Those gazing up at the skies on Friday, weather permitting, would have seen a penumbral lunar eclipse, which happens when the moon passes through the Earth's shadow.
The phenomenon, which began at 17:00 GMT in the UK and ended at around 21:00, saw the moon move into Earth's penumbra, or outer shadow, causing it to look darker than normal.
Ed Bloomer, an astronomer at the Royal Observatory Greenwich, said people in the UK would be able to see the display "nice and clearly".
