• Find out what it’s like to live and work in the Earth’s polar extremes at Greenwich from today. The three day ‘Ice World Festival’ centres on the British Antarctic Survey’s vessel, the RRS Sir David Attenborough, which is visiting Greenwich before beginning its first mission to the Antarctic. Visitors will also be able to meet real polar scientists and explorers and see the Boaty McBoatface submersible as well as treasures from the National Maritime Museum’s polar collection including relics from HMS Erebus and Terror and items belonging to Captain Scott and Ernest Shackleton. While the ship can be seen from the dockside, a limited number of tickets are available for walk-up visitors to the festival (advanced booking tickets have sold out). Runs from today until 30th October. Admission is free. For more information, head here.

• More than 200 images – captured by Brazilian photographer Sebastião Salgado over seven years – explore the rich diversity of the Amazon in an exhibition at the Science Museum. Amazônia provides a close-up look at one of the most unique environments on the planet through Salgado’s eyes, including panoramic scenery and the Indigenous peoples of the region (Salgado spent time with 12 different Indigenous groups over his period in the Amazon). Runs until March next year. Admission charge applies. For more, see www.sciencemuseum.org.uk/see-and-do/amazonia.

• Father Christmas with return to The National Gallery for selected dates in November and December. The gallery’s Christmas experience will provide children with the chance to have their photo taken with Santa in his grotto, listen to an elven story in the winter forest set and receive a special token which they can exchange for a gift at the Elven Sorting Office. Meanwhile, Hendrick Avercamp’s painting A Winter Scene with Skaters near a Castle (about 1608–9) will be enlarged and reproduced on a canvas to provide a scenic backdrop for the activities. Admission charge applies. Bookings are now open. For more, head to www.nationalgallery.org.uk/whats-on/meet-father-christmas.
