The shortlisted images in the 2023 Astronomy Photographer of the Year competition have been released by the Royal Observatory Greenwich.
The astrophotography competition, now in its 15th year, is the biggest in the world, and in 2023 received over 4,000 entries from 64 countries around the globe.
This year's shortlisted images include star trails over the First World War trench memorial in Vimy, northern France, the band of our Milky Way galaxy stretching across the sky over an abandoned diamond processing planet in Namibia, and the gas giant Jupiter accompanied by two of its Galilean moons Io and Europa.
Recent aurora activity is also celebrated in a series of images of the Northern Lights, including over the Great Pollet Sea Arch in County Donegal, Ireland.
