Christian Rivers and Peter Jackson With a trademark eye for detail, film-maker Peter Jackson has hired an astronomer to ensure the moon’s position in his movie Dambusters is spot-on. A full moon was key to the May 1943 Dambusters raids, in which Allied planes bombed German dams at night. Former Carter Observatory senior astronomer Brian Carter, not related to the founding Carter family, was asked to research the moon’s position over Germany at the time. “Somebody just rang up.

Computer software allows him to find where the moon was at any time, anywhere on the globe. Moon gives light to Jackson film
