On 11 November 2019, the planet Mercury passed across the face of the Sun from Earth's perspective, in an event known as a Mercury transit.
We received a lot of images of the event from readers who'd manage to take advantage of good conditions and capture the planet's silhouette as it drifted across the solar disc.
Here is a selection of some of our favourites.
