Dalmatian pelicans on Lake Kerkini in Greece captured over the space of one week (16-21 January 2023) by tour guide photographer Sean Weekly. The Dalmatian pelicans resemble the winged dinosaur pterodactyl as they swoop, splash and feed in the waters of Lake Kerkini in Greece. With wings outstretched, and colourful faces and beaks on display, the birds appear to be in paradise, with the awe-inspiring Kerkini mountains as a mesmerising backdrop.

Some of the best entries so far in the 2016 Insight Astronomy Photographer of the Year competition. There are two weeks left to enter, and the winners will be announced in September. Here: Aurora over Laksvatn Fjord, Laksvatn, Norway. The aurora borealis dances in the skies over the town of Laksvatn, with the Milky Way to the left. The image is a single shot with no compositing, only post-processing to bring out the aurora, and some colour corrections. The photographer Matt Walford said: “I love the way the northern lights look like they are just wistfully dancing over the fjord, framed by the mountains on either side”.

Many deciduous trees have now changed colour as they begin to shed their leaves for Autumn. An extended period of leaf colour change has come about this year due to a warm, dry Spring prompting an early growth spurt and a premature colour change. (Photo by Oli Scarff/Getty Images)
