whilst astronomers are very excited about the eclipse, doom-mongers fear it heralds the end of the world.
