Blood Moon pictures as early risers see stunning phenomenon

Early risers were able to witness a partial lunar eclipse – or “blood moon” – before dawn on Friday. A “blood moon” is created when the moon moves into Earth’s shadow, gradually darkening before turning red.

In a partial lunar eclipse, the sun, Earth and moon are almost, rather than fully, aligned. This means a dark section appears on the moon. Astronomer Jake Foster, at the Royal Observatory Greenwich, said: “When the Earth comes between the sun and the moon, the only sunlight that can reach the moon must first pass through the Earth’s atmosphere.

“As sunlight enters the atmosphere, different wavelengths (and therefore colours) of light will be scattered and bounced around by differing amounts. Blue light scatters a great deal, which is why our skies are blue.

“Red light is mostly unaffected by the gases of the atmosphere, so it travels all the way through them and out the other side where it can shine on the moon, making it appear red.”

The moon started to turn red at around 5.30am and became most visible just before 6.30am. The last total lunar eclipse was in May 2022 when the moon turned completely red.
